("Apple") makes publicly available and +which contains a notice placed by Apple identifying such program or +work as "Original Code" and stating that it is subject to the terms of +this Apple Public Source License version 2.0 ("License"). As used in +this License: + +1.1 "Applicable Patent Rights" mean: (a) in the case where Apple is +the grantor of rights, (i) claims of patents that are now or hereafter +acquired, owned by or assigned to Apple and (ii) that cover subject +matter contained in the Original Code, but only to the extent +necessary to use, reproduce and/or distribute the Original Code +without infringement; and (b) in the case where You are the grantor of +rights, (i) claims of patents that are now or hereafter acquired, +owned by or assigned to You and (ii) that cover subject matter in Your +Modifications, taken alone or in combination with Original Code. + +1.2 "Contributor" means any person or entity that creates or +contributes to the creation of Modifications. + +1.3 "Covered Code" means the Original Code, Modifications, the +combination of Original Code and any Modifications, and/or any +respective portions thereof. + +1.4 "Externally Deploy" means: (a) to sublicense, distribute or +otherwise make Covered Code available, directly or indirectly, to +anyone other than You; and/or (b) to use Covered Code, alone or as +part of a Larger Work, in any way to provide a service, including but +not limited to delivery of content, through electronic communication +with a client other than You. + +1.5 "Larger Work" means a work which combines Covered Code or portions +thereof with code not governed by the terms of this License. + +1.6 "Modifications" mean any addition to, deletion from, and/or change +to, the substance and/or structure of the Original Code, any previous +Modifications, the combination of Original Code and any previous +Modifications, and/or any respective portions thereof. When code is +released as a series of files, a Modification is: (a) any addition to +or deletion from the contents of a file containing Covered Code; +and/or (b) any new file or other representation of computer program +statements that contains any part of Covered Code. + +1.7 "Original Code" means (a) the Source Code of a program or other +work as originally made available by Apple under this License, +including the Source Code of any updates or upgrades to such programs +or works made available by Apple under this License, and that has been +expressly identified by Apple as such in the header file(s) of such +work; and (b) the object code compiled from such Source Code and +originally made available by Apple under this License. + +1.8 "Source Code" means the human readable form of a program or other +work that is suitable for making modifications to it, including all +modules it contains, plus any associated interface definition files, +scripts used to control compilation and installation of an executable +(object code). + +1.9 "You" or "Your" means an individual or a legal entity exercising +rights under this License. For legal entities, "You" or "Your" +includes any entity which controls, is controlled by, or is under +common control with, You, where "control" means (a) the power, direct +or indirect, to cause the direction or management of such entity, +whether by contract or otherwise, or (b) ownership of fifty percent +(50%) or more of the outstanding shares or beneficial ownership of +such entity. + +2. Permitted Uses; Conditions & Restrictions. Subject to the terms +and conditions of this License, Apple hereby grants You, effective on +the date You accept this License and download the Original Code, a +world-wide, royalty-free, non-exclusive license, to the extent of +Apple's Applicable Patent Rights and copyrights covering the Original +Code, to do the following: + +2.1 Unmodified Code. You may use, reproduce, display, perform, +internally distribute within Your organization, and Externally Deploy +verbatim, unmodified copies of the Original Code, for commercial or +non-commercial purposes, provided that in each instance: + +(a) You must retain and reproduce in all copies of Original Code the +copyright and other proprietary notices and disclaimers of Apple as +they appear in the Original Code, and keep intact all notices in the +Original Code that refer to this License; and + +(b) You must include a copy of this License with every copy of Source +Code of Covered Code and documentation You distribute or Externally +Deploy, and You may not offer or impose any terms on such Source Code +that alter or restrict this License or the recipients' rights +hereunder, except as permitted under Section 6. + +2.2 Modified Code. You may modify Covered Code and use, reproduce, +display, perform, internally distribute within Your organization, and +Externally Deploy Your Modifications and Covered Code, for commercial +or non-commercial purposes, provided that in each instance You also +meet all of these conditions: + +(a) You must satisfy all the conditions of Section 2.1 with respect to +the Source Code of the Covered Code; + +(b) You must duplicate, to the extent it does not already exist, the +notice in Exhibit A in each file of the Source Code of all Your +Modifications, and cause the modified files to carry prominent notices +stating that You changed the files and the date of any change; and + +(c) If You Externally Deploy Your Modifications, You must make +Source Code of all Your Externally Deployed Modifications either +available to those to whom You have Externally Deployed Your +Modifications, or publicly available. Source Code of Your Externally +Deployed Modifications must be released under the terms set forth in +this License, including the license grants set forth in Section 3 +below, for as long as you Externally Deploy the Covered Code or twelve +(12) months from the date of initial External Deployment, whichever is +longer. You should preferably distribute the Source Code of Your +Externally Deployed Modifications electronically (e.g. download from a +web site). + +2.3 Distribution of Executable Versions. In addition, if You +Externally Deploy Covered Code (Original Code and/or Modifications) in +object code, executable form only, You must include a prominent +notice, in the code itself as well as in related documentation, +stating that Source Code of the Covered Code is available under the +terms of this License with information on how and where to obtain such +Source Code. + +2.4 Third Party Rights. You expressly acknowledge and agree that +although Apple and each Contributor grants the licenses to their +respective portions of the Covered Code set forth herein, no +assurances are provided by Apple or any Contributor that the Covered +Code does not infringe the patent or other intellectual property +rights of any other entity. Apple and each Contributor disclaim any +liability to You for claims brought by any other entity based on +infringement of intellectual property rights or otherwise. As a +condition to exercising the rights and licenses granted hereunder, You +hereby assume sole responsibility to secure any other intellectual +property rights needed, if any. For example, if a third party patent +license is required to allow You to distribute the Covered Code, it is +Your responsibility to acquire that license before distributing the +Covered Code. + +3. Your Grants. In consideration of, and as a condition to, the +licenses granted to You under this License, You hereby grant to any +person or entity receiving or distributing Covered Code under this +License a non-exclusive, royalty-free, perpetual, irrevocable license, +under Your Applicable Patent Rights and other intellectual property +rights (other than patent) owned or controlled by You, to use, +reproduce, display, perform, modify, sublicense, distribute and +Externally Deploy Your Modifications of the same scope and extent as +Apple's licenses under Sections 2.1 and 2.2 above. + +4. Larger Works. You may create a Larger Work by combining Covered +Code with other code not governed by the terms of this License and +distribute the Larger Work as a single product. In each such instance, +You must make sure the requirements of this License are fulfilled for +the Covered Code or any portion thereof. + +5. Limitations on Patent License. Except as expressly stated in +Section 2, no other patent rights, express or implied, are granted by +Apple herein. Modifications and/or Larger Works may require additional +patent licenses from Apple which Apple may grant in its sole +discretion. + +6. Additional Terms. You may choose to offer, and to charge a fee for, +warranty, support, indemnity or liability obligations and/or other +rights consistent with the scope of the license granted herein +("Additional Terms") to one or more recipients of Covered Code. +However, You may do so only on Your own behalf and as Your sole +responsibility, and not on behalf of Apple or any Contributor. You +must obtain the recipient's agreement that any such Additional Terms +are offered by You alone, and You hereby agree to indemnify, defend +and hold Apple and every Contributor harmless for any liability +incurred by or claims asserted against Apple or such Contributor by +reason of any such Additional Terms. + +7. Versions of the License. Apple may publish revised and/or new +versions of this License from time to time. Each version will be given +a distinguishing version number. Once Original Code has been published +under a particular version of this License, You may continue to use it +under the terms of that version. You may also choose to use such +Original Code under the terms of any subsequent version of this +License published by Apple. No one other than Apple has the right to +modify the terms applicable to Covered Code created under this +License. + +8. NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in +part pre-release, untested, or not fully tested works. The Covered +Code may contain errors that could cause failures or loss of data, and +may be incomplete or contain inaccuracies. You expressly acknowledge +and agree that use of the Covered Code, or any portion thereof, is at +Your sole and entire risk.

Ownership. Subject to the licenses granted under this License, +each Contributor retains all rights, title and interest in and to any +Modifications made by such Contributor. Apple retains all rights, +title and interest in and to the Original Code and any Modifications +made by or on behalf of Apple ("Apple Modifications"), and such Apple +Modifications will not be automatically subject to this License. Apple +may, at its sole discretion, choose to license such Apple +Modifications under this License, or on different terms from those +contained in this License or may choose not to license them at all. + +12. Termination. + +12.1 Termination. This License and the rights granted hereunder will +terminate: + +(a) automatically without notice from Apple if You fail to comply with +any term(s) of this License and fail to cure such breach within 30 +days of becoming aware of such breach; + +(b) immediately in the event of the circumstances described in Section +13.5(b); or + +(c) automatically without notice from Apple if You, at any time during +the term of this License, commence an action for patent infringement +against Apple; provided that Apple did not first commence +an action for patent infringement against You in that instance. + +12.2 Effect of Termination. Upon termination, You agree to immediately +stop any further use, reproduction, modification, sublicensing and +distribution of the Covered Code. All sublicenses to the Covered Code +which have been properly granted prior to termination shall survive +any termination of this License. Provisions which, by their nature, +should remain in effect beyond the termination of this License shall +survive, including but not limited to Sections 3, 5, 8, 9, 10, 11, +12.2 and 13. No party will be liable to any other for compensation, +indemnity or damages of any sort solely as a result of terminating +this License in accordance with its terms, and termination of this +License will be without prejudice to any other right or remedy of +any party. + +13. Miscellaneous. + +13.1 Government End Users. The Covered Code is a "commercial item" as +defined in FAR 2.101. Government software and technical data rights in +the Covered Code include only those rights customarily provided to the +public as defined in this License. This customary commercial license +in technical data and software is provided in accordance with FAR +12.211 (Technical Data) and 12.212 (Computer Software) and, for +Department of Defense purchases, DFAR 252.227-7015 (Technical Data -- +Commercial Items) and 227.7202-3 (Rights in Commercial Computer +Software or Computer Software Documentation). Accordingly, all U.S. +Government End Users acquire Covered Code with only those rights set +forth herein. + +13.2 Relationship of Parties. This License will not be construed as +creating an agency, partnership, joint venture or any other form of +legal association between or among You, Apple or any Contributor, and +You will not represent to the contrary, whether expressly, by +implication, appearance or otherwise. + +13.3 Independent Development. Nothing in this License will impair +Apple's right to acquire, license, develop, have others develop for +it, market and/or distribute technology or products that perform the +same or similar functions as, or otherwise compete with, +Modifications, Larger Works, technology or products that You may +develop, produce, market or distribute. + +13.4 Waiver; Construction. Failure by Apple or any Contributor to +enforce any provision of this License will not be deemed a waiver of +future enforcement of that or any other provision. Any law or +regulation which provides that the language of a contract shall be +construed against the drafter will not apply to this License. + +13.5 Severability. (a) If for any reason a court of competent +jurisdiction finds any provision of this License, or portion thereof, +to be unenforceable, that provision of the License will be enforced to +the maximum extent permissible so as to effect the economic benefits +and intent of the parties, and the remainder of this License will +continue in full force and effect. (b) Notwithstanding the foregoing, +if applicable law prohibits or restricts You from fully and/or +specifically complying with Sections 2 and/or 3 or prevents the +enforceability of either of those Sections, this License will +immediately terminate and You must immediately discontinue any use of +the Covered Code and destroy all copies of it that are in your +possession or control. + +13.6 Dispute Resolution. Any litigation or other dispute resolution +between You and Apple relating to this License shall take place in the +Northern District of California, and You and Apple hereby consent to +the personal jurisdiction of, and venue in, the state and federal +courts within that District with respect to this License. The +application of the United Nations Convention on Contracts for the +International Sale of Goods is expressly excluded. + +13.7 Entire Agreement; Governing Law. This License constitutes the +entire agreement between the parties with respect to the subject +matter hereof. This License shall be governed by the laws of the +United States and the State of California, except that body of +California law concerning conflicts of law. + +Where You are located in the province of Quebec, Canada, the following +clause applies: The parties hereby confirm that they have requested +that this License and all related documents be drafted in English. Les +parties ont exige que le present contrat et tous les documents +connexes soient rediges en anglais. + +EXHIBIT A. + +"Portions Copyright (c) 1999-2003 Apple Computer, Inc.

A process may specify a +.Em handler +to which a signal is delivered, or specify that a signal is to be +.Em blocked +or +.Em ignored . +A process may also specify that a default action is to be taken +by the system when a signal occurs. +Normally, signal handlers execute on the current stack +of the process. This may be changed, on a per-handler basis, +so that signals are taken on a special +.Em "signal stack" . +.Pp +All signals have the same +.Em priority . +Signal routines execute with the signal that caused their +invocation +.Em blocked , +but other signals may yet occur. +A global +.Em "signal mask" +defines the set of signals currently blocked from delivery +to a process. The signal mask for a process is initialized +from that of its parent (normally 0). It +may be changed with a +.Xr sigblock 2 +or +.Xr sigsetmask 2 +call, or when a signal is delivered to the process. +.Pp +When a signal +condition arises for a process, the signal is added to a set of +signals pending for the process. If the signal is not currently +.Em blocked +by the process then it is delivered to the process. When a signal +is delivered, the current state of the process is saved, +a new signal mask is calculated (as described below), +and the signal handler is invoked. The call to the handler +is arranged so that if the signal handling routine returns +normally the process will resume execution in the context +from before the signal's delivery. +If the process wishes to resume in a different context, then it +must arrange to restore the previous context itself. +.Pp +When a signal is delivered to a process a new signal mask is +installed for the duration of the process' signal handler +(or until a +.Xr sigblock 2 +or +.Xr sigsetmask 2 +call is made). +This mask is formed by taking the current signal mask, +adding the signal to be delivered, and +.Em or Ns 'ing +in the signal mask associated with the handler to be invoked. +.Pp +.Fn Sigvec +assigns a handler for a specific signal. If +.Fa vec +is non-zero, it +specifies a handler routine and mask +to be used when delivering the specified signal. +Further, if the +.Dv SV_ONSTACK +bit is set in +.Fa sv_flags , +the system will deliver the signal to the process on a +.Em "signal stack" , +specified with +.Xr sigaltstack 2 . +If +.Fa ovec +is non-zero, the previous handling information for the signal +is returned to the user. +.Pp +The following is a list of all signals +with names as in the include file +.Aq Pa signal.h : +.Bl -column SIGVTALARMXX "create core imagexxx" +.It Sy "NAME Default Action Description" +.It Dv SIGHUP No " terminate process" " terminal line hangup" +.It Dv SIGINT No " terminate process" " interrupt program" +.It Dv SIGQUIT No " create core image" " quit program" +.It Dv SIGILL No " create core image" " illegal instruction" +.It Dv SIGTRAP No " create core image" " trace trap" +.It Dv SIGABRT No " create core image" Ta Xr abort 3 +call (formerly +.Dv SIGIOT ) +.It Dv SIGEMT No " create core image" " emulate instruction executed" +.It Dv SIGFPE No " create core image" " floating-point exception" +.It Dv SIGKILL No " terminate process" " kill program" +.It Dv SIGBUS No " create core image" " bus error" +.It Dv SIGSEGV No " create core image" " segmentation violation" +.It Dv SIGSYS No " create core image" " non-existent system call invoked" +.It Dv SIGPIPE No " terminate process" " write on a pipe with no reader" +.It Dv SIGALRM No " terminate process" " real-time timer expired" +.It Dv SIGTERM No " terminate process" " software termination signal" +.It Dv SIGURG No " discard signal" " urgent condition present on socket" +.It Dv SIGSTOP No " stop process" " stop (cannot be caught or ignored)" +.It Dv SIGTSTP No " stop process" " stop signal generated from keyboard" +.It Dv SIGCONT No " discard signal" " continue after stop" +.It Dv SIGCHLD No " discard signal" " child status has changed" +.It Dv SIGTTIN No " stop process" " background read attempted from control terminal" +.It Dv SIGTTOU No " stop process" " background write attempted to control terminal" +.It Dv SIGIO No " discard signal" Tn " I/O" +is possible on a descriptor (see +.Xr fcntl 2 ) +.It Dv SIGXCPU No " terminate process" " cpu time limit exceeded (see" +.Xr setrlimit 2 ) +.It Dv SIGXFSZ No " terminate process" " file size limit exceeded (see" +.Xr setrlimit 2 ) +.It Dv SIGVTALRM No " terminate process" " virtual time alarm (see" +.Xr setitimer 2 ) +.It Dv SIGPROF No " terminate process" " profiling timer alarm (see" +.Xr setitimer 2 ) +.It Dv SIGWINCH No " discard signal" " Window size change" +.It Dv SIGINFO No " discard signal" " status request from keyboard" +.It Dv SIGUSR1 No " terminate process" " User defined signal 1" +.It Dv SIGUSR2 No " terminate process" " User defined signal 2" +.El +.Pp +Once a signal handler is installed, it remains installed +until another +.Fn sigvec +call is made, or an +.Xr execve 2 +is performed. +A signal-specific default action may be reset by +setting +.Fa sv_handler +to +.Dv SIG_DFL . +The defaults are process termination, possibly with core dump; +no action; stopping the process; or continuing the process. +See the above signal list for each signal's default action. +If +.Fa sv_handler +is +.Dv SIG_IGN +current and pending instances +of the signal are ignored and discarded. +.Pp +If a signal is caught during the system calls listed below, +the call is normally restarted. +The call can be forced to terminate prematurely with an +.Er EINTR +error return by setting the +.Dv SV_INTERRUPT +bit in +.Fa sv_flags . +The affected system calls include +.Xr read 2 , +.Xr write 2 , +.Xr sendto 2 , +.Xr recvfrom 2 , +.Xr sendmsg 2 +and +.Xr recvmsg 2 +on a communications channel or a slow device (such as a terminal, +but not a regular file) +and during a +.Xr wait 2 +or +.Xr ioctl 2 . +However, calls that have already committed are not restarted, +but instead return a partial success (for example, a short read count). +.Pp +After a +.Xr fork 2 +or +.Xr vfork 2 +all signals, the signal mask, the signal stack, +and the restart/interrupt flags are inherited by the child. +.Pp +.Xr Execve 2 +reinstates the default +action for all signals which were caught and +resets all signals to be caught on the user stack. +Ignored signals remain ignored;

for example, +big endian order would be the number 4,321. +If +.Va lorder +is 0 (no order is specified) the current host order is used. +.El +.Pp +If the file already exists (and the +.Dv O_TRUNC +flag is not specified), the +values specified for the +.Va flags , lorder +and +.Va psize +arguments +are ignored +in favor of the values used when the tree was created. +.Pp +Forward sequential scans of a tree are from the least key to the greatest. +.Pp +Space freed up by deleting key/data pairs from the tree is never reclaimed, +although it is normally made available for reuse. +This means that the +.Nm +storage structure is grow-only. +The only solutions are to avoid excessive deletions, or to create a fresh +tree periodically from a scan of an existing one. +.Pp +Searches, insertions, and deletions in a +.Nm +will all complete in +O lg base N where base is the average fill factor. +Often, inserting ordered data into +.Nm Ns s +results in a low fill factor. +This implementation has been modified to make ordered insertion the best +case, resulting in a much better than normal page fill factor. +.Sh ERRORS +The +.Nm +access method routines may fail and set +.Va errno +for any of the errors specified for the library routine +.Xr dbopen 3 . +.Sh SEE ALSO +.Xr dbopen 3 , +.Xr hash 3 , +.Xr mpool 3 , +.Xr recno 3 +.Rs +.%T "The Ubiquitous B-tree" +.%A Douglas Comer +.%J "ACM Comput.

The thread safe mechanism should be lightweight so the library can + * be used by non-threaded applications without unreasonable overhead. + * + * 2.

The library should be able to be compiled without support for thread + * safety. + * + * + * Rationale: + * + * One approach for thread safety is to provide discrete versions of the + * library: one thread safe, the other not. The disadvantage of this is + * that libc is rather large, and two copies of a library which are 99%+ + * identical is not an efficent use of resources. + * + * Another approach is to provide a single thread safe library. However, + * it should not add significant run time or code size overhead to non- + * threaded applications. + * + * Since the NetBSD C library is used in other projects, it should be + * easy to replace the mutual exclusion primitives with ones provided by + * another system. Similarly, it should also be easy to remove all + * support for thread safety completely if the target environment does + * not support threads. + * + * + * Implementation Details: + * + * The mutex primitives used by the library (mutex_t, mutex_lock, etc.) + * are macros which expand to the cooresponding primitives provided by + * the thread engine or to nothing. The latter is used so that code is + * not unreasonably cluttered with #ifdefs when all thread safe support + * is removed. + * + * The mutex macros can be directly mapped to the mutex primitives from + * pthreads, however it should be reasonably easy to wrap another mutex + * implementation so it presents a similar interface. + * + * Stub implementations of the mutex functions are provided with *weak* + * linkage. These functions simply return success. When linked with a + * thread library (i.e. -lpthread), the functions will override the + * stubs. + */ + +#include +#include "libc_private.h" + +#define mutex_t pthread_mutex_t +#define cond_t pthread_cond_t +#define rwlock_t pthread_rwlock_t +#define once_t pthread_once_t + +#define thread_key_t pthread_key_t +#define MUTEX_INITIALIZER PTHREAD_MUTEX_INITIALIZER +#define RWLOCK_INITIALIZER PTHREAD_RWLOCK_INITIALIZER +#define ONCE_INITIALIZER PTHREAD_ONCE_INIT + +#define mutex_init(m, a) _pthread_mutex_init(m, a) +#define mutex_lock(m) if (__isthreaded) \ + _pthread_mutex_lock(m) +#define mutex_unlock(m) if (__isthreaded) \ + _pthread_mutex_unlock(m) +#define mutex_trylock(m) (__isthreaded ? 0 : _pthread_mutex_trylock(m)) + +#define cond_init(c, a, p) _pthread_cond_init(c, a) +#define cond_signal(m) if (__isthreaded) \ + _pthread_cond_signal(m) +#define cond_broadcast(m) if (__isthreaded) \ + _pthread_cond_broadcast(m) +#define cond_wait(c, m) if (__isthreaded) \ + _pthread_cond_wait(c, m) + +#define rwlock_init(l, a) _pthread_rwlock_init(l, a) +#define rwlock_rdlock(l) if (__isthreaded) \ + _pthread_rwlock_rdlock(l) +#define rwlock_wrlock(l) if (__isthreaded) \ + _pthread_rwlock_wrlock(l) +#define rwlock_unlock(l) if (__isthreaded) \ + _pthread_rwlock_unlock(l) + +#define thr_keycreate(k, d) _pthread_key_create(k, d) +#define thr_setspecific(k, p) _pthread_setspecific(k, p) +#define thr_getspecific(k) _pthread_getspecific(k) +#define thr_sigsetmask(f, n, o) _pthread_sigmask(f, n, o) + +#define thr_once(o, i) _pthread_once(o, i) +#define thr_self() _pthread_self() +#define thr_exit(x) _pthread_exit(x) +#define thr_main() _pthread_main_np() diff --git a/fbsdcompat/spinlock.h b/fbsdcompat/spinlock.h new file mode 100644 index 0000000..b3417ce --- /dev/null +++ b/fbsdcompat/spinlock.h @@ -0,0 +1,113 @@ +/* + * Copyright (c) 2003 Apple Computer, Inc.

We scale relevant + * quantities using O(log2(k)) rather than O(k) multiplications. + * 2. For some modes > 2 (corresponding to ecvt and fcvt), we don't + * try to generate digits strictly left to right. Instead, we + * compute with fewer bits and propagate the carry if necessary + * when rounding the final digit up. This is often faster. + * 3. Under the assumption that input will be rounded nearest, + * mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22. + * That is, we allow equality in stopping tests when the + * round-nearest rule will give the same floating-point value + * as would satisfaction of the stopping test with strict + * inequality. + * 4. We remove common factors of powers of 2 from relevant + * quantities. + * 5. When converting floating-point integers less than 1e16, + * we use floating-point arithmetic rather than resorting + * to multiple-precision integers. + * 6. When asked to produce fewer than 15 digits, we first try + * to get by with floating-point arithmetic; we resort to + * multiple-precision integer arithmetic only if we cannot + * guarantee that the floating-point calculation has given + * the correctly rounded result. For k requested digits and + * "uniformly" distributed input, the probability is + * something like 10^(k-15) that we must resort to the Long + * calculation. + */ + + char * +gdtoa +#ifdef KR_headers + (fpi, be, bits, kindp, mode, ndigits, decpt, rve) + FPI *fpi; int be; ULong *bits; + int *kindp, mode, ndigits, *decpt; char **rve; +#else + (FPI *fpi, int be, ULong *bits, int *kindp, int mode, int ndigits, int *decpt, char **rve) +#endif +{ + /* Arguments ndigits and decpt are similar to the second and third + arguments of ecvt and fcvt; trailing zeros are suppressed from + the returned string.

On such machines, you can + * #define Just_16 to store 16 bits per 32-bit Long when doing + * high-precision integer arithmetic. Whether this speeds things + * up or slows things down depends on the machine and the number + * being converted.

The subsystem is re-seeded from the kernel random number +subsystem on a regular basis, and also upon +.Xr fork 2 . +.Pp +This family of functions provides higher quality random data than those +described in +.Xr rand 3 , +.Xr random 3 , +and +.Xr rand48 3 . +They can be called in almost all environments, including +.Xr chroot 2 , +and their use is encouraged over all other standard library functions for +random numbers. +.Pp +.Fn arc4random +returns a single 32-bit value. +.Pp +.Fn arc4random_buf +fills the region +.Fa buf +of length +.Fa nbytes +with random data. +.Pp +.Fn arc4random_uniform +will return a single 32-bit value, uniformly distributed but less than +.Fa upper_bound . +This is recommended over constructions like +.Dq Li arc4random() % upper_bound +as it avoids "modulo bias" when the upper bound is not a power of two. +In the worst case, this function may require multiple iterations +to ensure uniformity. +.Sh RETURN VALUES +These functions are always successful, and no return value is +reserved to indicate an error. +.Sh SEE ALSO +.Xr rand 3 , +.Xr rand48 3 , +.Xr random 3 , +.Xr random 4 +.Sh HISTORY +The original version of this random number generator used the RC4 (also known +as ARC4) algorithm.

process image with a +new process image. +The functions described in this manual page are front-ends for the function +.Xr execve 2 . +(See the manual page for +.Xr execve 2 +for detailed information about the replacement of the current process.) +.Pp +The initial argument for these functions is the pathname of a file which +is to be executed. +.Pp +The +.Fa "const char *arg0" +and subsequent ellipses in the +.Fn execl , +.Fn execlp , +and +.Fn execle +functions can be thought of as +.Em arg0 , +.Em arg1 , +\&..., +.Em argn . +Together they describe a list of one or more pointers to null-terminated +strings that represent the argument list available to the executed program. +The first argument, by convention, should point to the file name associated +with the file being executed. +The list of arguments +.Em must +be terminated by a +.Dv NULL +pointer. +.Pp +The +.Fn execv , +.Fn execvp , +and +.Fn execvP +functions provide an array of pointers to null-terminated strings that +represent the argument list available to the new program. +The first argument, by convention, should point to the file name associated +with the file being executed. +The array of pointers +.Sy must +be terminated by a +.Dv NULL +pointer. +.Pp +The +.Fn execle +function also specifies the environment of the executed process +by following the +.Dv NULL +pointer that terminates the list of arguments in the argument list +or the pointer to the argv array with an additional argument. +This additional argument is an array of pointers to null-terminated strings +and +.Em must +be terminated by a +.Dv NULL +pointer. +The other functions take the environment for the new process image from the +external variable +.Va environ +in the current process. +.Pp +Some of these functions have special semantics. +.Pp +The functions +.Fn execlp , +.Fn execvp , +and +.Fn execvP +will duplicate the actions of the shell in searching for an executable file +if the specified file name does not contain a slash +.Dq Li / +character. +For +.Fn execlp +and +.Fn execvp , +search path is the path specified in the environment by +.Dq Ev PATH +variable. +If this variable is not specified, +the default path is set according to the +.Dv _PATH_DEFPATH +definition in +.In paths.h , +which is set to +.Dq Ev /usr/bin:/bin . +For +.Fn execvP , +the search path is specified as an argument to the function. +In addition, certain errors are treated specially. +.Pp +If an error is ambiguous (for simplicity, we shall consider all +errors except +.Er ENOEXEC +as being ambiguous here, although only the critical error +.Er EACCES +is really ambiguous), +then these functions will act as if they stat the file to determine +whether the file exists and has suitable execute permissions. +If it does, they will return immediately with the global variable +.Va errno +restored to the value set by +.Fn execve . +Otherwise, the search will be continued. +If the search completes without performing a successful +.Fn execve +or terminating due to an error, +these functions will return with the global variable +.Va errno +set to +.Er EACCES +or +.Er ENOENT +according to whether at least one file with suitable execute permissions +was found. +.Pp +If the header of a file is not recognized (the attempted +.Fn execve +returned +.Er ENOEXEC ) , +these functions will execute the shell with the path of +the file as its first argument. +(If this attempt fails, no further searching is done.) +.Sh RETURN VALUES +If any of the +.Fn exec +functions returns, an error will have occurred. +The return value is \-1, and the global variable +.Va errno +will be set to indicate the error. +.Sh FILES +.Bl -tag -width /bin/sh -compact +.It Pa /bin/sh +The shell. +.El +.Sh COMPATIBILITY +Historically, the default path for the +.Fn execlp +and +.Fn execvp +functions was +.Dq Pa :/bin:/usr/bin . +This was changed to place the current directory last to enhance system +security. +.Pp +The behavior of +.Fn execlp +and +.Fn execvp +when errors occur while attempting to execute the file is not quite historic +practice, and has not traditionally been documented and is not specified +by the +.Tn POSIX +standard. +.Pp +Traditionally, the functions +.Fn execlp +and +.Fn execvp +ignored all errors except for the ones described above and +.Er ETXTBSY , +upon which they retried after sleeping for several seconds, and +.Er ENOMEM +and +.Er E2BIG , +upon which they returned. +They now return for +.Er ETXTBSY , +and determine existence and executability more carefully. +In particular, +.Er EACCES +for inaccessible directories in the path prefix is no longer +confused with +.Er EACCES +for files with unsuitable execute permissions. +In +.Bx 4.4 , +they returned upon all errors except +.Er EACCES , +.Er ENOENT , +.Er ENOEXEC +and +.Er ETXTBSY . +This was inferior to the traditional error handling, +since it breaks the ignoring of errors for path prefixes +and only improves the handling of the unusual ambiguous error +.Er EFAULT +and the unusual error +.Er EIO . +The behaviour was changed to match the behaviour of +.Xr sh 1 . +.Sh ERRORS +The +.Fn execl , +.Fn execle , +.Fn execlp , +.Fn execvp , +and +.Fn execvP +functions +may fail and set +.Va errno +for any of the errors specified for the library functions +.Xr execve 2 +and +.Xr malloc 3 . +.Pp +The

0 is returned and \-1 on failure. +.Pp +The +.Fn cgetmatch +function will return 0 if +.Fa name +is one of the names of the capability record +.Fa buf , +\-1 if +not. +.Pp +The +.Fn cgetcap +function searches the capability record +.Fa buf +for the capability +.Fa cap +with type +.Fa type . +A +.Fa type +is specified using any single character. +If a colon (`:') is used, an +untyped capability will be searched for (see below for explanation of +types). +A pointer to the value of +.Fa cap +in +.Fa buf +is returned on success, +.Dv NULL +if the requested capability could not be +found. +The end of the capability value is signaled by a `:' or +.Tn ASCII +.Dv NUL +(see below for capability database syntax). +.Pp +The +.Fn cgetnum +function retrieves the value of the numeric capability +.Fa cap +from the capability record pointed to by +.Fa buf . +The numeric value is returned in the +.Ft long +pointed to by +.Fa num . +0 is returned on success, \-1 if the requested numeric capability could not +be found. +.Pp +The +.Fn cgetstr +function retrieves the value of the string capability +.Fa cap +from the capability record pointed to by +.Fa buf . +A pointer to a decoded, +.Dv NUL +terminated, +.Xr malloc 3 Ns \&'d +copy of the string is returned in the +.Ft char * +pointed to by +.Fa str . +The number of characters in the decoded string not including the trailing +.Dv NUL +is returned on success, \-1 if the requested string capability could not +be found, \-2 if a system error was encountered (storage allocation +failure). +.Pp +The +.Fn cgetustr +function is identical to +.Fn cgetstr +except that it does not expand special characters, but rather returns each +character of the capability string literally. +.Pp +The +.Fn cgetfirst +and +.Fn cgetnext +functions comprise a function group that provides for sequential +access of the +.Dv NULL +pointer terminated array of file names, +.Fa db_array . +The +.Fn cgetfirst +function returns the first record in the database and resets the access +to the first record. +The +.Fn cgetnext +function returns the next record in the database with respect to the +record returned by the previous +.Fn cgetfirst +or +.Fn cgetnext +call. +If there is no such previous call, the first record in the database is +returned. +Each record is returned in a +.Xr malloc 3 Ns \&'d +copy pointed to by +.Fa buf . +.Ic Tc +expansion is done (see +.Ic tc= +comments below). +Upon completion of the database 0 is returned, 1 is returned upon successful +return of record with possibly more remaining (we have not reached the end of +the database yet), 2 is returned if the record contains an unresolved +.Ic tc +expansion, \-1 is returned if a system error occurred, and \-2 +is returned if a potential reference loop is detected (see +.Ic tc= +comments below). +Upon completion of database (0 return) the database is closed. +.Pp +The +.Fn cgetclose +function closes the sequential access and frees any memory and file descriptors +being used. +Note that it does not erase the buffer pushed by a call to +.Fn cgetset . +.Sh CAPABILITY DATABASE SYNTAX +Capability databases are normally +.Tn ASCII +and may be edited with standard +text editors. +Blank lines and lines beginning with a `#' are comments +and are ignored. +Lines ending with a `\|\e' indicate that the next line +is a continuation of the current line; the `\|\e' and following newline +are ignored. +Long lines are usually continued onto several physical +lines by ending each line except the last with a `\|\e'. +.Pp +Capability databases consist of a series of records, one per logical +line. +Each record contains a variable number of `:'-separated fields +(capabilities). +Empty fields consisting entirely of white space +characters (spaces and tabs) are ignored. +.Pp +The first capability of each record specifies its names, separated by `|' +characters. +These names are used to reference records in the database. +By convention, the last name is usually a comment and is not intended as +a lookup tag. +For example, the +.Em vt100 +record from the +.Xr termcap 5 +database begins: +.Pp +.Dl "d0\||\|vt100\||\|vt100-am\||\|vt100am\||\|dec vt100:" +.Pp +giving four names that can be used to access the record. +.Pp +The remaining non-empty capabilities describe a set of (name, value) +bindings, consisting of a names optionally followed by a typed value: +.Bl -column "nameTvalue" +.It name Ta "typeless [boolean] capability" +.Em name No "is present [true]" +.It name Ns Em \&T Ns value Ta capability +.Pq Em name , \&T +has value +.Em value +.It name@ Ta "no capability" Em name No exists +.It name Ns Em T Ns \&@ Ta capability +.Pq Em name , T +does not exist +.El +.Pp +Names consist of one or more characters. +Names may contain any character +except `:', but it is usually best to restrict them to the printable +characters and avoid use of graphics like `#', `=', `%', `@', etc. +Types +are single characters used to separate capability names from their +associated typed values. +Types may be any character except a `:'. +Typically, graphics like `#', `=', `%', etc.\& are used. +Values may be any +number of characters and may contain any character except `:'. +.Sh CAPABILITY DATABASE SEMANTICS +Capability records describe a set of (name, value) bindings. +Names may +have multiple values bound to them. +Different values for a name are +distinguished by their +.Fa types . +The +.Fn cgetcap +function will return a pointer to a value of a name given the capability +name and the type of the value. +.Pp +The types `#' and `=' are conventionally used to denote numeric and +string typed values, but no restriction on those types is enforced. +The +functions +.Fn cgetnum +and +.Fn cgetstr +can be used to implement the traditional syntax and semantics of `#' +and `='. +Typeless capabilities are typically used to denote boolean objects with +presence or absence indicating truth and false values respectively. +This interpretation is conveniently represented by: +.Pp +.Dl "(getcap(buf, name, ':') != NULL)" +.Pp +A special capability, +.Ic tc= name , +is used to indicate that the record specified by +.Fa name +should be substituted for the +.Ic tc +capability. +.Ic Tc +capabilities may interpolate records which also contain +.Ic tc +capabilities and more than one +.Ic tc +capability may be used in a record. +A +.Ic tc +expansion scope (i.e., where the argument is searched for) contains the +file in which the +.Ic tc +is declared and all subsequent files in the file array. +.Pp +When a database is searched for a capability record, the first matching +record in the search is returned. +When a record is scanned for a +capability, the first matching capability is returned; the capability +.Ic :nameT@: +will hide any following definition of a value of type +.Em T +for +.Fa name ; +and the capability +.Ic :name@: +will prevent any following values of +.Fa name +from being seen. +.Pp +These features combined with +.Ic tc +capabilities can be used to generate variations of other databases and +records by either adding new capabilities, overriding definitions with new +definitions, or hiding following definitions via `@' capabilities. +.Sh EXAMPLES +.Bd -unfilled -offset indent +example\||\|an example of binding multiple values to names:\e + :foo%bar:foo^blah:foo@:\e + :abc%xyz:abc^frap:abc$@:\e + :tc=more: +.Ed +.Pp +The capability foo has two values bound to it (bar of type `%' and blah of +type `^') and any other value bindings are hidden. +The capability abc +also has two values bound but only a value of type `$' is prevented from +being defined in the capability record more. +.Pp +.Bd -unfilled -offset indent +file1: + new\||\|new_record\||\|a modification of "old":\e + :fript=bar:who-cares@:tc=old:blah:tc=extensions: +file2: + old\||\|old_record\||\|an old database record:\e + :fript=foo:who-cares:glork#200: +.Ed +.Pp +The records are extracted by calling +.Fn cgetent +with file1 preceding file2. +In the capability record new in file1, fript=bar overrides the definition +of fript=foo interpolated from the capability record old in file2, +who-cares@ prevents the definition of any who-cares definitions in old +from being seen, glork#200 is inherited from old, and blah and anything +defined by the record extensions is added to those definitions in old. +Note that the position of the fript=bar and who-cares@ definitions before +tc=old is important here. +If they were after, the definitions in old +would take precedence. +.Sh CGETNUM AND CGETSTR SYNTAX AND SEMANTICS +Two types are predefined by +.Fn cgetnum +and +.Fn cgetstr : +.Bl -column "nameXnumber" +.Sm off +.It Em name No \&# Em number Ta numeric +.Sm on +capability +.Em name +has value +.Em number +.Sm off +.It Em name No = Em string Ta "string capability" +.Sm on +.Em name +has value +.Em string +.Sm off +.It Em name No \&#@ Ta "the numeric capability" +.Sm on +.Em name +does not exist +.Sm off +.It Em name No \&=@ Ta "the string capability" +.Sm on +.Em name +does not exist +.El +.Pp +Numeric capability values may be given in one of three numeric bases. +If the number starts with either +.Ql 0x +or +.Ql 0X +it is interpreted as a hexadecimal number (both upper and lower case a-f +may be used to denote the extended hexadecimal digits). +Otherwise, if the number starts with a +.Ql 0 +it is interpreted as an octal number. +Otherwise the number is interpreted as a decimal number. +.Pp +String capability values may contain any character. +Non-printable +.Dv ASCII +codes, new lines, and colons may be conveniently represented by the use +of escape sequences: +.Bl -column "\e\|X,X\e\|X" "(ASCII octal nnn)" +^X ('X' & 037) control-X +\e\|b, \e\|B (ASCII 010) backspace +\e\|t, \e\|T (ASCII 011) tab +\e\|n, \e\|N (ASCII 012) line feed (newline) +\e\|f, \e\|F (ASCII 014) form feed +\e\|r, \e\|R (ASCII 015) carriage return +\e\|e, \e\|E (ASCII 027) escape +\e\|c, \e\|C (:) colon +\e\|\e (\e\|) back slash +\e\|^ (^) caret +\e\|nnn (ASCII octal nnn) +.El +.Pp +A `\|\e' may be followed by up to three octal digits directly specifies +the numeric code for a character. +The use of +.Tn ASCII +.Dv NUL Ns s , +while easily +encoded, causes all sorts of problems and must be used with care since +.Dv NUL Ns s +are typically used to denote the end of strings; many applications +use `\e\|200' to represent a +.Dv NUL . +.Sh DIAGNOSTICS +The +.Fn cgetent , +.Fn cgetset , +.Fn cgetmatch , +.Fn cgetnum , +.Fn cgetstr , +.Fn cgetustr , +.Fn cgetfirst , +and +.Fn cgetnext +functions +return a value greater than or equal to 0 on success and a value less +than 0 on failure. +The +.Fn cgetcap +function returns a character pointer on success and a +.Dv NULL +on failure. +.Pp +The +.Fn cgetent , +and +.Fn cgetset +functions may fail and set +.Va errno +for any of the errors specified for the library functions: +.Xr fopen 3 , +.Xr fclose 3 , +.Xr open 2 , +and +.Xr close 2 . +.Pp +The +.Fn cgetent , +.Fn cgetset , +.Fn cgetstr , +and +.Fn cgetustr +functions +may fail and set +.Va errno +as follows: +.Bl -tag -width Er +.It Bq Er ENOMEM +No memory to allocate. +.El +.Sh SEE ALSO +.Xr cap_mkdb 1 , +.Xr malloc 3 +.Sh BUGS +Colons (`:') cannot be used in names, types, or values. +.Pp +There are no checks for +.Ic tc Ns

thus, its contents are lost after +each new call to +.Fn seed48 . +.Pp +Finally, +.Fn lcong48 +allows full control over the multiplicand and addend used in +.Fn drand48 , +.Fn erand48 , +.Fn lrand48 , +.Fn nrand48 , +.Fn mrand48 , +and +.Fn jrand48 , +and the seed used in +.Fn drand48 , +.Fn lrand48 , +and +.Fn mrand48 . +An array of 7 shorts is passed as argument; the first three shorts are +used to initialize the seed; the second three are used to initialize the +multiplicand; and the last short is used to initialize the addend. +It is thus not possible to use values greater than 0xffff as the addend. +.Pp +Note that all three methods of seeding the random number generator +always also set the multiplicand and addend for any of the six +generator calls. +.Pp +For a more powerful random number generator, see +.Xr random 3 . +.Sh SEE ALSO +.Xr rand 3 , +.Xr random 3 +.Sh AUTHORS +.An Martin Birgmeier diff --git a/gen/FreeBSD/rand48.h b/gen/FreeBSD/rand48.h new file mode 100644 index 0000000..e799eba --- /dev/null +++ b/gen/FreeBSD/rand48.h @@ -0,0 +1,81 @@ +/* + * Copyright (c) 1993 Martin Birgmeier + * All rights reserved. + * + * You may redistribute unmodified or modified versions of this source + * code provided that the above copyright notice and this and the + * following conditions are retained. + * + * This software is provided ``as is'', and comes with no warranties + * of any kind.

+some signals instead cause the process receiving them to be stopped, +or are simply discarded if the process has not requested otherwise. +Except for the +.Dv SIGKILL +and +.Dv SIGSTOP +signals, the +.Fn signal +function allows for a signal to be caught, to be ignored, or to generate +an interrupt. +These signals are defined in the file +.In signal.h : +.Bl -column No ".Dv SIGVTALRM" "create core image" +.It Sy "No Name Default Action Description" +.It 1 Ta Dv SIGHUP Ta "terminate process" Ta "terminal line hangup" +.It 2 Ta Dv SIGINT Ta "terminate process" Ta "interrupt program" +.It 3 Ta Dv SIGQUIT Ta "create core image" Ta "quit program" +.It 4 Ta Dv SIGILL Ta "create core image" Ta "illegal instruction" +.It 5 Ta Dv SIGTRAP Ta "create core image" Ta "trace trap" +.It 6 Ta Dv SIGABRT Ta "create core image" Ta "abort program" +(formerly +.Dv SIGIOT ) +.It 7 Ta Dv SIGEMT Ta "create core image" Ta "emulate instruction executed" +.It 8 Ta Dv SIGFPE Ta "create core image" Ta "floating-point exception" +.It 9 Ta Dv SIGKILL Ta "terminate process" Ta "kill program" +.It 10 Ta Dv SIGBUS Ta "create core image" Ta "bus error" +.It 11 Ta Dv SIGSEGV Ta "create core image" Ta "segmentation violation" +.It 12 Ta Dv SIGSYS Ta "create core image" Ta "non-existent system call invoked" +.It 13 Ta Dv SIGPIPE Ta "terminate process" Ta "write on a pipe with no reader" +.It 14 Ta Dv SIGALRM Ta "terminate process" Ta "real-time timer expired" +.It 15 Ta Dv SIGTERM Ta "terminate process" Ta "software termination signal" +.It 16 Ta Dv SIGURG Ta "discard signal" Ta "urgent condition present on socket" +.It 17 Ta Dv SIGSTOP Ta "stop process" Ta "stop (cannot be caught or ignored)" +.It 18 Ta Dv SIGTSTP Ta "stop process" Ta "stop signal generated from keyboard" +.It 19 Ta Dv SIGCONT Ta "discard signal" Ta "continue after stop" +.It 20 Ta Dv SIGCHLD Ta "discard signal" Ta "child status has changed" +.It 21 Ta Dv SIGTTIN Ta "stop process" Ta "background read attempted from" +control terminal +.It 22 Ta Dv SIGTTOU Ta "stop process" Ta "background write attempted to" +control terminal +.It 23 Ta Dv SIGIO Ta "discard signal" Ta Tn "I/O" +is possible on a descriptor (see +.Xr fcntl 2 ) +.It 24 Ta Dv SIGXCPU Ta "terminate process" Ta "cpu time limit exceeded (see" +.Xr setrlimit 2 ) +.It 25 Ta Dv SIGXFSZ Ta "terminate process" Ta "file size limit exceeded (see" +.Xr setrlimit 2 ) +.It 26 Ta Dv SIGVTALRM Ta "terminate process" Ta "virtual time alarm (see" +.Xr setitimer 2 ) +.It 27 Ta Dv SIGPROF Ta "terminate process" Ta "profiling timer alarm (see" +.Xr setitimer 2 ) +.It 28 Ta Dv SIGWINCH Ta "discard signal" Ta "Window size change" +.It 29 Ta Dv SIGINFO Ta "discard signal" Ta "status request from keyboard" +.It 30 Ta Dv SIGUSR1 Ta "terminate process" Ta "User defined signal 1" +.It 31 Ta Dv SIGUSR2 Ta "terminate process" Ta "User defined signal 2" +.El +.Pp +The +.Fa sig +argument specifies which signal was received. +The +.Fa func +procedure allows a user to choose the action upon receipt of a signal. +To set the default action of the signal to occur as listed above, +.Fa func +should be +.Dv SIG_DFL . +A +.Dv SIG_DFL +resets the default action. +To ignore the signal, +.Fa func +should be +.Dv SIG_IGN . +This will cause subsequent instances of the signal to be ignored +and pending instances to be discarded. +If +.Dv SIG_IGN +is not used, +further occurrences of the signal are +automatically blocked and +.Fa func +is called. +.Pp +The handled signal is unblocked when the +function returns and +the process continues from where it left off when the signal occurred. +.Bf -symbolic +Unlike previous signal facilities, the handler +func() remains installed after a signal has been delivered. +.Ef +.Pp +For some system calls, if a signal is caught while the call is +executing and the call is prematurely terminated, +the call is automatically restarted. +Any handler installed with +.Xr signal 3 +will have the +.Dv SA_RESTART +flag set, meaning that any restartable system call will not return on +receipt of a signal. +The affected system calls include +.Xr read 2 , +.Xr write 2 , +.Xr sendto 2 , +.Xr recvfrom 2 , +.Xr sendmsg 2 , +and +.Xr recvmsg 2 +on a communications channel or a low speed device +and during a +.Xr ioctl 2 +or +.Xr wait 2 . +However, calls that have already committed are not restarted, +but instead return a partial success (for example, a short read count). +These semantics could be changed with +.Xr siginterrupt 3 . +.Pp +When a process which has installed signal handlers forks, +the child process inherits the signals. +All caught signals may be reset to their default action by a call +to the +.Xr execve 2 +function;

utmpx * +.Fn pututxline "const struct utmpx *utx" +.Ft void +.Fn setutxent void +.Sh DESCRIPTION +These functions provide access to the +.Xr utmpx 5 +user accounting database. +.Pp +.Fn getutxent +reads the next entry from the database; +if the database was not yet open, it also opens it. +.Fn setutxent +resets the database, so that the next +.Fn getutxent +call will get the first entry. +.Fn endutxent +closes the database. +.Pp +.Fn getutxid +returns the next entry of the type specified in its argument's +.Va ut_type +field, or +.Dv NULL +if none is found. +.Fn getutxline +returns the next +.Dv LOGIN_PROCESS +or +.Dv USER_PROCESS +entry which has the same name as specified in the +.Va ut_line +field, or +.Dv NULL +if no match is found. +.Pp +.Fn pututxline +adds the argument +.Xr utmpx 5 +entry line to the accounting database, replacing a previous entry for +the same user if it exists. +Only the superuser may write to the accounting database. +.Ss The utmpx structure +The +.Nm utmpx +structure has the following definition: +.Pp +.Bd -literal +struct utmpx { + char ut_user[_UTX_USERSIZE]; /* login name */ + char ut_id[_UTX_IDSIZE]; /* id */ + char ut_line[_UTX_LINESIZE]; /* tty name */ + pid_t ut_pid; /* process id creating the entry */ + short ut_type; /* type of this entry */ + struct timeval ut_tv; /* time entry was created */ + char ut_host[_UTX_HOSTSIZE]; /* host name */ + __uint32_t ut_pad[16]; /* reserved for future use */ +}; +.Ed +.Pp +Valid entries for +.Fa ut_type +are: +.Bl -tag -width ".Dv LOGIN_PROCESSXX" -compact -offset indent +.It Dv BOOT_TIME +Time of a system boot. +.It Dv DEAD_PROCESS +A session leader exited. +.It Dv EMPTY +No valid user accounting information. +.It Dv INIT_PROCESS +A process spawned by +.Xr init 8 . +.It Dv LOGIN_PROCESS +The session leader of a logged-in user. +.It Dv NEW_TIME +Time after system clock change. +.It Dv OLD_TIME +Time before system clock change. +.It Dv RUN_LVL +Run level. +Provided for compatibility, not used. +.It Dv USER_PROCESS +A user process. +.It Dv SHUTDOWN_TIME +Time of system shutdown (extension to the standards). +.El +.Pp +For each value of +.Fa ut_type , +the other fields with meaningful values are as follows: +.Bl -tag -width ".Dv LOGIN_PROCESSXX" -compact -offset indent +.It Dv BOOT_TIME +.Fa ut_tv +.It Dv DEAD_PROCESS +.Fa ut_id , +.Fa ut_pid , +.Fa ut_tv +.It Dv EMPTY +(no others) +.It Dv INIT_PROCESS +.Fa ut_id , +.Fa ut_pid , +.Fa ut_tv +.It Dv LOGIN_PROCESS +.Fa ut_id , +.Fa ut_user +(implementation-defined name of the login process), +.Fa ut_pid , +.Fa ut_tv +.It Dv NEW_TIME +.Fa ut_tv +.It Dv OLD_TIME +.Fa ut_tv +.It Dv RUN_LVL +(no used) +.It Dv USER_PROCESS +.Fa ut_id , +.Fa ut_user +(login name of the user), +.Fa ut_line , +.Fa ut_pid , +.Fa ut_host +(hostname of remote user) +.Fa ut_tv +.It Dv SHUTDOWN_TIME +.Fa ut_tv +.El +.Ss Other extensions to the standards +The +.Fa ut_type +value may also be OR-ed with the following masks: +.Bl -tag -width XXXX -compact -offset indent +.It Dv UTMPX_AUTOFILL_MASK +Depending on the main part of +.Fa ut_type +value, other fields are automatically filled in (as specified in the +meaningful fields table above). +In particular, the +.Fa ut_id +field will be set using the convention of the last four characters of the +.Fa ut_line +field (itself filled in automatically from the tty name of the device connected +to the standard input, output or error, whichever is available). +Note that it is more efficient to fill in as many values as are already +available beforehand, rather than have then automatically filled in. +.It Dv UTMPX_DEAD_IF_CORRESPONDING_MASK +When +.Fa ut_type +value is +.Dv DEAD_PROCESS, a call to +.Fn pututxline +will succeed only if a corresponding entry already exists with a +.Fa ut_type +value of +.Dv USER_PROCESS . +.El +.Pp +Note that the above mask values do not show up in any file format, or in +any subsequent reads of the data. +.Pp +To support +.Pa wtmpx +and +.Pa lastlogx +equivalent capability, +.Fn pututxline +automatically writes to the appropriate files. +Additional APIs to read these files is available in +.Xr endutxent_wtmp 3 +and +.Xr getlastlogx 3 . +.Ss Backward compatibility +Successful calls to +.Fn pututxline +will automatically write equivalent entries into the +.Pa utmp , +.Pa wtmp +and +.Pa lastlog +files. +Programs that read these old files should work as expected. +However, directly writing to these files does not make corresponding +entries in +.Pa utmpx +and the +.Pa wtmpx +and +.Pa lastlogx +equivalent files, so such write-access is deprecated. +.Sh RETURN VALUES +.Fn getutxent +returns the next entry, or +.Dv NULL +on failure (end of database or problems reading from the database). +.Fn getutxid +and +.Fn getutxline +return the matching structure on success, or +.Dv NULL +if no match was found. +.Pp +.Fn pututxline +returns the structure that was successfully written, or +.Dv NULL +is returned and the global variable +.Va errno +is set to indicate the error. +.Sh ERRORS +No errors are defined for the +.Fn endutxent , +.Fn getutxent , +.Fn getutxid , +.Fn getutxline , +and +.Fn setutxent +functions. +.Pp +The +.Fn pututxline +function may fail if: +.Bl -tag -width Er +.It Bq Er EPERM +The process does not have appropriate privileges. +.It Bq Er EINVAL +The +.Dv UTMPX_DEAD_IF_CORRESPONDING_MASK +flags was specified along with +.Dv DEAD_PROCESS , +but no corresponding entry with +.Dv USER_PROCESS +was found. +.El +.Pp +Other errors may be returned if +.Dv UTMPX_AUTOFILL_MASK +was specified, and a field could not be auto-filled. +.Sh SEE ALSO +.Xr endutxent_wtmp 3 , +.Xr getlastlogx 3 , +.Xr utmpx 5 +.Sh STANDARDS +The +.Fn endutxent , +.Fn getutxent , +.Fn getutxid , +.Fn getutxline ,

One + * representation is to store one bit per byte in an array of bytes. Bit N of + * the NBS spec is stored as the LSB of the Nth byte (index N-1) in the array. + * Another representation stores the 64 bits in 8 bytes, with bits 1..8 in the + * first byte, 9..16 in the second, and so on. The DES spec apparently has + * bit 1 in the MSB of the first byte, but that is particularly noxious so we + * bit-reverse each byte so that bit 1 is the LSB of the first byte, bit 8 is + * the MSB of the first byte. Specifically, the 64-bit input data and key are + * converted to LSB format, and the output 64-bit block is converted back into + * MSB format. + * + * DES operates internally on groups of 32 bits which are expanded to 48 bits + * by permutation E and shrunk back to 32 bits by the S boxes. To speed up + * the computation, the expansion is applied only once, the expanded + * representation is maintained during the encryption, and a compression + * permutation is applied only at the end. To speed up the S-box lookups, + * the 48 bits are maintained as eight 6 bit groups, one per byte, which + * directly feed the eight S-boxes. Within each byte, the 6 bits are the + * most significant ones. The low two bits of each byte are zero. (Thus, + * bit 1 of the 48 bit E expansion is stored as the "4"-valued bit of the + * first byte in the eight byte representation, bit 2 of the 48 bit value is + * the "8"-valued bit, and so on.) In fact, a combined "SPE"-box lookup is + * used, in which the output is the 64 bit result of an S-box lookup which + * has been permuted by P and expanded by E, and is ready for use in the next + * iteration. Two 32-bit wide tables, SPE[0] and SPE[1], are used for this + * lookup. Since each byte in the 48 bit path is a multiple of four, indexed + * lookup of SPE[0] and SPE[1] is simple and fast. The key schedule and + * "salt" are also converted to this 8*(6+2) format. The SPE table size is + * 8*64*8 = 4K bytes. + * + * To speed up bit-parallel operations (such as XOR), the 8 byte + * representation is "union"ed with 32 bit values "i0" and "i1", and, on + * machines which support it, a 64 bit value "b64". This data structure, + * "C_block", has two problems. First, alignment restrictions must be + * honored. Second, the byte-order (e.g. little-endian or big-endian) of + * the architecture becomes visible. + * + * The byte-order problem is unfortunate, since on the one hand it is good + * to have a machine-independent C_block representation (bits 1..8 in the + * first byte, etc.), and on the other hand it is good for the LSB of the + * first byte to be the LSB of i0. We cannot have both these things, so we + * currently use the "little-endian" representation and avoid any multi-byte + * operations that depend on byte order. This largely precludes use of the + * 64-bit datatype since the relative order of i0 and i1 are unknown. It + * also inhibits grouping the SPE table to look up 12 bits at a time. (The + * 12 bits can be stored in a 16-bit field with 3 low-order zeroes and 1 + * high-order zero, providing fast indexing into a 64-bit wide SPE.) On the + * other hand, 64-bit datatypes are currently rare, and a 12-bit SPE lookup + * requires a 128 kilobyte table, so perhaps this is not a big loss. + * + * Permutation representation (Jim Gillogly): + * + * A transformation is defined by its effect on each of the 8 bytes of the + * 64-bit input. For each byte we give a 64-bit output that has the bits in + * the input distributed appropriately. The transformation is then the OR + * of the 8 sets of 64-bits. This uses 8*256*8 = 16K bytes of storage for + * each transformation. Unless LARGEDATA is defined, however, a more compact + * table is used which looks up 16 4-bit "chunks" rather than 8 8-bit chunks. + * The smaller table uses 16*16*8 = 2K bytes for each transformation. This + * is slower but tolerable, particularly for password encryption in which + * the SPE transformation is iterated many times. The small tables total 9K + * bytes, the large tables total 72K bytes. + * + * The transformations used are: + * IE3264: MSB->LSB conversion, initial permutation, and expansion. + * This is done by collecting the 32 even-numbered bits and applying + * a 32->64 bit transformation, and then collecting the 32 odd-numbered + * bits and applying the same transformation. Since there are only + * 32 input bits, the IE3264 transformation table is half the size of + * the usual table. + * CF6464: Compression, final permutation, and LSB->MSB conversion. + * This is done by two trivial 48->32 bit compressions to obtain + * a 64-bit block (the bit numbering is given in the "CIFP" table) + * followed by a 64->64 bit "cleanup" transformation. (It would + * be possible to group the bits in the 64-bit block so that 2 + * identical 32->32 bit transformations could be used instead, + * saving a factor of 4 in space and possibly 2 in time, but + * byte-ordering and other complications rear their ugly head. + * Similar opportunities/problems arise in the key schedule + * transforms.) + * PC1ROT: MSB->LSB, PC1 permutation, rotate, and PC2 permutation. + * This admittedly baroque 64->64 bit transformation is used to + * produce the first code (in 8*(6+2) format) of the key schedule. + * PC2ROT[0]: Inverse PC2 permutation, rotate, and PC2 permutation. + * It would be possible to define 15 more transformations, each + * with a different rotation, to generate the entire key schedule. + * To save space, however, we instead permute each code into the + * next by using a transformation that "undoes" the PC2 permutation, + * rotates the code, and then applies PC2. Unfortunately, PC2 + * transforms 56 bits into 48 bits, dropping 8 bits, so PC2 is not + * invertible. We get around that problem by using a modified PC2 + * which retains the 8 otherwise-lost bits in the unused low-order + * bits of each byte. The low-order bits are cleared when the + * codes are stored into the key schedule. + * PC2ROT[1]: Same as PC2ROT[0], but with two rotations. + * This is faster than applying PC2ROT[0] twice, + * + * The Bell Labs "salt" (Bob Baldwin): + * + * The salting is a simple permutation applied to the 48-bit result of E. + * Specifically, if bit i (1 <= i <= 24) of the salt is set then bits i and + * i+24 of the result are swapped. The salt is thus a 24 bit number, with + * 16777216 possible values. (The original salt was 12 bits and could not + * swap bits 13..24 with 36..48.) + * + * It is possible, but ugly, to warp the SPE table to account for the salt + * permutation. Fortunately, the conditional bit swapping requires only + * about four machine instructions and can be done on-the-fly with about an + * 8% performance penalty. + */ + +typedef union { + unsigned char b[8]; + struct { +#if defined(LONG_IS_32_BITS) + /* long is often faster than a 32-bit bit field */ + long i0; + long i1; +#else + long i0: 32; + long i1: 32; +#endif + } b32; +#if defined(B64) + B64 b64; +#endif +} C_block; + +/* + * Convert twenty-four-bit long in host-order + * to six bits (and 2 low-order zeroes) per char little-endian format. + */ +#define TO_SIX_BIT(rslt, src) { \ + C_block cvt; \ + cvt.b[0] = src; src >>= 6; \ + cvt.b[1] = src; src >>= 6; \ + cvt.b[2] = src; src >>= 6; \ + cvt.b[3] = src; \ + rslt = (cvt.b32.i0 & 0x3f3f3f3fL) << 2; \ + } + +/* + * These macros may someday permit efficient use of 64-bit integers. + */ +#define ZERO(d,d0,d1) d0 = 0, d1 = 0 +#define LOAD(d,d0,d1,bl) d0 = (bl).b32.i0, d1 = (bl).b32.i1 +#define LOADREG(d,d0,d1,s,s0,s1) d0 = s0, d1 = s1 +#define OR(d,d0,d1,bl) d0 |= (bl).b32.i0, d1 |= (bl).b32.i1 +#define STORE(s,s0,s1,bl) (bl).b32.i0 = s0, (bl).b32.i1 = s1 +#define DCL_BLOCK(d,d0,d1) long d0, d1 + +#if defined(LARGEDATA) + /* Waste memory like crazy.

fts_open +and +.Fn fts_open_b +functions return a +.Dq handle +on a file hierarchy, which is then supplied to +the other +.Nm +functions. +The function +.Fn fts_read +returns a pointer to a structure describing one of the files in the file +hierarchy. +The function +.Fn fts_children +returns a pointer to a linked list of structures, each of which describes +one of the files contained in a directory in the hierarchy. +In general, directories are visited two distinguishable times; in pre-order +(before any of their descendants are visited) and in post-order (after all +of their descendants have been visited). +Files are visited once. +It is possible to walk the hierarchy +.Dq logically +(ignoring symbolic links) +or physically (visiting symbolic links), order the walk of the hierarchy or +prune and/or re-visit portions of the hierarchy. +.Pp +Two structures are defined (and typedef'd) in the include file +.Aq Pa fts.h . +The first is +.Fa FTS , +the structure that represents the file hierarchy itself. +The second is +.Fa FTSENT , +the structure that represents a file in the file +hierarchy. +Normally, an +.Fa FTSENT +structure is returned for every file in the file +hierarchy. +In this manual page, +.Dq file +and +.Dq Fa FTSENT No structure +are generally +interchangeable. +The +.Fa FTSENT +structure contains at least the following fields, which are +described in greater detail below: +.Bd -literal +typedef struct _ftsent { + u_short fts_info; /* flags for FTSENT structure */ + char *fts_accpath; /* access path */ + char *fts_path; /* root path */ + u_short fts_pathlen; /* strlen(fts_path) */ + char *fts_name; /* file name */ + u_short fts_namelen; /* strlen(fts_name) */ + short fts_level; /* depth (\-1 to N) */ + int fts_errno; /* file

"fts_namelen" +.It Fa fts_info +One of the following values describing the returned +.Fa FTSENT +structure and +the file it represents. +With the exception of directories without errors +.Pq Dv FTS_D , +all of these +entries are terminal, that is, they will not be revisited, nor will any +of their descendants be visited. +.Bl -tag -width FTS_DEFAULT +.It Dv FTS_D +A directory being visited in pre-order. +.It Dv FTS_DC +A directory that causes a cycle in the tree. +(The +.Fa fts_cycle +field of the +.Fa FTSENT +structure will be filled in as well.) +.It Dv FTS_DEFAULT +Any +.Fa FTSENT +structure that represents a file type not explicitly described +by one of the other +.Fa fts_info +values. +.It Dv FTS_DNR +A directory which cannot be read. +This is an error return, and the +.Fa fts_errno +field will be set to indicate what caused the error. +.It Dv FTS_DOT +A file named +.Ql .\& +or +.Ql ..\& +which was not specified as a file name to +.Fn fts_open +or +.Fn fts_open_b +(see +.Dv FTS_SEEDOT ) . +.It Dv FTS_DP +A directory being visited in post-order. +The contents of the +.Fa FTSENT +structure will be unchanged from when +it was returned in pre-order, i.e. with the +.Fa fts_info +field set to +.Dv FTS_D . +.It Dv FTS_ERR +This is an error return, and the +.Fa fts_errno +field will be set to indicate what caused the error. +.It Dv FTS_F +A regular file. +.It Dv FTS_NS +A file for which no +.Xr stat 2 +information was available. +The contents of the +.Fa fts_statp +field are undefined. +This is an error return, and the +.Fa fts_errno +field will be set to indicate what caused the error. +.It Dv FTS_NSOK +A file for which no +.Xr stat 2 +information was requested. +The contents of the +.Fa fts_statp +field are undefined. +.It Dv FTS_SL +A symbolic link. +.It Dv FTS_SLNONE +A symbolic link with a non-existent target. +The contents of the +.Fa fts_statp +field reference the file characteristic information for the symbolic link +itself. +.El +.It Fa fts_accpath +A path for accessing the file from the current directory. +.It Fa fts_path +The path for the file relative to the root of the traversal. +This path contains the path specified to +.Fn fts_open +or +.Fn fts_open_b +as a prefix. +.It Fa fts_pathlen +The length of the string referenced by +.Fa fts_path . +.It Fa fts_name +The name of the file. +.It Fa fts_namelen +The length of the string referenced by +.Fa fts_name . +.It Fa fts_level +The depth of the traversal, numbered from \-1 to N, where this file +was found. +The +.Fa FTSENT +structure representing the parent of the starting point (or root) +of the traversal is numbered +.Dv FTS_ROOTPARENTLEVEL +(\-1), and the +.Fa FTSENT +structure for the root +itself is numbered +.Dv FTS_ROOTLEVEL +(0). +.It Fa fts_errno +Upon return of a +.Fa FTSENT +structure from the +.Fn fts_children +or +.Fn fts_read +functions, with its +.Fa fts_info +field set to +.Dv FTS_DNR , +.Dv FTS_ERR +or +.Dv FTS_NS , +the +.Fa fts_errno +field contains the value of the external variable +.Va errno +specifying the cause of the error. +Otherwise, the contents of the +.Fa fts_errno +field are undefined. +.It Fa fts_number +This field is provided for the use of the application program and is +not modified by the +.Nm +functions. +It is initialized to 0. +.It Fa fts_pointer +This field is provided for the use of the application program and is +not modified by the +.Nm +functions. +It is initialized to +.Dv NULL . +.It Fa fts_parent +A pointer to the +.Fa FTSENT +structure referencing the file in the hierarchy +immediately above the current file, i.e. the directory of which this +file is a member. +A parent structure for the initial entry point is provided as well, +however, only the +.Fa fts_level , +.Fa fts_number +and +.Fa fts_pointer +fields are guaranteed to be initialized. +.It Fa fts_link +Upon return from the +.Fn fts_children +function, the +.Fa fts_link +field points to the next structure in the NULL-terminated linked list of +directory members. +Otherwise, the contents of the +.Fa fts_link +field are undefined. +.It Fa fts_cycle +If a directory causes a cycle in the hierarchy (see +.Dv FTS_DC ) , +either because +of a hard link between two directories, or a symbolic link pointing to a +directory, the +.Fa fts_cycle +field of the structure will point to the +.Fa FTSENT +structure in the hierarchy that references the same file as the current +.Fa FTSENT +structure. +Otherwise, the contents of the +.Fa fts_cycle +field are undefined. +.It Fa fts_statp +A pointer to +.Xr stat 2 +information for the file. +.El +.Pp +A single buffer is used for all of the paths of all of the files in the +file hierarchy. +Therefore, the +.Fa fts_path +and +.Fa fts_accpath +fields are guaranteed to be +.Dv NUL Ns -terminated +.Em only +for the file most recently returned by +.Fn fts_read . +To use these fields to reference any files represented by other +.Fa FTSENT +structures will require that the path buffer be modified using the +information contained in that +.Fa FTSENT +structure's +.Fa fts_pathlen +field. +Any such modifications should be undone before further calls to +.Fn fts_read +are attempted. +The +.Fa fts_name +field is always +.Dv NUL Ns -terminated . +.Sh FTS_OPEN +The +.Fn fts_open +function takes a pointer to an array of character pointers naming one +or more paths which make up a logical file hierarchy to be traversed. +The array must be terminated by a +.Dv NULL +pointer. +.Pp +There are +a number of options, at least one of which (either +.Dv FTS_LOGICAL +or +.Dv FTS_PHYSICAL ) +must be specified. +The options are selected by +.Em or Ns 'ing +the following values: +.Bl -tag -width "FTS_NOSTAT_TYPE" +.It Dv FTS_COMFOLLOW +This option causes any symbolic link specified as a root path to be +followed immediately whether or not +.Dv FTS_LOGICAL +is also specified. +.It Dv FTS_LOGICAL +This option causes the +.Nm +routines to return +.Fa FTSENT +structures for the targets of symbolic links +instead of the symbolic links themselves. +If this option is set, the only symbolic links for which +.Fa FTSENT +structures +are returned to the application are those referencing non-existent files. +Either +.Dv FTS_LOGICAL +or +.Dv FTS_PHYSICAL +.Em must +be provided to the +.Fn fts_open +function. +.It Dv FTS_NOCHDIR +As a performance optimization, the +.Nm +functions change directories as they walk the file hierarchy. +This has the side-effect that an application cannot rely on being +in any particular directory during the traversal. +The +.Dv FTS_NOCHDIR +option turns off this optimization, and the +.Nm +functions will not change the current directory. +Note that applications should not themselves change their current directory +and try to access files unless +.Dv FTS_NOCHDIR +is specified and absolute +pathnames were provided as arguments to +.Fn fts_open . +.It Dv FTS_NOSTAT +By default, returned +.Fa FTSENT +structures reference file characteristic information (the +.Fa statp +field) for each file visited. +This option relaxes that requirement as a performance optimization, +not calling +.Xr stat 2 +whenever possible. +If +.Xr stat 2 +doesn't need to be called, the +.Nm +functions will set the +.Fa fts_info +field to +.Dv FTS_NSOK ; +otherwise +.Fa fts_info +will be set to the correct file information value corresponding to the +.Xr stat 2 +information. +In any case, the +.Fa statp +field will always be undefined. +Note that because +.Nm +detects directory cycles and dangling symbolic links, +.Xr stat 2 +is always called for directories and is called for symbolic links when +.Dv FTS_LOGICAL +is set. +.It Dv FTS_NOSTAT_TYPE +Like +.Dv FTS_NOSTAT +but if the file type is returned by +.Xr readdir 3 , +the corresponding file information value is returned in +.Fa fts_info +instead of +.Dv FTS_NSOK . +.It Dv FTS_PHYSICAL +This option causes the +.Nm +routines to return +.Fa FTSENT +structures for symbolic links themselves instead +of the target files they point to. +If this option is set, +.Fa FTSENT +structures for all symbolic links in the +hierarchy are returned to the application. +Either +.Dv FTS_LOGICAL +or +.Dv FTS_PHYSICAL +.Em must +be provided to the +.Fn fts_open +function. +.It Dv FTS_SEEDOT +By default, unless they are specified as path arguments to +.Fn fts_open , +any files named +.Ql .\& +or +.Ql ..\& +encountered in the file hierarchy are ignored. +This option causes the +.Nm +routines to return +.Fa FTSENT +structures for them. +.It Dv FTS_XDEV +This option prevents +.Nm +from descending into directories that have a different device number +than the file from which the descent began. +.El +.Pp +The argument +.Fn compar +specifies a user-defined function which may be used to order the traversal +of the hierarchy. +It +takes two pointers to pointers to +.Fa FTSENT +structures as arguments and +should return a negative value, zero, or a positive value to indicate +if the file referenced by its first argument comes before, in any order +with respect to, or after, the file referenced by its second argument. +The +.Fa fts_accpath , +.Fa fts_path +and +.Fa fts_pathlen +fields of the +.Fa FTSENT +structures may +.Em never +be used in this comparison. +If the +.Fa fts_info +field is set to +.Dv FTS_NS +or +.Dv FTS_NSOK , +the +.Fa fts_statp +field may not either. +If the +.Fn compar +argument is +.Dv NULL , +the directory traversal order is in the order listed in +.Fa path_argv +for the root paths, and in the order listed in the directory for +everything else. +.Sh FTS_OPEN_B +The +.Fn fts_open_b +function is like +.Fn fts_open +except +.Fa compar +is a block pointer instead of a function pointer. +This block is passed to +.Xr qsort_b 3 +(whereas +.Fn fts_open +passes its function pointer to +.Xr qsort 3 ) . +.Bd -ragged -offset indent +Note: The +.Fn Block_copy +function (defined in +.In Blocks.h ) +is used by +.Fn fts_open_b +to make a copy of the block, especially for the case when a stack-based +block might go out of scope when the subroutine returns. +.Ed +.Sh FTS_READ +The +.Fn fts_read +function returns a pointer to an +.Fa FTSENT +structure describing a file in +the hierarchy. +Directories (that are readable and do not cause cycles) are visited at +least twice, once in pre-order and once in post-order. +All other files are visited at least once. +(Hard links between directories that do not cause cycles or symbolic +links to symbolic links may cause files to be visited more than once, +or directories more than twice.) +.Pp +If all the members of the hierarchy have been returned, +.Fn fts_read +returns +.Dv NULL +and sets the external variable +.Va errno +to 0. +If an error unrelated to a file in the hierarchy occurs, +.Fn fts_read +returns +.Dv NULL +and sets +.Va errno +appropriately. +If an error related to a returned file occurs, a pointer to an +.Fa FTSENT +structure is returned, and +.Va errno +may or may not have been set (see +.Fa fts_info ) . +.Pp +The +.Fa FTSENT +structures returned by +.Fn fts_read +may be overwritten after a call to +.Fn fts_close +on the same file hierarchy stream, or, after a call to +.Fn fts_read +on the same file hierarchy stream unless they represent a file of type +directory, in which case they will not be overwritten until after a call to +.Fn fts_read +after the +.Fa FTSENT +structure has been returned by the function +.Fn fts_read +in post-order. +.Sh FTS_CHILDREN +The +.Fn fts_children +function returns a pointer to an +.Fa FTSENT +structure describing the first entry in a NULL-terminated linked list of +the files in the directory represented by the +.Fa FTSENT +structure most recently returned by +.Fn fts_read . +The list is linked through the +.Fa fts_link +field of the +.Fa FTSENT +structure, and is ordered by the user-specified comparison function, if any. +Repeated calls to +.Fn fts_children +will recreate this linked list. +.Pp +As a special case, if +.Fn fts_read +has not yet been called for a hierarchy, +.Fn fts_children +will return a pointer to the files in the logical directory specified to +.Fn fts_open , +i.e. the arguments specified to +.Fn fts_open . +Otherwise, if the +.Fa FTSENT +structure most recently returned by +.Fn fts_read +is not a directory being visited in pre-order, +or the directory does not contain any files, +.Fn fts_children +returns +.Dv NULL +and sets +.Va errno +to zero. +If an error occurs, +.Fn fts_children +returns +.Dv NULL +and sets +.Va errno +appropriately. +.Pp +The +.Fa FTSENT +structures returned by +.Fn fts_children +may be overwritten after a call to +.Fn fts_children , +.Fn fts_close +or +.Fn fts_read +on the same file hierarchy stream. +.Pp +.Em Option +may be set to the following value: +.Bl -tag -width FTS_NAMEONLY +.It Dv FTS_NAMEONLY +Only the names of the files are needed. +The contents of all the fields in the returned linked list of structures +are undefined with the exception of the +.Fa fts_name +and +.Fa fts_namelen +fields. +.El +.Sh FTS_SET +The function +.Fn fts_set +allows the user application to determine further processing for the +file +.Fa f +of the stream +.Fa ftsp . +The +.Fn fts_set +function +returns 0 on success, and \-1 if an error occurs. +.Em Option +must be set to one of the following values: +.Bl -tag -width FTS_PHYSICAL +.It Dv FTS_AGAIN +Re-visit the file; any file type may be re-visited. +The next call to +.Fn fts_read +will return the referenced file. +The +.Fa fts_stat +and +.Fa fts_info +fields of the structure will be reinitialized at that time, +but no other fields will have been changed. +This option is meaningful only for the most recently returned +file from +.Fn fts_read . +Normal use is for post-order directory visits, where it causes the +directory to be re-visited (in both pre and post-order) as well as all +of its descendants. +.It Dv FTS_FOLLOW +The referenced file must be a symbolic link. +If the referenced file is the one most recently returned by +.Fn fts_read , +the next call to +.Fn fts_read +returns the file with the +.Fa fts_info +and +.Fa fts_statp +fields reinitialized to reflect the target of the symbolic link instead +of the symbolic link itself. +If the file is one of those most recently returned by +.Fn fts_children , +the +.Fa fts_info +and +.Fa fts_statp +fields of the structure, when returned by +.Fn fts_read , +will reflect the target of the symbolic link instead of the symbolic link +itself. +In either case, if the target of the symbolic link does not exist the +fields of the returned structure will be unchanged and the +.Fa fts_info +field will be set to +.Dv FTS_SLNONE . +.Pp +If the target of the link is a directory, the pre-order return, followed +by the return of all of its descendants, followed by a post-order return, +is done. +.It Dv FTS_SKIP +No descendants of this file are visited. +The file may be one of those most recently returned by either +.Fn fts_children +or +.Fn fts_read . +.El +.Sh FTS_CLOSE +The +.Fn fts_close +function closes a file hierarchy stream +.Fa ftsp +and restores the current directory to the directory from which +.Fn fts_open +was called to open +.Fa ftsp . +The +.Fn fts_close +function +returns 0 on success, and \-1 if an error occurs. +.Sh ERRORS +The function +.Fn fts_open +may fail

The meaning of the codes is +approximately as follows: +.Bl -tag -width "EX_UNAVAILABLEXX(XX)" +.It Sy EX_USAGE Pq 64 +The command was used incorrectly, e.g., with the wrong number of +arguments, a bad flag, a bad syntax in a parameter, or whatever. +.It Sy EX_DATAERR Pq 65 +The input data was incorrect in some way. This should only be used +for user's data and not system files. +.It Sy EX_NOINPUT Pq 66 +An input file (not a system file) did not exist or was not readable. +This could also include errors like +.Dq \&No message +to a mailer (if it cared to catch it). +.It Sy EX_NOUSER Pq 67 +The user specified did not exist. This might be used for mail +addresses or remote logins. +.It Sy EX_NOHOST Pq 68 +The host specified did not exist. This is used in mail addresses or +network requests. +.It Sy EX_UNAVAILABLE Pq 69 +A service is unavailable. This can occur if a support program or file +does not exist. This can also be used as a catchall message when +something you wanted to do doesn't work, but you don't know why. +.It Sy EX_SOFTWARE Pq 70 +An internal software error has been detected.

environment +is made available by +.Xr execve 2 +when a process begins. +By convention these strings have the form +.Dq Ar name=value . +The following names are used by various commands: +.Bl -tag -width LC_MONETARY +.It Ev BLOCKSIZE +The size of the block units used by several commands, most notably +.Xr df 1 , +.Xr du 1 +and +.Xr ls 1 . +This variable is processed by the +.Xr getbsize 3 +function. +.It Ev COLUMNS +The user's preferred width in column positions for the terminal. +Utilities such as +.Xr ls 1 +and +.Xr who 1 +use this to format output into columns. +If unset or empty, utilities will use an +.Xr ioctl 2 +call to ask the terminal driver for the width. +.It Ev EDITOR +Default editor name. +.It Ev EXINIT +A startup list of commands read by +.Xr ex 1 +and +.Xr vi 1 . +.It Ev HOME +A user's login directory, set by +.Xr login 1 +from the password file +.Xr passwd 5 . +.It Ev LANG +This variable configures all programs which use +.Xr setlocale 3 +to use the specified locale unless the +.Ev LC_* +variables are set. +.It Ev LC_ALL +Overrides the values of +.Ev LC_COLLATE , +.Ev LC_CTYPE , +.Ev LC_MESSAGES , +.Ev LC_MONETARY , +.Ev LC_NUMERIC , +.Ev LC_TIME +and +.Ev LANG . +.It Ev LC_COLLATE +Locale to be used for ordering of strings. +.It Ev LC_CTYPE +Locale to be used for character classification +(letter, space, digit, etc.) and for interpreting byte sequences as +multibyte characters. +.It Ev LC_MESSAGES +Locale to be used for diagnostic messages. +.It Ev LC_MONETARY +Locale to be used for interpreting monetary input +and formatting output. +.It Ev LC_NUMERIC +Locale to be used for interpreting numeric input and +formatting output. +.It Ev LC_TIME +Locale to be used for interpreting dates input and +for formatting output. +.It Ev MAIL +The location of the user's +mailbox instead of the default in /var/mail, +used by +.Xr mail 1 , +.Xr sh 1 , +and many other mail clients. +.It Ev NLSPATH +List of directories to be searched for the message catalog referred to by +.Ev LC_MESSAGES . +See +.Xr catopen 3 . +.It Ev PAGER +Default paginator program. +The program specified by this variable is used by +.Xr mail 1 , +.Xr man 1 , +.Xr ftp 1 , +etc, to display information which is longer than the current display. +.It Ev PATH +The sequence of directories, separated by colons, searched by +.Xr csh 1 , +.Xr sh 1 , +.Xr system 3 , +.Xr execvp 3 , +etc, when looking for an executable file. +.Ev PATH +is set to ``/usr/bin:/bin'' initially by +.Xr login 1 . +.It Ev PRINTER +The name of the default printer to be used by +.Xr lpr 1 , +.Xr lpq 1 , +and +.Xr lprm 1 . +.It Ev PWD +The current directory pathname. +.It Ev SHELL +The full pathname of the user's login shell. +.It Ev TERM +The kind of terminal for which output is to be prepared. +This information is used by commands, such as +.Xr nroff 1 +or +.Xr plot 1 +which may exploit special terminal capabilities. +See +.Pa /usr/share/misc/termcap +.Pq Xr termcap 5 +for a list of terminal types. +.It Ev TERMCAP +The string describing the terminal in +.Ev TERM , +or, if +it begins with a '/', the name of the termcap file. +See +.Ev TERMPATH +below, and +.Xr termcap 5 . +.It Ev TERMPATH +A sequence of pathnames of termcap files, separated by colons or spaces, +which are searched for terminal descriptions in the order listed. +Having +no +.Ev TERMPATH +is equivalent to a +.Ev TERMPATH +of +.Dq Pa $HOME/.termcap:/etc/termcap . +.Ev TERMPATH +is ignored if +.Ev TERMCAP +contains a full pathname. +.It Ev TMPDIR +The directory in which to store temporary files. +Most applications use either +.Dq /tmp +or +.Dq /var/tmp . +Setting this variable will make them use another directory. +.It Ev TZ +The timezone to use when displaying dates. +The normal format is a pathname relative to +.Dq Pa /usr/share/zoneinfo . +For example, the command +.Dq env TZ=America/Los_Angeles date +displays the current time in California. +See +.Xr tzset 3 +for more information. +.It Ev USER +The login name of the user. +.El +.Pp +Further names may be placed in the environment by the +.Ic export +command and +.Ar name=value +arguments in +.Xr sh 1 , +or by the +.Ic setenv +command if you use +.Xr csh 1 . +It is unwise to change certain +.Xr sh 1 +variables that are frequently exported by +.Pa .profile +files, such as +.Ev MAIL , +.Ev PS1 , +.Ev PS2 , +and +.Ev IFS , +unless you know what you are doing. +.Pp +The current environment variables can be printed with +.Xr env 1 , +.Xr set 1 +or +.Xr printenv 1 +in +.Xr sh 1 +and +.Xr env 1 , +.Xr printenv 1 +or the +.Cm printenv +built-in command in +.Xr csh 1 . +.Sh PROGRAMMING +Programs can query and modify the environment, using the environment routines +.Xr getenv 3 , +.Xr putenv 3 , +.Xr setenv 3 +and +.Xr unsetenv 3 . +Direct access can be made through the global variable +.Va environ , +though it is recommended that changes to the enviroment still be made through +the environment routines. +.Pp +Shared libraries and bundles don't have direct access to +.Va environ , +which is only available to the loader +.Xr ld 1 +when a complete program is being linked. +The environment routines can still be used, but if direct access to +.Va environ +is needed, the +.Fn _NSGetEnviron +routine, defined in +.In crt_externs.h , +can be used to retrieve the address of +.Va environ +at runtime. +.Sh SEE

All rights reserved. +.Dd 12 January, 2018 +.Dt style 3 +.Os Darwin +.Sh NAME +.Nm style +.Nd C language style guide for Darwin low-level userspace projects +.Sh DESCRIPTION +This style's primary objective is to be as friendly to the code review process +as possible. Therefore, the style aims to ensure that code changes to the +project produce diffs that are +.Pp +.Bl -bullet -compact -offset indent +.It +small +.It +unambiguous +.It +viewable in side-by-side comparison tools +.El +.Pp +As a secondary objective, this style also aims to make code as clear as possible +for an uninitiated programmer reading it. "Clever" syntactic shortcuts are +actively discouraged in favor of code that is easy to understand, even if it is +less concise. Coincidentally, this practice also tends to lend itself to +generating more readable diffs. +.Pp +Like any style, consistent adherence across a project is a virtue in and of +itself, resulting in less distraction for the reader. However, these guidelines +should be taken as exactly that: guidelines. No style can be completely adhered +to all the time. When you have convinced yourself that a deviation from the +style is called for, just make sure it is for the greater good and maintains the +style's aims of minimizing diffs and code complexity. +.Sh GENERAL PRINCIPLES +.Ss Vertical space is a commodity +Scrolling vertically has always been easier than scrolling horizontally. +Computer mouse manufacturers went so far as to dedicate hardware to the task of +scrolling vertically when they came up with scroll wheels. Even on modern +trackpads, while it is possible to scroll horizontally, it is far easier to +scroll vertically. You just flick upwards. Do not be afraid to introduce extra +lines of code if it will result in clearer, more human-parseable diffs when +those lines are changed. +.Ss Horizontal space is precious +Scrolling horizontally is typically awkward, imprecise, and does not lend itself +well toward reading on computers or even in print. (Academic journals frequently +publish with two narrow columns per page to make reading easier, for example.) +Lines should be wrapped consciously; this should not be left to the editor. A +soft-wrapping scheme that looks good in your editor may not look good in someone +else's editor (or with a different configuration for the same editor). +.Pp +Just as natural language comments are difficult to read in one, long line, +so too are lines of code. Both natural languages and programming languages +deserve conscious, deliberate wrapping to improve readability. +.Pp +Wrap at a column width narrow enough to accommodate side-by-side patch +review. 80 is more likely to accommodate this, but 120 might be fine too. Pick a +reasonable column width and stick to it. Think about the lines you are wrapping. +If you have to wrap a line, do so in a way that is clear, and be willing to make +changes to accommodate that (e.g. don't be afraid to declare a variable +separately if having the declaration and assignment on the same line causes it +to wrap in an unclear way). +.Ss Indentation is for scope indication and nothing else +Indentation's sole purpose is to indicate scope. You should not use indentation +to align characters on two lines of source code (beyond, of course, aligning +the first characters of each line if they are both in the same scope). +.Pp +Given this aspect of the style, it does not particularly matter whether the +author chooses spaces or tabs for indentation, and therefore the style makes no +prescription (other than to pick one and stick with it). +.Pp +This style also has another implication: tabs and spaces should never appear +in sequence. Each line will be a series of tabs followed by the first character +of code. Tabs will never appear after the initial indentation of the line. +.Ss Don't require leaving the source to understand it +Always think of future maintainers and document your thought process for them. +Remember, a "future maintainer" might be you after you've forgotten why you did +something. For non-trivial changes, you should not rely on linking to a +ticket-tracking system to provide context and explanation for a piece of code. +You should strive to ensure the reader of your code does not have to +context-switch out of reading it in order to understand it. +.Pp +This is not to say that linking to external resources in code is bad, but +if a change's purpose can be reasonably expressed without interrupting how the +code reads and flows, just do it. You don't need to publish a whitepaper in +comments, but don't just give a link or ticket number with no context. +.Ss Each line of code should minimize entropy +It is actually very difficult to construct a hash comparison scheme that humans +can use without error consistently, and there have been successful social +engineering attacks on getting humans to read two hashes that are "close enough" +as identical. This means that humans need a lot of help telling the difference +between two lines of text. +.Pp +For any expression, divide it up into fundamental atoms (variable declarations, +conditionals, etc.) and then assign each of those atoms to its own line of code. +If you do this, when you change a single atom, it is immediately obvious that +.Em only +that atom changed and nothing else did. The more atoms share lines of code, the +more likely it is that changes to them will generate complex diffs that humans +will have difficulty understanding. +.Ss Don't assume a specific editor +Assume people will be reading your code in a tool that you do not control and +cannot influence. Try viewing your code in such a tool and make sure that it is +understandable. If you follow the guidelines of this style, your code may appear +different in another viewer (in terms of how many columns are required to +display a single line), but its structure will appear identical. +.Sh SPECIFIC GUIDELINES +.Ss Column Width and Line Wrap +80 columns opens the door for a three-way, side-by-side comparison, but it could +be impractical for a number of reasons. 120 columns should provide a nice +balance, but really all that matters is that you pick a width and stick to it. +.Pp +When indenting a continuation line, indent over by two additional tabs. This +visually separates the indented line from the next line, which may itself be +indented. If there is an operator in the middle of the line, the operator should +.Em not +be wrapped to the continuation line. +.Pp +.Em Good +.Bd -literal -offset indent +if (some_condition && some_other_condition && + yet_another_condition) { + exit(0); +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +if (some_condition && some_other_condition && + yet_another_condition) { + exit(0); +} + +if (some_condition && some_other_condition + && yet_another_condition) { + exit(0); +} +.Ed +.Pp +Notice on the good example that the +.Ic exit(0) +line is made obviously distinct from the indented conditions above it. It's very +clear on quick visual inspection that it's not a part of the conditional checks. +The +.Ic && +is left on the first line because, when reviewing a patch to this area, it will +be immediately clear to the reviewer that that line continues to the next one. +.Pp +.Ss Avoid prettifying alignment +Indentation is used only for indicating scope, so no consideration is given to +visual alignment of equal signs, colons, etc. across multiple lines. +.Pp +.Em Good +.Bd -literal -offset indent +typedef enum { + THING0 = 0, + THING1 = 1, + THING_THAT_IS_REALLY_LONG = 2, +} thing_t; +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +enum { + THING0 = 0, + THING1 = 1, + THING_THAT_IS_REALLY_LONG = 2, +}; +.Ed +.Pp +This creates bloated diffs. If you have to re-align a ton of lines after you've +added something longer, you get a bunch of whitespace diffs. So for variable +declarations, enumerations, assignments, etc. just keep every line independent. +.Pp +There is one exception to this rule, and that is if you choose to define a +flagset in terms of its raw hexadecimal values and wish to align them. In this +case, it is a significant benefit to have these values aligned, and you may do +so with spaces. +.Pp +.Em Example +.Bd -literal -offset indent +typedef enum { + F_INIT = 0x00, + F_FOO = 0x01, + F_BARBAZ = 0x02, + F_CAD = 0x04, + F_FAD = 0x08, + F_FUD = 0x10, + F_FLAME = 0x20, + F_FOOD = 0x40, +} flag_t; +.Ed +.Ss Only one blank line at a time +Use blank lines to separate logical chunks of code. Do not use more than one. +.Ss Initialization +C99 has named initializers for structures. Prefer those to initializing members +one-by-one later on. Both structures and arrays should be initialized in the +same style, with each element of the initializer being on its own line. This is +so that when an element is added to or removed from the initialization list, +that change gets its own line of diff. +.Pp +The exception to this is the string literal. +.Pp +.Em Good +.Bd -literal -offset indent +struct my_struct baz = { + .ms_foo = 1, + .ms_bar = NULL, +}; + +char *strings[] = { + "string", + "other string", +}; +.Ed +.Em Bad +.Bd -literal -offset indent +struct my_struct baz = { 1, NULL }; + +struct my_struct baz = { + 1, + NULL +}; + +struct my_struct baz = { .ms_foo = 1, .ms_bar = NULL, }; +.Ed +.Pp +The last element of an initializer list should be followed by a comma. This is +so that when you add a new element to that list, it's a one-line diff rather +rather than a two-line diff (one line of diff to add the +.Ic , +to the previous-last element, and another line of diff to add the new-last +element). +.Pp +.Em Good +.Bd -literal -offset indent +enum { + THING0, + THING1, +}; + +struct my_point p = { + .x = 1, + .y = 0, + .z = 1, +}; +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +enum { + THING0, THING1, +}; + +enum { + THING0, + THING1 +}; + +struct my_point p = { .x = 1, .y = 0, .z = 1 }; +.Ed +.Pp +Note that, if your project requires ANSI C compliance, you should disregard this +guideline, as it will not work under C89. +.Ss Avoid function name overloading +The +.Xr clang 1 +compiler supports extensions to the C language which allow for function name +overloading. Name overloading generally leads to code which is difficult to +read and introspect and should be avoided. +.Ss Prefix `struct` members +Any +.Ic struct +which is shared or exported should have a common prefix for each member. This +helps avoid collisions with preprocessor macros. +.Pp +.Em Good +.Bd -literal -offset indent +struct foobar { + int64_t fb_baz; + char *fb_string; +}; +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +struct foobar { + int64_t baz; + char *string; +}; +.Ed +.Pp +.Ss Types end with `_t` +A type is indicated with +.Ic _t +at the end of the +.Ic typedef , +whether the type refers to a +.Ic struct , +.Ic union , +.Ic enum , +etc. All types are indicated this way. Types are in all lower-case letters. +.Pp +.Em Good +.Bd -literal -offset indent +typedef uint64_t handle_t; +typedef enum foo foo_t; +typedef union bar bar_t; +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +typedef uint64_t Handle; +typedef enum foo foo_e; +typedef union bar bar_u; +.Ed +.Ss Use explicitly-sized integer types +Avoid integer types whose names do not indicate size, such as +.Ic int +or +.Ic long . +Instead, use the types from +.Ic stdint.h +(e.g. +.Ic int64_t , +.Ic uint32_t , +etc.), which explicitly indicate size. You may use size-ambiguous integer types +if an API requires it. +.Ss Use `sizeof()` on variables rather than types where appropriate +The +.Ic sizeof() +operator can take both types and variables as arguments. Where possible and +relevant, always pass a variable. This ensures that if the variable's type +changes, the proper size is used automatically. +.Pp +.Em Good +.Bd -literal -offset indent +uuid_t ident; +memcpy(ident, buff, sizeof(ident)); +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +uuid_t ident; +memcpy(ident, buff, sizeof(uuid_t)); +.Ed +.Pp +.Em IMPORTANT : +When applied to a +.Ic char * , +.Ic sizeof() +will return the width of a pointer, +.Em not +the size of the string literal it points to, so take care to only use +.Xr strlen 3 +for such cases. +.Pp +Relatedly, when applied to an array variable that is a parameter in a function's +parameter list, +.Ic sizeof() +will return the width of a pointer, +.Em not +the size of the type. +.Pp +.Em Good +.Bd -literal -offset indent +char *string = "the quick brown fox"; +size_t len = strlen(string); + +void +foo(uuid_t u) +{ + uuid_t u2; + memcpy(u2, u, sizeof(uuid_t)); +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +char *string = "the quick brown fox"; +size_t len = sizeof(string) - 1; + +void +foo(uuid_t u) +{ + uuid_t u2; + + // sizeof(u) == sizeof(void *) in this context. + memcpy(u2, u, sizeof(u)); +} +.Ed +.Ss Functions which take no parameters have a parameter list of `void` +In C, an empty function parameter list means that +.Em any +set of parameters is acceptable. In virtually all cases where you do this, you +mean to have a parameter list of +.Ic void . +.Pp +.Em Good +.Bd -literal -offset indent +void +foo(void) +{ + do_a_thing_without_arguments(); +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +void +foo() +{ + do_a_thing_without_arguments(); +} +.Ed +.Ss Preprocessor macros +Preprocessor definitions are written in all-caps. Macros which are function-like +may be lower-case provided they do not double-evaluate their arguments. +Function-like macros that do double-evaluate their arguments should be in +all-caps. +.Pp +.Em Good +.Bd -literal -offset indent +#define FOO 1 +#define halt() abort() + +// Does not double-evaluate _a and _b such that max(i++, j) is safe. +#define max(_a, _b) ({ \\ + typeof(_a) a1 = (_a); \\ + typeof(_b) b1 = (_b); \\ + (a1 < b1 ? b1 : a1); \\ +}) + +// Double-evaluates _a and _b, so MAX(i++, j) is not safe. +#define MAX(_a, _b) ((_a) < (_b) ? (_b) : (_a)) +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +#define kFoo 1 + +// Double-evaluates _a and _b. +#define max(_a, _b) ((_a) < (_b) ? (_b) : (_a)) +.Ed +.Pp +Where possible, you should prefer inline functions to preprocessor macros, or +split a macro into a preprocessor piece and an inline function piece. +.Pp +.Em Example +.Bd -literal -offset indent +static inline void +_debug_uint64_impl(const char *name, uint64_t val) +{ + fprintf(stderr, "%s = %llu\\n", name, val); +} + +#define debug_uint64(_v) do { \\ + _debug_uint64_impl(#_v, _v); \\ +} while (0) +.Ed +.Pp +In this example, the preprocessor is used to do something that only the +preprocessor can do: stringify the input variable's name. But once that work is +done, the actual logging of the value is done by an inline function. This keeps +the code much more readable. +.Ss Preprocessor macro parameters should be distinguished +Preprocessor macro expansion can run afoul of naming collisions with other +variables that are in the same scope as the macro being expanded. To help avoid +such collisions, parameters to preprocessor macros should have a prefix, suffix +or both.

If none of your call sites pass +.Ic NULL , +to a pointer parameter, for example, then the a +.Ic NULL +input indicates that there is state corruption in your address space. You may +think that it's good to catch such corruption, but +.Ic NULL +is just +.Em one +possible invalid pointer value. What if the invalid input is +.Ic 0x1 ? +What if it is +.Ic 0x2 ? +Should you also check for those? +.Pp +This kind of input checking complicates code. Because it indicates state +corruption, the only sensible thing to do in that situation would be to abort. +But the operating system has mechanisms in place to detect the reference of an +invalid resource, such as virtual memory and use-after-free detection. There is +no point to you duplicating these mechanisms. +.Pp +Of course, you should always validate inputs +.Em when they come from untrusted external sources +(such as a file or IPC message), but if the inputs only ever comes from your +program, you should trust them. +.Pp +.Em Good +.Bd -literal -offset indent +static foo_t * +get_item(foo_t *arr, size_t idx) +{ + return &arr[idx]; +} + +int +only_call_site(foo_t *f) +{ + foo_t *arr = calloc(10, sizeof(arr[0])); + if (!arr) { + return errno; + } + + *f = get_item(arr, 0); + return 0; +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +static foo_t * +get_item(foo_t *arr, size_t idx) +{ + if (!arr) { + // No point to this check since we'll abort immediately below when we + // try to dereference `arr`.

So your API should validate input from its caller +and abort on invalid input. Returning an error in such a case is pointless, +since the caller probably isn't checking the return code anyway. The only sure +way to get the programmer's attention is to abort the calling process with a +helpful message. The +.Ic os_crash +routine allows you to supply such a message that the crash reporter on Darwin +will display in its crash report. +.Pp +.Em Good +.Bd -literal -offset indent +uint8_t +foo_a_bar(uint8_t number) +{ + if (number > (UINT8_MAX / 2)) { + os_crash("number given to foo_a_bar() too large"); + } + return (number * 2); +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +int +foo_a_bar(uint8_t number, uint8_t *new_number) +{ + if (number > (UINT8_MAX / 2)) { + return EINVAL; + } + *new_number = (number * 2); + return 0; +} +.Ed +.Ss Don't mingle POSIX return codes and errors +Some POSIX routines have return values that indicate whether you should check +.Ic errno , +and others just return the error directly. While POSIX generally documents what +does what pretty well, there are lots of SPIs scattered around the system that +use both conventions and aren't documented at all, leaving you to spelunk +through the implementation to find out what's what. +.Pp +To avoid confusion, do not re-use the same variable for the return codes from +these functions. If an API returns a code indicating that you should check +.Ic errno , +name it +.Ic ret +or similar. If it returns the error directly, name it +.Ic error +or similar and make it of type +.Ic errno_t . +This makes it very clear to the person reading the code that you did the work to +find out how the API worked. By naming the variable you store the return value +in appropriately, a reader of your code (possibly Future You) can immediately +know what's going on. +.Pp +If you are making new API or SPI that returns an error code, make it return +.Ic errno_t +and do not use the global +.Ic errno +for communicating error information. +.Pp +.Em Good +.Bd -literal -offset indent +#include + +errno_t error = posix_spawn(NULL, "ls", NULL, NULL, argv, envp); +switch (error) { +case 0: + // Handle success. + break; +case EACCES: + // Handle "permission denied". + break; +} + +int ret = reboot(RB_AUTOBOOT); +if (ret == -1) { + switch (errno) { + case EPERM: + // Handle "permission denied". + break; + case EBUSY: + // Handle "reboot already in progress". + break; + } +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +int ret = posix_spawn(NULL, "ls", NULL, NULL, argv, envp); +switch (error) { +case 0: + // Handle success. + break; +case EACCES: + // Handle "permission denied". + break; +} + +int error = reboot(RB_AUTOBOOT); +if (error == -1) { + switch (errno) { + case EPERM: + // Handle "permission denied". + break; + case EBUSY: + // Handle "reboot already in progress". + break; + } +} +.Ed +.Ss Avoid complex `if` statements and return distinct error codes +Breaking up a single complex +.Ic if +statement +into multiple distinct checks is both more readable and makes it possible to be +more granular about handling failure cases. It also leads to smaller diffs if +one of those conditions turns out to require special handling. +.Pp +Complex +.Ic if +statements are often associated with input validation and just returning an +error code (usually +.Ic EINVAL ) +if any input is invalid. While deciding which error to return in which case is +more of an art than a science, that doesn't mean you should just give up and +return a single error every time there isn't an immediately obvious fit to the +case you've encountered. +.Pp +Ideally, every case where your routine may fail should be represented by a +distinct error code, but this is often not practical. Still, you should attempt +to distinguish each +.Em likely +failure case with its own error code. The POSIX error space is fairly rich, and +error descriptions are brief enough that they can be liberally interpreted. For +example, +.Ic ESRCH +can be used to apply to any situation where a resource could not be located, not +just conditions where there is literally "No such process". +.Pp +This isn't to say that you should never have compound conditions in an +.Ic if +statement, but the groupings should almost always be small, and the grouped +checks should be highly likely to require change as a group when change is +needed. +.Pp +.Em Good +.Bd -literal -offset indent +if (foo->f_int > 10 || foo->f_int < 5) + return ERANGE; +} + +if (!foo->f_uaddr) { + return EFAULT; +} + +if (foo->f_has_idx && foo->f_idx > 100) { + return ERANGE; +} + +if (foo->f_state != FS_INITIALIZED) { + return EBUSY; +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +if (foo->f_int > 10 || foo->f_int < 5 || !foo->f_uaddr || (foo->f_has_idx && foo->f_idx > 100) || + foo->f_state != FS_INITIALIZED) { + return EINVAL; +} +.Ed +.Pp +See +.Xr intro 2 , +.Ic , +and +.Ic +for the error codes supported on Darwin. +.Ss Don't NULL-check when calling `free(3)` +.Ic NULL +is valid input to +.Xr free 3 . +It's part of the API contract.

Append a suffix to these SPIs +to indicate their bespokeness and the intended caller with +.Ic _4caller . +For example, if you add an SPI specifically for IOKit, your suffix would likely +be +.Ic _4IOKit . +.Ss Use `#if` instead of `#ifdef` where appropriate +.Ic #ifdef +is to check if a token is +.Em defined at all to anything. +.Ic #if +is to check the token's value. The C standard specifies that when a token is +undefined, +.Ic #if +will evaluate it as +.Ic 0 . +When checking for features, it's almost always more appropriate to use +.Ic #if +since the lack of a feature could still be communicated by setting the token's +value to +.Ic 0 , +which would pass the +.Ic #ifdef +check. +.Ss Use Function Attributes from `` +If you're on Darwin, +.Ic libplatform +defines a lot of nice macros for compiler attributes. Use them to decorate your +functions. This gives the compiler lots more information so it can do fancy +optimizations. Things like +.Ic OS_NONNULL +let the compiler know that a parameter should never be +.Ic NULL . +.Ic OS_WARN_RESULT +is great for enforcing that a caller always check the return value of a +function. +.Pp +.Ic OS_MALLOC +lets the compiler know that the function returns a heap allocation, and +.Ic OS_OBJECT_RETURNS_RETAINED +lets ARC know that the function returns an object with a reference that the +caller is responsible for releasing. +.Pp +You can avoid having to decorate all your pointer parameters by using +.Ic OS_ASSUME_NONNULL_BEGIN +and +.Ic OS_ASSUME_NONNULL_END +and specifically annotating variables which +.Em can +be +.Ic NULL +with the +.Ic _Nullable +keyword. Either approach is acceptable. +.Pp +Generally, use these attributes on functions which will have callers who cannot +view the implementation. Putting many of these attributes on (for example) an +inline function is harmless, but the compiler can reason about things like +.Ic OS_NONNULL +and infer it when it can view the implementation at all call sites. +.Pp +So as a rule of thumb, if it's in a header, decorate it appropriately. These +attributes can also serve as nice implicit documentation around API and SPI. For +example, if you have a decoration of +.Ic OS_NONNULL1 , +you don't have to spell out in the HeaderDoc that you can't pass +.Ic NULL +for that parameter; it'll be right there in the declaration, and the compiler +will catch attempts to do so. +.Ss Distinguish C function definitions from declarations +In C, make the definition of a function findable and distinguishable from its +declaration (if any) through regular expressions. This way, you can find the +implementation of +.Ic foo +by doing a regex search for +.Ic ^foo , +and you won't get the declaration as a result. +.Pp +.Em Good +.Bd -literal -offset indent +static int foo(int bar); + +int +foo(int bar) +{ + return bar; +} +.Ed +.Pp +.Em Bad +.Bd -literal -offset indent +static int foo(int bar); + +int foo(int bar) +{ + return bar; +} +.Ed +.Pp +This has the additional benefit of allowing you to change the name/parameter +list of a function independently of the return type.

presently valid for +.Dv AF_INET +and +.Dv AF_INET6 . +.Pp +The +.Fn inet_aton +routine interprets the specified character string as an Internet address, +placing the address into the structure provided. +It returns 1 if the string was successfully interpreted, +or 0 if the string is invalid. +The +.Fn inet_addr +and +.Fn inet_network +functions return numbers suitable for use +as Internet addresses and Internet network +numbers, respectively. +.Pp +The function +.Fn inet_ntop +converts an address +.Fa *src +from network format +(usually a +.Ft struct in_addr +or some other binary form, in network byte order) to presentation format +(suitable for external display purposes). +The +.Fa size +argument specifies the size, in bytes, of the buffer +.Fa *dst . +.Dv INET_ADDRSTRLEN +and +.Dv INET6_ADDRSTRLEN +define the maximum size required to convert an address of the respective +type. +It returns NULL if a system error occurs (in which case, +.Va errno +will have been set), or it returns a pointer to the destination string. +This function is presently valid for +.Dv AF_INET +and +.Dv AF_INET6 . +.Pp +The routine +.Fn inet_ntoa +takes an Internet address and returns an +.Tn ASCII +string representing the address in +.Ql .\& +notation. +The routine +.Fn inet_makeaddr +takes an Internet network number and a local +network address and constructs an Internet address +from it. +The routines +.Fn inet_netof +and +.Fn inet_lnaof +break apart Internet host addresses, returning +the network number and local network address part, +respectively. +.Pp +All Internet addresses are returned in network +order (bytes ordered from left to right). +All network numbers and local address parts are +returned as machine byte order integer values. +.Sh INTERNET ADDRESSES +Values specified using the +.Ql .\& +notation take one +of the following forms: +.Bd -literal -offset indent +a.b.c.d +a.b.c +a.b +a +.Ed +.Pp +When four parts are specified, each is interpreted +as a byte of data and assigned, from left to right, +to the four bytes of an Internet address. +Note +that when an Internet address is viewed as a 32-bit +integer quantity on the +.Tn VAX +the bytes referred to +above appear as +.Dq Li d.c.b.a . +That is, +.Tn VAX +bytes are +ordered from right to left. +.Pp +When a three part address is specified, the last +part is interpreted as a 16-bit quantity and placed +in the right-most two bytes of the network address. +This makes the three part address format convenient +for specifying Class B network addresses as +.Dq Li 128.net.host . +.Pp +When a two

"uint32_t numsrc" +.Fa "struct sockaddr_storage *slist" +.Fc +.Sh DESCRIPTION +The +.Nm +functions implement the advanced, full-state multicast API +defined in RFC 3678. +An application may use these functions to atomically set and +retrieve the multicast source address filters associated with a socket +.Fa s +and a multicast +.Fa group . +.Pp +The functions +.Fn getipv4sourcefilter +and +.Fn getsourcefilter +allow an application to discover the filter mode, and +source filter entries, +for an existing group membership. +.Pp +The kernel will always return the number of source filter +entries on the socket for that group in +.Fa *numsrc . +If the +.Fa *numsrc +argument is non-zero, the kernel will attempt to return up to +.Fa *numsrc +filter entries in the array pointed to by +.Fa slist . +The +.Fa *numsrc +argument may be set to 0, in which case the +.Fa slist +argument will be ignored. +.Pp +For the +.Fn setipv4sourcefilter +and +.Fn setsourcefilter +functions, +the +.Fa fmode +argument may be used to place the socket into inclusive or exclusive +group membership modes, by using the +.Dv MCAST_INCLUDE +or +.Dv MCAST_EXCLUDE +constants respectively. +The +.Fa numsrc +argument specifies the number of source entries in the +.Fa slist +array. +If the +.Fa numsrc +argument has a value of 0, +all source filters will be removed from the socket. +Removing all source filters from a membership which is in the +.Dv MCAST_INCLUDE +filter mode will cause the group to be left on that socket. +.Pp +The protocol-independent function +.Fn setsourcefilter +allows an application to join a multicast group on an interface +which may not have an assigned protocol address, +by passing its index for the +.Fa interface +argument. +.Pp +Any changes made by these functions +will be communicated to IGMPv3 and/or MLDv2 routers +on the local network as appropriate. +If no IGMPv3 or MLDv2 routers are present, changes in the source filter +lists made by these functions will not cause +state changes to be transmitted, with the exception of any +change which causes a group to be joined or left. +The kernel will continue to maintain the source filter state +regardless of the IGMP or MLD version in use on the link. +.Sh IMPLEMENTATION NOTES +The IPv4 specific versions of these functions are implemented in terms +of the protocol-independent functions. +Application writers are encouraged to use the protocol-independent functions +for efficiency, and forwards compatibility with IPv6 networks. +.Pp +For the protocol-independent functions +.Fn getsourcefilter +and +.Fn setsourcefilter , +the argument +.Fa grouplen +argument specifies the size of the structure pointed to by +.Fa group . +This is required in order to differentiate between different +address families. +.Pp +Currently +.Fx +does not support source address selection for the IPv4 +protocol family, therefore the use of multicast APIs with +an unnumbered IPv4 interface is +.Em not recommended. +In all cases, the first assigned IPv4 address on the interface +will be used as the source address of IGMP control traffic. +If this address is removed or changed, the results are undefined. +.Sh RETURN VALUES +.Rv -std getsourcefilter getipv4sourcefilter setsourcefilter setipv4sourcefilter +.Sh ERRORS +The +.Nm +functions may fail because of: +.Bl -tag -width Er +.It Bq Er

The tests at the end of +the tests file have accordingly been uncommented. The primary sign of +the bug was that something like a?b matching ab matched b rather than ab. +(The bug was essentially specific to this exact situation, else it would +have shown up earlier.) + +New in alpha3.3: The definition of word boundaries has been altered +slightly, to more closely match the usual programming notion that "_" +is an alphabetic. Stuff used for pre-ANSI systems is now in a subdir, +and the makefile no longer alludes to it in mysterious ways. The +makefile has generally been cleaned up some. Fixes have been made +(again!) so that the regression test will run without -DREDEBUG, at +the cost of weaker checking. A workaround for a bug in some folks' + has been added. And some more things have been added to +tests, including a couple right at the end which are commented out +because the code currently flunks them (complex bug; fix coming). +Plus the usual minor cleanup. + +New in alpha3.2: Assorted bits of cleanup and portability improvement +(the development base is now a BSDI system using GCC instead of an ancient +Sun system, and the newer compiler exposed some glitches). Fix for a +serious bug that affected REs using many [] (including REG_ICASE REs +because of the way they are implemented), *sometimes*, depending on +memory-allocation patterns. The header-file prototypes no longer name +the parameters, avoiding possible name conflicts. The possibility that +some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is +now handled gracefully. "uchar" is no longer used as an internal type +name (too many people have the same idea). Still the same old lousy +performance, alas. + +New in alpha3.1: Basically nothing, this release is just a bookkeeping +convenience. Stay tuned. + +New in alpha3.0: Performance is no better, alas, but some fixes have been +made and some functionality has been added. (This is basically the "get +it out the door in time for 4.4" release.) One bug fix: regfree() didn't +free the main internal structure (how embarrassing). It is now possible +to put NULs in either the RE or the target string, using (resp.) a new +REG_PEND flag and the old REG_STARTEND flag. The REG_NOSPEC flag to +regcomp() makes all characters ordinary, so you can match a literal +string easily (this will become more useful when performance improves!). +There are now primitives to match beginnings and ends of words, although +the syntax is disgusting and so is the implementation. The REG_ATOI +debugging interface has changed a bit. And there has been considerable +internal cleanup of various kinds. + +New in alpha2.3: Split change list out of README, and moved flags notes +into Makefile. Macro-ized the name of regex(7) in regex(3), since it has +to change for 4.4BSD. Cleanup work in engine.c, and some new regression +tests to catch tricky cases thereof. + +New in alpha2.2: Out-of-date manpages updated. Regerror() acquires two +small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges +in my own test program and might be useful to others for similar purposes. +The regression test will now compile (and run) without REDEBUG. The +BRE \$ bug is fixed. Most uses of "uchar" are gone; it's all chars now. +Char/uchar parameters are now written int/unsigned, to avoid possible +portability problems with unpromoted parameters. Some unsigned casts have +been introduced to minimize portability problems with shifting into sign +bits. + +New in alpha2.1: Lots of little stuff, cleanup and fixes. The one big +thing is that regex.h is now generated, using mkh, rather than being +supplied in the distribution; due to circularities in dependencies, +you have to build regex.h explicitly by "make h". The two known bugs +have been fixed (and the regression test now checks for them), as has a +problem with assertions not being suppressed in the absence of REDEBUG. +No performance work yet. + +New in alpha2: Backslash-anything is an ordinary character, not an +error (except, of course, for the handful of backslashed metacharacters +in BREs), which should reduce script breakage. The regression test +checks *where* null strings are supposed to match, and has generally +been tightened up somewhat. Small bug fixes in parameter passing (not +harmful, but technically errors) and some other areas. Debugging +invoked by defining REDEBUG rather than not defining NDEBUG. + +New in alpha+3: full prototyping for internal routines, using a little +helper program, mkh, which extracts prototypes given in stylized comments. +More minor cleanup. Buglet fix: it's CHAR_BIT, not CHAR_BITS. Simple +pre-screening of input when a literal string is known to be part of the +RE; this does wonders for performance. + +New in alpha+2: minor bits of cleanup. Notably, the number "32" for the +word width isn't hardwired into regexec.c any more, the public header +file prototypes the functions if __STDC__ is defined, and some small typos +in the manpages have been fixed. + +New in alpha+1: improvements to the manual pages, and an important +extension, the REG_STARTEND option to regexec(). diff --git a/regex/FreeBSD/cname.h b/regex/FreeBSD/cname.h new file mode 100644 index 0000000..26355e8 --- /dev/null +++ b/regex/FreeBSD/cname.h @@ -0,0 +1,140 @@ +/*- + * Copyright (c) 1992, 1993, 1994 Henry Spencer. + * Copyright (c) 1992, 1993, 1994 + * The Regents of the University of California.

+.Sh DESCRIPTION +Regular expressions +.Pq Dq RE Ns s , +as defined in +.St -p1003.2 , +come in two forms: +modern REs (roughly those of +.Xr egrep 1 ; +1003.2 calls these +.Dq extended +REs) +and obsolete REs (roughly those of +.Xr ed 1 ; +1003.2 +.Dq basic +REs). +Obsolete REs mostly exist for backward compatibility in some old programs; +they will be discussed at the end. +.St -p1003.2 +leaves some aspects of RE syntax and semantics open; +`\(dd' marks decisions on these aspects that +may not be fully portable to other +.St -p1003.2 +implementations. +.Pp +A (modern) RE is one\(dd or more non-empty\(dd +.Em branches , +separated by +.Ql \&| . +It matches anything that matches one of the branches. +.Pp +A branch is one\(dd or more +.Em pieces , +concatenated. +It matches a match for the first, followed by a match for the second, etc. +.Pp +A piece is an +.Em atom +possibly followed +by a single\(dd +.Ql \&* , +.Ql \&+ , +.Ql \&? , +or +.Em bound . +An atom followed by +.Ql \&* +matches a sequence of 0 or more matches of the atom. +An atom followed by +.Ql \&+ +matches a sequence of 1 or more matches of the atom. +An atom followed by +.Ql ?\& +matches a sequence of 0 or 1 matches of the atom. +.Pp +A +.Em bound +is +.Ql \&{ +followed by an unsigned decimal integer, +possibly followed by +.Ql \&, +possibly followed by another unsigned decimal integer, +always followed by +.Ql \&} . +The integers must lie between 0 and +.Dv RE_DUP_MAX +(255\(dd) inclusive, +and if there are two of them, the first may not exceed the second. +An atom followed by a bound containing one integer +.Em i +and no comma matches +a sequence of exactly +.Em i +matches of the atom. +An atom followed by a bound +containing one integer +.Em i +and a comma matches +a sequence of +.Em i +or more matches of the atom. +An atom followed by a bound +containing two integers +.Em i +and +.Em j +matches +a sequence of +.Em i +through +.Em j +(inclusive) matches of the atom. +.Pp +An atom is a regular expression enclosed in +.Ql () +(matching a match for the +regular expression), +an empty set of +.Ql () +(matching the null string)\(dd, +a +.Em bracket expression +(see below), +.Ql .\& +(matching any single character), +.Ql \&^ +(matching the null string at the beginning of a line), +.Ql \&$ +(matching the null string at the end of a line), a +.Ql \e +followed by one of the characters +.Ql ^.[$()|*+?{\e +(matching that character taken as an ordinary character), +a +.Ql \e +followed by any other character\(dd +(matching that character taken as an ordinary character, +as if the +.Ql \e +had not been present\(dd), +or a single character with no other significance (matching that character). +A +.Ql \&{ +followed by a character other than a digit is an ordinary +character, not the beginning of a bound\(dd. +It is illegal to end an RE with +.Ql \e . +.Pp +A +.Em bracket expression +is a list of characters enclosed in +.Ql [] . +It normally matches any single character from the list (but see below). +If the list begins with +.Ql \&^ , +it matches any single character +(but see below) +.Em not +from the rest of the list. +If two characters in the list are separated by +.Ql \&- , +this is shorthand +for the full +.Em range +of characters between those two (inclusive) in the +collating sequence, +.No e.g. Ql [0-9] +in ASCII matches any decimal digit. +It is illegal\(dd for two ranges to share an +endpoint, +.No e.g. Ql a-c-e . +Ranges are very collating-sequence-dependent, +and portable programs should avoid relying on them. +.Pp +To include a literal +.Ql \&] +in the list, make it the first character +(following a possible +.Ql \&^ ) . +To include a literal +.Ql \&- , +make it the first or last character, +or the second endpoint of a range. +To use a literal +.Ql \&- +as the first endpoint of a range, +enclose it in +.Ql [.\& +and +.Ql .]\& +to make it a collating element (see below). +With the exception of these and some combinations using +.Ql \&[ +(see next paragraphs), all other special characters, including +.Ql \e , +lose their special significance within a bracket expression. +.Pp +Within a bracket expression, a collating element (a character, +a multi-character sequence that collates as if it were a single character, +or a collating-sequence name for either) +enclosed in +.Ql [.\& +and +.Ql .]\& +stands for the +sequence of characters of that collating element. +The sequence is a single element of the bracket expression's list. +A bracket expression containing a multi-character collating element +can thus match more than one character, +e.g.\& if the collating sequence includes a +.Ql ch +collating element, +then the RE +.Ql [[.ch.]]*c +matches the first five characters +of +.Ql chchcc . +.Pp +Within a bracket expression, a collating element enclosed in +.Ql [= +and +.Ql =] +is an equivalence class, standing for the sequences of characters +of all collating elements equivalent to that one, including itself. +(If there are no other equivalent collating elements, +the treatment is as if the enclosing delimiters were +.Ql [.\& +and +.Ql .] . ) +For example, if +.Ql x +and +.Ql y +are the members of an equivalence class, +then +.Ql [[=x=]] , +.Ql [[=y=]] , +and +.Ql [xy] +are all synonymous. +An equivalence class may not\(dd be an endpoint +of a range. +.Pp +Within a bracket expression, the name of a +.Em character class +enclosed in +.Ql [: +and +.Ql :] +stands for the list of all characters belonging to that +class. +Standard character class names are: +.Pp +.Bl -column "alnum" "digit" "xdigit" -offset indent +.It Em "alnum digit punct" +.It Em "alpha graph space" +.It Em "blank lower upper" +.It Em "cntrl print xdigit" +.El +.Pp +These stand for the character classes defined in +.Xr ctype 3 . +A locale may provide others. +A character class may not be used as an endpoint of a range. +.Pp +A bracketed expression like +.Ql [[:class:]] +can be used to match a single character that belongs to a character +class. +The reverse, matching any character that does not belong to a specific +class, the negation operator of bracket expressions may be used: +.Ql [^[:class:]] . +.Pp +There are two special cases\(dd of bracket expressions: +the bracket expressions +.Ql [[:<:]] +and +.Ql [[:>:]] +match the null string at the beginning and end of a word respectively. +A word is defined as a sequence of word characters +which is neither preceded nor followed by +word characters. +A word character is an +.Em alnum +character (as defined by +.Xr ctype 3 ) +or an underscore. +This is an extension, +compatible with but not specified by +.St -p1003.2 , +and should be used with +caution in software intended to be portable to other systems. +.Pp +In the event that an RE could match more than one substring of a given +string, +the RE matches the one starting earliest in the string. +If the RE could match more than one substring starting at that point, +it matches the longest. +Subexpressions also match the longest possible substrings, subject to +the constraint that the whole match be as long as possible, +with subexpressions starting earlier in the RE taking priority over +ones starting later. +Note that higher-level subexpressions thus take priority over +their lower-level component subexpressions. +.Pp +Match lengths are measured in characters, not collating elements. +A null string is considered longer than no match at all. +For example, +.Ql bb* +matches the three middle characters of +.Ql abbbc , +.Ql (wee|week)(knights|nights) +matches all ten characters of +.Ql weeknights , +when +.Ql (.*).*\& +is matched against +.Ql abc +the parenthesized subexpression +matches all three characters, and +when +.Ql (a*)* +is matched against +.Ql bc +both the whole RE and the parenthesized +subexpression match the null string. +.Pp +If case-independent matching is specified, +the effect is much as if all case distinctions had vanished from the +alphabet. +When an alphabetic that exists in multiple cases appears as an +ordinary character outside a bracket expression, it is effectively +transformed into a bracket expression containing both cases, +.No e.g. Ql x +becomes +.Ql [xX] . +When it appears inside a bracket expression, all case counterparts +of it are added to the bracket expression, so that (e.g.) +.Ql [x] +becomes +.Ql [xX] +and +.Ql [^x] +becomes +.Ql [^xX] . +.Pp +No particular limit is imposed on the length of REs\(dd. +Programs intended to be portable should not employ REs longer +than 256 bytes, +as an implementation can refuse to accept such REs and remain +POSIX-compliant. +.Pp +Obsolete +.Pq Dq basic +regular expressions differ in several respects. +.Ql \&| +is an ordinary character and there is no equivalent +for its functionality. +.Ql \&+ +and +.Ql ?\& +are ordinary characters, and their functionality +can be expressed using bounds +.No ( Ql {1,} +or +.Ql {0,1} +respectively). +Also note that +.Ql x+ +in modern REs is equivalent to +.Ql xx* . +The delimiters for bounds are +.Ql \e{ +and +.Ql \e} , +with +.Ql \&{ +and +.Ql \&} +by themselves ordinary characters. +The parentheses for nested subexpressions are +.Ql \e( +and +.Ql \e) , +with +.Ql \&( +and +.Ql \&) +by themselves ordinary characters. +.Ql \&^ +is an ordinary character except at the beginning of the +RE or\(dd the beginning of a parenthesized subexpression, +.Ql \&$ +is an ordinary character except at the end of the +RE or\(dd the end of a parenthesized subexpression, +and +.Ql \&* +is an ordinary character if it appears at the beginning of the +RE or the beginning of a parenthesized subexpression +(after a possible leading +.Ql \&^ ) . +Finally, there is one new type of atom, a +.Em back reference : +.Ql \e +followed by a non-zero decimal digit +.Em d +matches the same sequence of characters +matched by the +.Em d Ns th +parenthesized subexpression +(numbering subexpressions by the positions of their opening parentheses, +left to right), +so that (e.g.) +.Ql \e([bc]\e)\e1 +matches +.Ql bb +or +.Ql cc +but not +.Ql bc . +.Sh ENHANCED FEATURES +When the +.Dv REG_ENHANCED +flag is passed to one of the +.Fn regcomp +variants, additional features are activated. +Like the enhanced +.Nm regex +implementations in scripting languages such as +.Xr perl 1 +and +.Xr python 1 , +these additional features may conflict with the +.St -p1003.2 +standards in some ways. +Use this with care in situations which require portability +(including to past versions of the Mac OS X using the previous +.Nm regex +implementation). +.Pp +For enhanced basic REs, +.Ql \&+ , +.Ql \&? +and +.Ql \&| +remain regular characters, but +.Ql \e+ , +.Ql \e? +and +.Ql \e| +have the same special meaning as the unescaped characters do for +extended REs, i.e., one or more matches, zero or one matches and alteration, +respectively. +For enhanced extended REs, +back references are available. +Additional enhanced features are listed below. +.Pp +Within a bracket expression, most characters lose their magic. +This also applies to the additional enhanced features, which don't operate +inside a bracket expression. +.Ss Assertions (available for both enhanced basic and enhanced extended REs) +In addition to +.Ql \&^ +and +.Ql \&$ +(the assertions that match the null string at the beginning and end of line, +respectively), the following assertions become available: +.Bl -tag -width ".Sy \eB" -offset indent +.It Sy \e< +Matches the null string at the beginning of a word. +This is equivalent to +.Ql [[:<:]] . +.It Sy \e> +Matches the null string at the end of a word. +This is equivalent to +.Ql [[:>:]] . +.It Sy \eb +Matches the null string at a word boundary (either the beginning or end of +a word). +.It Sy \eB +Matches the null string where there is no word boundary. +This is the opposite of +.Ql \eb . +.El +.Ss Shortcuts (available for both enhanced basic and enhanced extended REs) +The following shortcuts can be used to replace more complicated +bracket expressions. +.Bl -tag -width ".Sy \eD" -offset indent +.It Sy \ed +Matches a digit character. +This is equivalent to +.Ql [[:digit:]] . +.It Sy \eD +Matches a non-digit character. +This is equivalent to +.Ql [^[:digit:]] . +.It Sy \es +Matches a space character. +This is equivalent to +.Ql [[:space:]] . +.It Sy \eS +Matches a non-space character. +This is equivalent to +.Ql [^[:space:]] . +.It Sy \ew +Matches a word character. +This is equivalent to +.Ql [[:alnum:]_] . +.It Sy \eW +Matches a non-word character. +This is equivalent to +.Ql [^[:alnum:]_] . +.El +.Ss Literal Sequences (available for both enhanced basic and enhanced extended REs) +.Pp +Literals are normally just ordinary characters that are matched directly. +Under enhanced mode, certain character sequences are +converted to specific literals. +.Bl -tag -width ".Sy \ea" -offset indent +.It Sy \ea +The +.Dq bell +character (ASCII code 7). +.It Sy \ee +The +.Dq escape +character (ASCII code 27). +.It Sy \ef +The +.Dq form-feed +character (ASCII code 12). +.It Sy \en +The +.Dq new-line/line-feed +character (ASCII code 10). +.It Sy \er +The +.Dq carriage-return +character (ASCII code 13). +.It Sy \et +The +.Dq horizontal-tab +character (ASCII code 9). +.El +.Pp +Literals can also be specified directly, using their wide character values. +Note that when matching a multibyte character string, the string's bytes +are converted to wide character before comparing. +This means that a single literal wide character value may match more than +one string byte, depending on the locale's wide character encoding. +.Bl -tag -width ".Sy \ex{ Ns Em x.. Ns Sy \&}" -offset indent +.It Sy \ex Ns Em x.. +An arbitray eight-bit value. +The +.Em x.. +sequence represents zero, one or two hexadecimal digits. +(Note: if +.Em x.. +is less than two hexadecimal digits, and the character following this sequence +happens to be a hexadecimal digit, use the (following) brace form to avoid +confusion.) +.It Sy \ex{ Ns Em x.. Ns Sy \&} +An arbitrary, up to 32-bit value. +The +.Em x.. +sequence is an arbitrary sequence of hexadecimal digits that is long enough +to represent the necessary value. +.El +.Ss Inline Literal Mode (available for both enhanced basic and enhanced extended REs) +A +.Ql \eQ +sequence causes literal +.Pq Dq quote +mode to be entered, +while +.Ql \eE +ends literal mode, and returns to normal regular expression processing. +This is similar to specifying the +.Dv REG_NOSPEC +(or +.Dv REG_LITERAL ) +option to +.Fn regcomp , +except that rather than applying to the whole RE string, it only applies to +the part between the +.Ql \eQ +and +.Ql \eE . +Note that it is not possible to have a +.Ql \eE +in the middle of an inline literal range, as that would terminate literal mode +prematurely. +.Ss Minimal Repetitions (available for enhanced extended REs only) +By default, the repetition operators, +.Ql \&* , +.Em bound , +.Ql \&? +and +.Ql \&+ +are +.Em greedy ; +they try to match as many times as possible. +In enhanced mode, appending a +.Ql \&? +to a repetition operator makes it minimal (or +.Em ungreedy ) ; +it tries to match the fewest number of times (including zero times, as +appropriate). +.Pp +For example, against the string +.Ql aaa , +the RE +.Ql a* +would match the entire string, +while +.Ql a*? +would match the null string at the beginning of the line +(matches zero times). +Likewise, against the string +.Ql ababab , +the RE +.Ql .*b , +would also match the entire string, +while +.Ql .*?b +would only match the first two characters. +.Pp +The +.Fn regcomp +flag +.Dv REG_UNGREEDY +will make the regular +.Pq greedy +repetition operators ungreedy by default. +Appending +.Ql \&? +makes them greedy again. +.Pp +Note that minimal repetitions are not specified by an official +standard, so there may be differences between different implementations. +In the current implementation, minimal repetitions have a high precedence, +and can cause other standards requirements to be violated. +For instance, on the string +.Ql aaaaa , +the RE +.Ql (aaa??)* +will only match the first four characters, violating the rules that the longest +possible match is made and the longest subexpressions are matched. +Using +.Ql (aaa??)*$ +forces the entire string to be matched. +.Ss Non-capturing Parenthesized Subexpressions (available for enhanced extended REs only) +Normally, the match offsets to parenthesized subexpressions are +recorded in the +.Fa pmatch +array (that is, when +.Dv REG_NOSUB +is not specified, and +.Fa nmatch +is large enough to encompass the parenthesized subexpression in question). +In enhanced mode, if the first two characters following the left parenthesis +are +.Ql ?: , +grouping of the remaining contents is done, but the corresponding offsets are +not recorded in the +.Fa pmatch +array. +For example, against the string +.Ql fubar , +the RE +.Ql (fu)(bar) +would have two subexpression matches in +.Fa pmatch ; +the first for +.Ql fu +and the second for +.Ql bar . +But with the RE +.Ql (?:fu)(bar) , +there would only be one subexpression match, that of +.Ql bar . +Furthermore, +against the string +.Ql fufubar , +the RE +.Ql (?fu)*(bar) +would again match the entire string, but only +.Ql bar +would be recorded in +.Fa pmatch . +.Ss Inline Options (available for enhanced extended REs only) +Like the inline literal mode mentioned above, other options can be switched +on and off for part of a RE. +.Ql (? Ns Em o.. Ns \&) +will turn on the options specified in +.Em o.. +(one or more options characters; see below), while +.Ql (?- Ns Em o.. Ns \&) +will turn off the specified options, and +.Ql (? Ns Em o1.. Ns \&- Ns Em o2.. Ns \&) +will turn on the first set of options, and turn off the second set. +.Pp +The available options are: +.Bl -tag -width ".Sy \&U" -offset indent +.It Sy \&i +Turning on this option will ignore case during matching, while turning off +will restore case-sensitive matching. +If +.Dv REG_ICASE +was specified to +.Fn regcomp , +this option can be use to turn that off. +.It Sy \&n +Turn on or off special handling of the newline character. +If +.Dv REG_NEWLINE +was specified to +.Fn regcomp , +this option can be use to turn that off. +.It Sy \&U +Turning on this option will make ungreedy repetitions the default, while +turning off will make greedy repetitions the default. +If +.Dv REG_UNGREEDY +was specified to +.Fn regcomp , +this option can be use to turn that off. +.El +.Pp +The scope of the option change begins immediately following the right +parenthesis, +but up to the end of the enclosing subexpression (if any). +Thus, for example, given the RE +.Ql (fu(?i)bar)baz , +the +.Ql fu +portion matches case sensitively, +.Ql bar +matches case insensitively, and +.Ql baz +matches case sensitively again (since is it outside the scope of the +subexpression in which the inline option was specified). +.Pp +The inline options syntax can be combined with the non-capturing parenthesized +subexpression to limit the option scope to just that of the subexpression. +Then, for example, +.Ql fu(?i:bar)baz +is similar to the previous example, except for the parenthesize subexpression +around +.Ql fu(?i)bar +in the previous example. +.Ss Inline Comments (available for enhanced extended REs only) +The syntax +.Ql (?# Ns Em comment Ns \&) +can be used to embed comments within a RE. +Note that +.Em comment +can not contain a right parenthesis. +Also note that while syntactically, option characters can be added before +the +.Ql \&# +character, they will be ignored. +.Sh SEE ALSO +.Xr regex 3 +.Rs +.%T Regular Expression Notation +.%R IEEE Std +.%N 1003.2 +.%P section 2.8 +.Re +.Sh BUGS +Having two kinds of REs is a botch. +.Pp +The current +.St -p1003.2 +spec says that +.Ql \&) +is an ordinary character in +the absence of an unmatched +.Ql \&( ; +this was an unintentional result of a wording error, +and change is likely. +Avoid relying on it. +.Pp +Back references are a dreadful botch, +posing major problems for efficient implementations. +They are also somewhat vaguely defined +(does +.Ql a\e(\e(b\e)*\e2\e)*d +match +.Ql abbbd ? ) . +Avoid using them. +.Pp +.St -p1003.2 +specification of case-independent matching is vague. +The +.Dq one case implies all cases +definition given above +is current consensus among implementors as to the right interpretation. +.Pp +The bracket syntax for word boundaries is incredibly ugly. diff --git a/regex/FreeBSD/regerror.c b/regex/FreeBSD/regerror.c new file mode 100644 index 0000000..a22066c --- /dev/null +++ b/regex/FreeBSD/regerror.c @@ -0,0 +1,174 @@ +/*- + * Copyright (c) 1992, 1993, 1994 Henry Spencer. + * Copyright (c) 1992, 1993, 1994 + * The Regents of the University of California.

+in this case, the result in +.Fa errbuf +is the decimal digits of +the numeric value of the error code +(0 if the name is not recognized). +.Dv REG_ITOA +and +.Dv REG_ATOI +are intended primarily as debugging facilities; +they are extensions, +compatible with but not specified by +.St -p1003.2 , +and should be used with +caution in software intended to be portable to other systems. +Be warned also that they are considered experimental and changes are possible. +.Pp +The +.Fn regfree +function +frees any dynamically-allocated storage associated with the compiled RE +pointed to by +.Fa preg . +The remaining +.Ft regex_t +is no longer a valid compiled RE +and the effect of supplying it to +.Fn regexec +or +.Fn regerror +is undefined. +.Pp +None of these functions references global variables except for tables +of constants; +all are safe for use from multiple threads if the arguments are safe. +.Sh EXTENDED APIS +These extended APIs are available in Mac OS X 10.8 and beyond, when the +deployment target is 10.8 or later. +It should also be noted that any of the +.Fn regcomp +variants may be used to initialize a +.Ft regex_t +structure, that can then be passed to any of the +.Fn regexec +variants. +So it is quite legal to compile a wide character RE and use it to match a +multibyte character string, or vice versa. +.Pp +The +.Fn regncomp +routine compiles regular expressions like +.Fn regcomp , +but the length of the regular expression string is specified, allowing a string +that is not NUL terminated and/or contains NUL characters. +This is a modern replacement for using +.Fn regcomp +with the +.Dv REG_PEND +option. +.Pp +Similarly, the +.Fn regnexec +routine is like +.Fn regexec , +but the length of the string to match is specified, allowing a string +that is not NUL terminated and/or contains NUL characters. +.Pp +The +.Fn regwcomp +and +.Fn regwexec +variants take a wide-character +.Vt ( wchar_t ) +string for the regular expression and string to match. +And +.Fn regwncomp +and +.Fn regwnexec +are variants that allow specifying the wide character string length, and +so allows wide character strings that are not NUL terminated and/or +contains NUL characters. +.Sh INTERACTION WITH THE LOCALE +When +.Fn regcomp +or one of its variants is run, the regular expression is compiled into an +internal form, which may include specific information about the locale currently +in effect, such as equivalence classes or multi-character collation symbols. +So a reference to the current locale is also stored with the internal form, +so that when +.Fn regexec +is run, it can use the same locale (even if the locale is changed in-between +the calls to +.Fn regcomp +and +.Fn regexec ) . +.Pp +To provide more direct control over which locale is used, +routines with +.Dq Nm _l +appended to their names are provided that work just like the variants +without the +.Dq Nm _l , +except that a locale (via a +.Vt locale_t +variable type) is specified directly. +Note that only variants of +.Fn regcomp +have +.Dq Nm _l +variants, since the +.Fn regexec +variants just use the reference to the locale stored in the internal form. +.Sh IMPLEMENTATION CHOICES +The +.Nm regex +implementation in Mac OS X 10.8 and later is based on a heavily modified subset +of TRE (http://laurikari.net/tre/). +This provides improved performance, better conformance and additional features. +However, both API and binary compatibility have been maintained with previous +releases, so binaries +built on previous releases should work on 10.8 and later, and binaries built on +10.8 and later should be able to run on previous releases (as long as none of +the new variants or new features are used. +.Pp +There are a number of decisions that +.St -p1003.2 +leaves up to the implementor, +either by explicitly saying +.Dq undefined +or by virtue of them being +forbidden by the RE grammar. +This implementation treats them as follows. +.Pp +See +.Xr re_format 7 +for a discussion of the definition of case-independent matching. +.Pp +There is no particular limit on the length of REs, +except insofar as memory is limited. +Memory usage is approximately linear in RE size, and largely insensitive +to RE complexity, except for bounded repetitions. +See +.Sx BUGS +for one short RE using them +that will run almost any system out of memory. +.Pp +A backslashed character other than one specifically given a magic meaning +by +.St -p1003.2 +(such magic meanings occur only in obsolete +.Bq Dq basic +REs) +is taken as an ordinary character. +.Pp +Any unmatched +.Ql [\& +is a +.Dv REG_EBRACK +error. +.Pp +Equivalence classes cannot begin or end bracket-expression ranges. +The endpoint of one range cannot begin another. +.Pp +.Dv RE_DUP_MAX , +the limit on repetition counts in bounded repetitions, is 255. +.Pp +A repetition operator +.Ql ( ?\& , +.Ql *\& , +.Ql +\& , +or bounds) +cannot follow another +repetition operator, except for the use of +.Ql ?\& +for minimal repetition (for enhanced extended REs; see +.Xr re_format 7 +for details). +A repetition operator cannot begin an expression or subexpression +or follow +.Ql ^\& +or +.Ql |\& . +.Pp +.Ql |\& +cannot appear first or last in a (sub)expression or after another +.Ql |\& , +i.e., an operand of +.Ql |\& +cannot be an empty subexpression. +An empty parenthesized subexpression, +.Ql "()" , +is legal and matches an +empty (sub)string. +An empty string is not a legal RE. +.Pp +A +.Ql {\& +followed by a digit is considered the beginning of bounds for a +bounded repetition, which must then follow the syntax for bounds. +A +.Ql {\& +.Em not +followed by a digit is considered an ordinary character. +.Pp +.Ql ^\& +and +.Ql $\& +beginning and ending subexpressions in obsolete +.Pq Dq basic +REs are anchors, not ordinary characters. +.Sh DIAGNOSTICS +Non-zero error codes from +.Fn regcomp +and +.Fn regexec +include the following: +.Pp +.Bl -tag -width REG_ECOLLATE -compact +.It Dv REG_NOMATCH +The +.Fn regexec +function +failed to match +.It Dv REG_BADPAT +invalid regular expression +.It Dv REG_ECOLLATE +invalid collating element +.It Dv REG_ECTYPE +invalid character class +.It Dv REG_EESCAPE +.Ql \e +applied to unescapable character +.It Dv REG_ESUBREG +invalid backreference number +.It Dv REG_EBRACK +brackets +.Ql "[ ]" +not balanced +.It Dv REG_EPAREN +parentheses +.Ql "( )" +not balanced +.It Dv REG_EBRACE +braces +.Ql "{ }" +not balanced +.It Dv REG_BADBR +invalid repetition count(s) in +.Ql "{ }" +.It Dv REG_ERANGE +invalid character range in +.Ql "[ ]" +.It Dv REG_ESPACE +ran out of memory +.It Dv REG_BADRPT +.Ql ?\& , +.Ql *\& , +or +.Ql +\& +operand invalid +.It Dv REG_EMPTY +empty (sub)expression +.It Dv REG_ASSERT +cannot happen - you found a bug +.It Dv REG_INVARG +invalid argument, e.g.\& negative-length string +.It Dv REG_ILLSEQ +illegal byte sequence (bad multibyte character) +.El +.Sh SEE ALSO +.Xr grep 1 , +.Xr re_format 7 +.Pp +.St -p1003.2 , +sections 2.8 (Regular Expression Notation) +and +B.5 (C Binding for Regular Expression Matching). +.Sh HISTORY +The +.Nm regex +implementation is based on a heavily modified subset of TRE +(http://laurikari.net/tre/), originally written by Ville Laurikari. +Previous releases used an implementation originally written by +.An Henry Spencer , +and altered for inclusion in the +.Bx 4.4 +distribution. +.Sh BUGS +The beginning-of-line and end-of-line anchors ( +.Dq ^\& +and +.Dq $\& ) +are currently implemented so that repetitions can not be applied to them. +The standards are unclear about whether this is legal, but other +.Nm regex +packages do support this case. +It is best to avoid this non-portable (and not really very useful) case. +.Pp +The back-reference code is subtle and doubts linger about its correctness +in complex cases. +.Pp +The +.Fn regexec +variants use one of two internal matching engines. +The normal one is linear worst-case time in the length of the text being +searched, and quadratic worst-case time in the length of the used regular +expression. +When back-references are used, a slower, backtracking engine is used. +While all backtracking matching engines suffer from extreme slowness for certain +pathological cases, the normal engines doesn't suffer from these cases. +It is advised to avoid back-references whenever possible. +.Pp +The +.Fn regcomp +variants +implements bounded repetitions by macro expansion, +which is costly in time and space if counts are large +or bounded repetitions are nested. +An RE like, say, +.Ql "((((a{1,100}){1,100}){1,100}){1,100}){1,100}" +will (eventually) run almost any existing machine out of swap space. +.Pp +Due to a mistake in +.St -p1003.2 , +things like +.Ql "a)b" +are legal REs because +.Ql )\& +is +a special character only in the presence of a previous unmatched +.Ql (\& . +This cannot be fixed until the spec is fixed. +.Pp +The standard's definition of back references is vague. +For example, does +.Ql "a\e(\e(b\e)*\e2\e)*d" +match +.Ql "abbbd" ? +Until the standard is clarified, +behavior in such cases should not be relied on. diff --git a/regex/FreeBSD/utils.h b/regex/FreeBSD/utils.h new file mode 100644 index 0000000..2a2ed96 --- /dev/null +++ b/regex/FreeBSD/utils.h @@ -0,0 +1,54 @@ +/*- + * Copyright (c) 1992, 1993, 1994 Henry Spencer. + * Copyright (c) 1992, 1993, 1994 + * The Regents of the University of California.

+function +takes the given file name template and overwrites a portion of it +to create a file name. +This file name is guaranteed not to exist at the time of function invocation +and is suitable for use +by the application. +The template may be any file name with some number of +.Ql X Ns s +appended +to it, for example +.Pa /tmp/temp.XXXXXX . +The trailing +.Ql X Ns s +are replaced with a +unique alphanumeric combination. +The number of unique file names +.Fn mktemp +can return depends on the number of +.Ql X Ns s +provided; six +.Ql X Ns s +will +result in +.Fn mktemp +selecting one of 56800235584 (62 ** 6) possible temporary file names. +.Pp +The +.Fn mkstemp +function +makes the same replacement to the template and creates the template file, +mode 0600, returning a file descriptor opened for reading and writing. +This avoids the race between testing for a file's existence and opening it +for use. +.Pp +The +.Fn mkdtemp +function makes the same replacement to the template as in +.Fn mktemp +and creates the template directory, mode 0700. +.Pp +The +.Fn mkostemp +function +is like +.Fn mkstemp +but allows specifying additional +.Xr open 2 +flags (defined in +.In fcntl.h ) . +The permitted flags are +.Dv O_APPEND , +.Dv O_SHLOCK , +.Dv O_EXLOCK +and +.Dv O_CLOEXEC . +.Pp +The +.Fn mkstemps +and +.Fn mkostemps +functions act the same as +.Fn mkstemp +and +.Fn mkostemp +respectively, +except they permit a suffix to exist in the template. +The template should be of the form +.Pa /tmp/tmpXXXXXXsuffix . +The +.Fn mkstemps +and +.Fn mkostemps +functions +are told the length of the suffix string. +.Pp +The +.Fn mkdtempat_np , +.Fn mkstempsat_np , +and +.Fn mkostempsat_np +functions +act the same as +.Fn mkdtemp , +.Fn mkstemps , +and +.Fn mkostemps +respectively, +except in the case where the +.Ar path +specifies a relative path. +In this case, path is treated as relative to the directory associated with the file descriptor +.Ar fd +instead of the current working directory. +.Sh RETURN VALUES +The +.Fn mktemp +and +.Fn mkdtemp +functions return a pointer to the template on success and +.Dv NULL +on failure. +The +.Fn mkstemp , +.Fn mkostemp , +.Fn mkstemps +and +.Fn mkostemps +functions +return \-1 if no suitable file could be created. +If either call fails an error code is placed in the global variable +.Va errno . +.Sh ERRORS +The +.Fn mkstemp , +.Fn mkostemp , +.Fn mkstemps , +.Fn mkostemps , +and +.Fn mkdtemp +functions +may set +.Va errno +to one of the following values: +.Bl -tag -width Er +.It Bq Er ENOTDIR +The pathname portion of the template is not an existing directory. +.El +.Pp +The +.Fn mkostemp +and +.Fn mkostemps +functions +may also set +.Va errno +to the following value: +.Bl -tag -width Er +.It Bq Er EINVAL +The +.Fa oflags +argument is invalid. +.El +.Pp +The +.Fn mkstemp , +.Fn mkostemp , +.Fn mkstemps , +.Fn mkostemps +and +.Fn mkdtemp +functions +may also set +.Va errno +to any value specified by the +.Xr stat 2 +function. +.Pp +The +.Fn mkstemp , +.Fn mkostemp , +.Fn mkstemps +and +.Fn mkostemps +functions +may also set +.Va errno +to any value specified by the +.Xr open 2 +function. +.Pp +The +.Fn mkdtemp +function +may also set +.Va errno +to any value specified by the +.Xr mkdir 2 +function. +.Sh NOTES +A common problem that results in a core dump is that the programmer +passes in a read-only string to +.Fn mktemp , +.Fn mkstemp , +.Fn mkstemps +or +.Fn mkdtemp . +This is common with programs that were developed before +.St -isoC +compilers were common. +For example, calling +.Fn mkstemp +with an argument of +.Qq /tmp/tempfile.XXXXXX +will result in a core dump due to +.Fn mkstemp +attempting to modify the string constant that was given. +.Sh LEGACY SYNOPSIS +.Fd #include +.Pp +The include file +.In unistd.h +is necessary and sufficient for all functions. +.Sh SEE ALSO +.Xr chmod 2 , +.Xr getpid 2 , +.Xr mkdir 2 , +.Xr open 2 , +.Xr stat 2 , +.Xr compat 5 +.Sh STANDARDS +The +.Fn mkstemp +and +.Fn mkdtemp +functions are expected to conform to +.St -p1003.1-2008 . +The +.Fn mktemp +function is expected to conform to +.St -p1003.1-2001 +and is not specified by +.St -p1003.1-2008 . +The +.Fn mkostemp , +.Fn mkstemps +and +.Fn mkostemps +functions do not conform to any standard. +.Sh HISTORY +A +.Fn mktemp +function appeared in +.At v7 . +The +.Fn mkstemp +function appeared in +.Bx 4.4 . +The +.Fn mkdtemp +function first appeared in +.Ox 2.2 , +and later in +.Fx 3.2 . +The +.Fn mkstemps +function first appeared in +.Ox 2.4 , +and later in +.Fx 3.4 . +The +.Fn mkostemp +and +.Fn mkostemps +functions appeared in OS X 10.12. +.Sh BUGS +This family of functions produces filenames which can be guessed, +though the risk is minimized when large numbers of +.Ql X Ns s +are used to +increase the number of possible temporary filenames. +This makes the race in +.Fn mktemp , +between testing for a file's existence (in the +.Fn mktemp +function call) +and opening it for use +(later in the user application) +particularly dangerous from a security perspective. +Whenever it is possible, +.Fn mkstemp +or +.Fn mkostemp +should be used instead, since it does not have the race condition. +If +.Fn mkstemp +cannot be used, the filename created by +.Fn mktemp +should be created using the +.Dv O_EXCL +flag to +.Xr open 2 +and the return status of the call should be tested for failure. +This will ensure that the program does not continue blindly +in the event that an attacker has already created the file +with the intention of manipulating or reading its contents. diff --git a/stdio/FreeBSD/mktemp.c b/stdio/FreeBSD/mktemp.c new file mode 100644 index 0000000..001cf3e --- /dev/null +++ b/stdio/FreeBSD/mktemp.c @@ -0,0 +1,335 @@ +/* + * Copyright

+if the return value is greater than or equal to the +.Fa size +argument, the string was too short +and some of the printed characters were discarded. +The output is always null-terminated, unless +.Fa size +is 0. +.Pp +The +.Fn sprintf +and +.Fn vsprintf +functions +effectively assume a +.Fa size +of +.Dv INT_MAX + 1. +.Pp +For those routines that write to a user-provided character string, +that string and the format strings should not overlap, as the +behavior is undefined. +.Pp +The format string is composed of zero or more directives: +ordinary +.\" multibyte +characters (not +.Cm % ) , +which are copied unchanged to the output stream; +and conversion specifications, each of which results +in fetching zero or more subsequent arguments. +Each conversion specification is introduced by +the +.Cm % +character. +The arguments must correspond properly (after type promotion) +with the conversion specifier. +After the +.Cm % , +the following appear in sequence: +.Bl -bullet +.It +An optional field, consisting of a decimal digit string followed by a +.Cm $ , +specifying the next argument to access. +If this field is not provided, the argument following the last +argument accessed will be used. +Arguments are numbered starting at +.Cm 1 . +If unaccessed arguments in the format string are interspersed with ones that +are accessed the results will be indeterminate. +.It +Zero or more of the following flags: +.Bl -tag -width ".So \ Sc (space)" +.It Sq Cm # +The value should be converted to an +.Dq alternate form . +For +.Cm c , d , i , n , p , s , +and +.Cm u +conversions, this option has no effect. +For +.Cm o +conversions, the precision of the number is increased to force the first +character of the output string to a zero. +For +.Cm x +and +.Cm X +conversions, a non-zero result has the string +.Ql 0x +(or +.Ql 0X +for +.Cm X +conversions) prepended to it. +For +.Cm a , A , e , E , f , F , g , +and +.Cm G +conversions, the result will always contain a decimal point, even if no +digits follow it (normally, a decimal point appears in the results of +those conversions only if a digit follows). +For +.Cm g +and +.Cm G +conversions, trailing zeros are not removed from the result as they +would otherwise be. +.It So Cm 0 Sc (zero) +Zero padding. +For all conversions except +.Cm n , +the converted value is padded on the left with zeros rather than blanks. +If a precision is given with a numeric conversion +.Cm ( d , i , o , u , i , x , +and +.Cm X ) , +the +.Cm 0 +flag is ignored. +.It Sq Cm \- +A negative field width flag;

Do not use sprintf! + */ + sprintf(onstack, "%s, %s", arbitrary_string, and_another); +#else + /* + * The following two lines demonstrate better use of + * snprintf(). + */ + snprintf(onstack, sizeof(onstack), "%s, %s", arbitrary_string, + and_another); +#endif +} +.Ed +.Pp +The +.Fn printf +and +.Fn sprintf +family of functions are also easily misused in a manner +allowing malicious users to arbitrarily change a running program's +functionality by either causing the program +to print potentially sensitive data +.Dq "left on the stack" , +or causing it to generate a memory fault or bus error +by dereferencing an invalid pointer. +.Pp +.Cm %n +can be used to write arbitrary data to potentially carefully-selected +addresses. +Programmers are therefore strongly advised to never pass untrusted strings +as the +.Fa format +argument, as an attacker can put format specifiers in the string +to mangle your stack, +leading to a possible security hole. +This holds true even if the string was built using a function like +.Fn snprintf , +as the resulting string may still contain user-supplied conversion specifiers +for later interpolation by +.Fn printf . +For this reason, a +.Fa format +argument containing +.Cm %n +is assumed to be untrustworthy if located in writable memory (i.e. memory with +protection PROT_WRITE; see +.Xr mprotect 2 ) +and any attempt to use such an argument is fatal. +Practically, this means that +.Cm %n +is permitted in literal +.Fa format +strings but disallowed in +.Fa format +strings located in normal stack- or heap-allocated memory. +.Pp +Always use the proper secure idiom: +.Pp +.Dl "snprintf(buffer, sizeof(buffer), \*q%s\*q, string);" diff --git a/stdio/FreeBSD/printf.c b/stdio/FreeBSD/printf.c new file mode 100644 index 0000000..e65851a --- /dev/null +++ b/stdio/FreeBSD/printf.c @@ -0,0 +1,67 @@ +/*- + * Copyright (c) 1990, 1993 + * The Regents of the University of California.

+ +int main() { + var = stdout; +} +.Ed +.Sh DESCRIPTION +The standard +.Tn I/O +library provides a simple and efficient buffered stream +.Tn I/O +interface. +Input and output is mapped into logical data streams +and the physical +.Tn I/O +characteristics are concealed. +The functions and macros are listed +below; more information is available from the individual man pages. +.Pp +A stream is associated with an external file (which may be a physical +device) by +.Em opening +a file, which may involve creating a new file. +Creating an +existing file causes its former contents to be discarded. +If a file can support positioning requests (such as a disk file, as opposed +to a terminal) then a +.Em file position indicator +associated with the stream is positioned at the start of the file (byte +zero), unless the file is opened with append mode. +If append mode +is used, the position indicator will be placed at the end-of-file. +The position indicator is maintained by subsequent reads, writes +and positioning requests. +All input occurs as if the characters +were read by successive calls to the +.Xr fgetc 3 +function; all output takes place as if all characters were +written by successive calls to the +.Xr fputc 3 +function. +.Pp +A file is disassociated from a stream by +.Em closing +the file. +Output streams are flushed (any unwritten buffer contents are transferred +to the host environment) before the stream is disassociated from the file. +The value of a pointer to a +.Dv FILE +object is indeterminate (garbage) after a file is closed. +.Pp +A file may be subsequently reopened, by the same or another program +execution, and its contents reclaimed or modified (if it can be repositioned +at the start). +If the main function returns to its original caller, or +the +.Xr exit 3 +function is called, all open files are closed (hence all output +streams are flushed) before program termination. +Other methods +of program termination may not close files properly and hence +buffered output may be lost. +In particular, +.Xr _exit 2 +does not flush stdio files. +Neither does an exit due to a signal. +Buffers are flushed by +.Xr abort 3 +as required by POSIX, although previous implementations did not. +.Pp +This implementation makes no distinction between +.Dq text +and +.Dq binary +streams. +In effect, all streams are binary. +No translation is performed and no extra padding appears on any stream. +.Pp +At program startup, three streams are predefined and need not be +opened explicitly: +.Bl -bullet -compact -offset indent +.It +.Em standard input +(for reading conventional input), +.It +.Em standard output +(for writing conventional output), and +.It +.Em standard error +(for writing diagnostic output). +.El +These streams are abbreviated +.Dv stdin , stdout +and +.Dv stderr . +Initially, the standard error stream +is unbuffered; the standard input and output streams are +fully buffered if and only if the streams do not refer to +an interactive or +.Dq terminal +device, as determined by the +.Xr isatty 3 +function. +In fact, +.Em all +freshly-opened streams that refer to terminal devices +default to line buffering, and +pending output to such streams is written automatically +whenever such an input stream is read. +Note that this applies only to +.Dq "true reads" ; +if the read request can be satisfied by existing buffered data, +no automatic flush will occur. +In these cases, +or when a large amount of computation is done after printing +part of a line on an output terminal, it is necessary to +.Xr fflush 3 +the standard output before going off and computing so that the output +will appear. +Alternatively, these defaults may be modified via the +.Xr setvbuf 3 +function. +.Pp +The +.Nm +library is a part of the library +.Nm libc +and routines are automatically loaded as needed by the C compiler. +The +.Tn SYNOPSIS +sections of the following manual pages indicate which include files +are to be used, what the compiler declaration for the function +looks like and which external variables are of interest. +.Pp +The following are defined as macros; +these names may not be re-used +without first removing their current definitions with +.Ic #undef : +.Dv BUFSIZ , +.Dv EOF , +.Dv FILENAME_MAX , +.Dv FOPEN_MAX , +.Dv L_ctermid , +.Dv L_cuserid , +.Dv L_tmpnam , +.Dv NULL , +.Dv P_tmpdir , +.Dv SEEK_CUR , +.Dv SEEK_END , +.Dv SEEK_SET , +.Dv TMP_MAX , +.Dv clearerr , +.Dv clearerr_unlocked , +.Dv feof , +.Dv feof_unlocked , +.Dv ferror , +.Dv ferror_unlocked , +.Dv fileno , +.Dv fileno_unlocked , +.Dv fropen , +.Dv fwopen , +.Dv getc , +.Dv getc_unlocked , +.Dv getchar , +.Dv getchar_unlocked , +.Dv putc , +.Dv putc_unlocked , +.Dv putchar , +.Dv putchar_unlocked , +.Dv stderr , +.Dv stdin +and +.Dv stdout . +Function versions of the macro functions +.Dv clearerr , +.Dv clearerr_unlocked , +.Dv feof , +.Dv feof_unlocked , +.Dv ferror , +.Dv ferror_unlocked , +.Dv fileno , +.Dv fileno_unlocked , +.Dv getc , +.Dv getc_unlocked , +.Dv getchar , +.Dv getchar_unlocked , +.Dv putc , +.Dv putc_unlocked , +.Dv putchar , +and +.Dv putchar_unlocked +exist and will be used if the macro +definitions are explicitly removed. +.Sh LEGACY SYNOPSIS +The -D_NONSTD_SOURCE flag can be used +to allow stdin, stdout, and/or stderr +to be evaluated at compile/link time, as: +.Bd -literal -offset indent +#include + +static FILE *var = stdout;

+otherwise at most this many characters are scanned +in processing the conversion. +Before conversion begins, +most conversions skip white space; +this white space is not counted against the field width. +.Pp +The following conversions are available: +.Bl -tag -width XXXX +.It Cm % +Matches a literal +.Ql % . +That is, +.Dq Li %% +in the format string +matches a single input +.Ql % +character. +No conversion is done, and assignment does not occur. +.It Cm d +Matches an optionally signed decimal integer; +the next pointer must be a pointer to +.Vt int . +.It Cm i +Matches an optionally signed integer; +the next pointer must be a pointer to +.Vt int . +The integer is read in base 16 if it begins +with +.Ql 0x +or +.Ql 0X , +in base 8 if it begins with +.Ql 0 , +and in base 10 otherwise. +Only characters that correspond to the base are used. +.It Cm o +Matches an octal integer; +the next pointer must be a pointer to +.Vt "unsigned int" . +.It Cm u +Matches an optionally signed decimal integer; +the next pointer must be a pointer to +.Vt "unsigned int" . +.It Cm x , X +Matches an optionally signed hexadecimal integer; +the next pointer must be a pointer to +.Vt "unsigned int" . +.It Cm a , A , e , E , f , F , g , G +Matches a floating-point number in the style of +.Xr wcstod 3 . +The next pointer must be a pointer to +.Vt float +(unless +.Cm l +or +.Cm L +is specified.) +.It Cm s +Matches a sequence of non-white-space wide characters; +the next pointer must be a pointer to +.Vt char , +and the array must be large enough to accept the multibyte representation +of all the sequence and the +terminating +.Dv NUL +character. +The input string stops at white space +or at the maximum field width, whichever occurs first. +.Pp +If an +.Cm l +qualifier is present, the next pointer must be a pointer to +.Vt wchar_t , +into which the input will be placed. +.It Cm S +The same as +.Cm ls . +.It Cm c +Matches a sequence of +.Em width +count +wide characters (default 1); +the next pointer must be a pointer to +.Vt char , +and there must be enough room for the multibyte representation +of all the characters +(no terminating +.Dv NUL +is added). +The usual skip of leading white space is suppressed. +To skip white space first, use an explicit space in the format. +.Pp +If an +.Cm l +qualifier is present, the next pointer must be a pointer to +.Vt wchar_t , +into which the input will be placed. +.It Cm C +The same as +.Cm lc . +.It Cm \&[ +Matches a nonempty sequence of characters from the specified set +of accepted characters; +the next pointer must be a pointer to +.Vt char , +and there must be enough room for the multibyte representation of +all the characters in the string, +plus a terminating +.Dv NUL +character. +The usual skip of leading white space is suppressed. +The string is to be made up of characters in +(or not in) +a particular set; +the set is defined by the characters between the open bracket +.Cm [ +character +and a close bracket +.Cm ] +character. +The set +.Em excludes +those characters +if the first character after the open bracket is a circumflex +.Cm ^ . +To include a close bracket in the set, +make it the first character after the open bracket +or the circumflex; +any other position will end the set. +To include a hyphen in the set, +make it the last character before the final close bracket; +some implementations of +.Fn wscanf +use +.Dq Li A-Z +to represent the range of characters between +.Ql A +and +.Ql Z . +The string ends with the appearance of a character not in the +(or, with a circumflex, in) set +or when the field width runs out. +.Pp +If an +.Cm l +qualifier is present, the next pointer must be a pointer to +.Vt wchar_t , +into which the input will be placed. +.It Cm p +Matches a pointer value (as printed by +.Ql %p +in +.Xr wprintf 3 ) ; +the next pointer must be a pointer to +.Vt void . +.It Cm n +Nothing is expected; +instead, the number of characters consumed thus far from the input +is stored through the next pointer, +which must be a pointer to +.Vt int . +This is +.Em not +a conversion, although it can be suppressed with the +.Cm * +flag. +.El +.Pp +The decimal point +character is defined in the program's locale (category +.Dv LC_NUMERIC ) . +.Pp +For backwards compatibility, a +.Dq conversion +of +.Ql %\e0 +causes an immediate return of +.Dv EOF . +.Sh RETURN VALUES +These functions return the number of input items assigned, +which can be fewer than provided for, or even zero, +in the event of a matching failure. +Zero indicates that, while there was input available, +no conversions were assigned; +typically, this is due to an invalid input character, +such as an alphabetic character for a +.Ql %d +conversion. +The value +.Dv EOF +is returned if an input failure occurs before any conversion such as an +end-of-file occurs. +If an error or end-of-file occurs after conversion +has begun, +the number of conversions which were successfully completed is returned. +.Sh SEE ALSO +.Xr fgetwc 3 , +.Xr scanf 3 , +.Xr wcrtomb 3 , +.Xr wcstod 3 , +.Xr wcstol 3 , +.Xr wcstoul 3 , +.Xr wprintf 3 , +.Xr wscanf_l 3 +.Sh STANDARDS +The +.Fn fwscanf , +.Fn wscanf , +.Fn swscanf , +.Fn vfwscanf , +.Fn vwscanf , +and +.Fn vswscanf +functions +conform to +.St -isoC-99 . +.Sh BUGS +In addition to the bugs documented in +.Xr scanf 3 , +.Fn wscanf +does not support the +.Dq Li A-Z +notation for specifying character ranges with the character +class conversion +.Pq Sq Cm %[ . diff --git a/stdio/FreeBSD/wscanf.c b/stdio/FreeBSD/wscanf.c new file mode 100644 index 0000000..99dc48d --- /dev/null +++ b/stdio/FreeBSD/wscanf.c @@ -0,0 +1,61 @@ +/*- + * Copyright (c) 2002 Tim J.

convenient way to convert one or more arguments +to various forms for output, under the control of a format string. +The format string may contain any number of conversion specifications, which +start with the +.Sq Li % +character and end with a conversion specifier character (like +.Sq Li d +or +.Sq Li f ) , +with conversion flag characters in-between. +.Pp +Extensible printf is an enhancement that allows adding new (user-defined) +conversion specifiers, or modifying/removing existing ones. +The implementation of extensible printf in Mac OS X is derived from the +FreeBSD version, which is based on the one in GNU libc (GLIBC). +Documentation for the GLIBC version is available at: +.Pp +.Li http://www.gnu.org/software/libc/manual/html_node/Customizing-Printf.html +.Pp +The main problem with the usual forms of extensible printf is that +changes to +.Xr printf 3 +are program-wide. +But this is unsafe, since frameworks, +libraries or some other thread could change printf behavior in ways +unexpected by the main program, or the latter could unexpectedly affect the +former. +.Pp +So instead, the implementation used in Mac OS X makes +changes to conversion specifiers within printf domains, +which are independent structures containing the specifier definitions. +These domains are created as described in +.Xr xprintf_domain 3 , +and once set up, it can be passed to a +.Xr xprintf 3 +variant along with the format string and arguments to generate output. +The standard +.Xr printf 3 +behavior is never affected. +.Pp +To define a new conversion specifier, two function typedefs are defined, and +the user must provide two functions based on these typedefs. +These functions will get called from extensible printf while processing +the corresponding conversion specification. +.Pp +During the first of three phases of extensible printf processing, the format +string is parsed, and for each conversion specification, a +.Vt struct printf_info +is created, containing the option flags specified in the +conversion specification as well as other settings. +Important fields in +.Vt struct printf_info +are: +.Bl -tag -width ".Va is_long_double" +.It Va alt +Boolean value whether the +.Sq Li # +flag was specified. +.It Va context +A +.Vt void * +pointer to arbitrary data specified in the original call to +.Xr register_printf_domain_function 3 . +.It Va group +Boolean value whether the +.Sq Li ' +flag was specified. +.It Va is_char +Boolean value whether the +.Sq Li hh +flag was specified. +.It Va is_intmax +Boolean value whether the +.Sq Li j +flag was specified. +.It Va is_long +Boolean value whether the +.Sq Li l +flag was specified. +.It Va is_long_double +Boolean value whether the +.Sq Li L +or +.Sq Li ll +flags were specified. +.It Va is_ptrdiff +Boolean value whether the +.Sq Li t +flag was specified. +.It Va is_quad +Boolean value whether the +.Sq Li q +flag was specified. +.It Va is_short +Boolean value whether the +.Sq Li h +flag was specified. +.It Va is_size +Boolean value whether the +.Sq Li z +flag was specified. +.It Va is_vec +Boolean value whether the +.Sq Li v +flag was specified. +.It Va left +Boolean value whether the +.Sq Li - +flag was specified. +.It Va loc +The extended locale (see +.Xr xlocale 3 ) +specified by the extensible printf caller (never +.Dv NULL ) . +.It Va pad +The padding character; either +.Sq Li 0 +or space. +.It Va prec +The value of the optional precision. +-1 means the precision was unspecified. +.It Va showsign +Boolean value whether the +.Sq Li + +flag was specified. +.It Va signchar +The sign character, either +.Sq Li + , +space or zero if none. +.It Va space +Boolean value whether the space flag was specified. +.It Va spec +The specifier character itself. +.It Va vsep +The separator character between vector items (using the +.Sq Li v +flag). +Can be any one of the four characters +.Dq Li ,:;_ +or +.Sq Li X +if no separator character was specified (meaning that a space is used as the +separator, unless the specifier is +.Sq Li c , +in which case no separator is used). +.It Va width +The value of the minimum field width (defaults to zero). +.El +.Pp +All other structure fields are either unused or private (and shouldn't be +used). +.Pp +This +.Vt struct printf_info +structure is then passed to the corresponding +.Nm printf_arginfo_function +callback function. +The callback function should return the number of consecutive arguments the +specifier handles, including zero (the maximum number of consecutive arguments +a single specifier can handle is +.Dv __PRINTFMAXARG , +which is currently set to 2, but could be increased in the future if there is +need). +.Pp +The callback function is also passed an integer array and the length of that +array; the length will typically be +.Dv __PRINTFMAXARG . +The function should fill out the array up to the number of arguments it expects, +using the following values: +.Bl -tag -width ".Dv PA_POINTER" +.It Dv PA_CHAR +The argument type is an +.Vt int +cast to a +.Vt char . +.It Dv PA_DOUBLE +The argument type is a +.Vt double . +OR-ing +.Dv PA_DOUBLE +with +.Dv PA_FLAG_LONG_DOUBLE +specifies a +.Vt "long double" +type. +.It Dv PA_FLOAT +(Defined but unused; best to avoid, since +.Vt float +is automatically promoted to +.Vt double +anyways.) +.It Dv PA_INT +The argument type is +.Vt int +(either signed or unsigned). +The size can be adjusted by OR-ing the following values to +.Dv PA_INT : +.Bl -tag -width ".Dv PA_FLAG_LONG_LONG" +.It Dv PA_FLAG_INTMAX +The integer is the size of a +.Vt intmax_t . +.It Dv PA_FLAG_LONG +The integer is the size of a +.Vt long . +.It Dv PA_FLAG_LONG_LONG +The integer is the size of a +.Vt "long long" . +.It Dv PA_FLAG_PTRDIFF +The integer is the size of a +.Vt ptrdiff_t . +.It Dv PA_FLAG_QUAD +The integer is the size of a +.Vt quad_t +(deprecated). +.It Dv PA_FLAG_SHORT +The integer is the size of a +.Vt short . +.It Dv PA_FLAG_SIZE +The integer is the size of a +.Vt size_t . +.El +.It Dv PA_POINTER +The argument type is a pointer type, cast to a +.Vt "void *" . +.It Dv PA_STRING +The argument type is a null-terminated character string +.Vt ( "char *" ) . +.It Dv PA_VECTOR +The argument type is an AltiVec or SSE vector (16 bytes). +.It Dv PA_WCHAR +The argument type is a +.Vt wchar_t . +.It Dv PA_WSTRING +The argument type is a null-terminated wide character string +.Vt ( "wchar_t *" ) . +.El +.Pp +After the +.Nm printf_arginfo_function +returns, phase 2 of extensible printf processing involves converting the +argument according to the types specified by the returned type array. +Note that positional arguments are dealt with here as well. +.Pp +Then in phase 3, output is generated, either from the text in-between the +conversion specifications, or by calling the so-called rendering functions +associated with each conversion specifier (with typedef +.Nm printf_function ) . +The rendering function is passed the same +.Vt struct printf_info +structure, as well as an array of pointers to each of the arguments converted +in phase 2 that it is responsible for. +The callback should write its output to the provided output +stdio stream, and then return the number of characters written. +.Sh EXAMPLE +Here is an example that demonstrates many of the features of extensible printf: +.Bd -literal +#include +#include +#include +#include

create a conversion specifier that displays a Coordinate type, either just +as two floating point numbers, or with the +.Sq Li # +(alternate form) flag, as parenthesized numbers separated by a comma. +Note the use of +.Nm printf_l +to do the actual output; this is using regular printf from within an extensible +printf renderer callback. +The use of +.Nm printf_l +also insures correct handling of

PERFORMANCE +Because of the three phase processing of extensible printf, as well as the +use of two callbacks for each conversion specifier, performance is +considerably slower than the one pass, highly optimized regular +.Xr printf 3 . +Recursive use of +.Xr printf 3 +from within an extensible printf renderer callback +(as in the +.Sx EXAMPLE +above) adds additional overhead. +.Pp +To ameliorate some of this slowness, the concept of separate compilation +and execution phases has be added to extensible printf. +The functions in +.Xr xprintf_comp 3 +allow the creation of pre-compiled extensible printf structures (performing +phase one of extensible printf processing). +These pre-compiled structures can then be passed to the printf variants in +.Xr xprintf_exec 3 +to produce the actual output (performing phases 2 and 3). +The compilation phase need only be done once, while execution can be performed +any number of times. +.Pp +A simple example of use is: +.Bd -literal + printf_comp_t pc = new_printf_comp(domain, loc, "%d: %C\en"); + for(i = 0; i = sizeof(coords) / sizeof(*coords); i++) { + xprintf_exec(pc, i, &coords[i]); + } + free_printf_comp(pc); +.Ed +.Pp +Here, +.Va coords +is a array containing +.Vt Coordinate +structures that are to be printed and the +.Va domain +and +.Va loc +variables are as from +.Sx EXAMPLE +above. +(Error checking on the return value from +.Fn new_printf_comp +is not shown). +.Sh SEE ALSO +.Xr printf 3 , +.Xr xlocale 3 , +.Xr xprintf 3 , +.Xr xprintf_comp 3 , +.Xr xprintf_domain 3 , +.Xr xprintf_exec 3 diff --git

the first is a pointer to the data to +dump, while the second argument is the length of the data, given as type +.Vt unsigned . +Normally, 16 characters are displayed per line, as pairs of hex characters +separated by spaces. +Specifying a field width less than 16 will display that number of characters +per line. +Setting the +.Sq Li + +(showsign) flag will prefix each line with the hex offset of the beginning +character in that line. +Setting the +.Sq Li # +(alternate form) flag will postfix an ASCII representation to each line, with +.Sq Li \&. +representing non-printable characters. +.It Li M +Errno. +The +.Sq Li M +specifier displayed the text representation of the given +.Vt int +argument, expected to be a valid +.Va errno +value (as returned by +.Xr strerror 3 ) . +Invalid errno values are represent by the +.Dq Li errno= +string followed by the decimal and hex values of the argument. +.It Li Q +Quoted. +The +.Sq Li Q +specifier displays a null-terminated string argument as a C string, with +leading and trailing double quotes. +Newlines, carriage-returns and tabs are represented by +.Sq Li \en , +.Sq Li \er +and +.Sq Li \et , +respectively, while backslashes and double quotes are preceeded with a +backslash. +All other whitespace characters not including space itself (those in which +.Xr isspace 3 +returns true) are displayed as octal escape sequences (a backslash followed by +three octal digits). +All other characters print as themselves. +.It Li T +time_t/timeval/timespec. +The +.Sq Li T +specifier displays the three types of time values as a single decimal value. +The argument should be a pointer to the time value to be converted. +Setting the appropriate flags indicates which type is indicated: +.Bl -tag -width ".Pq none" +.It Li ll +The +.Sq Li ll +(long long) flag indicates the argument points to a +.Vt struct timespec +structure. +The default precision is 9. +.It Li l +The +.Sq Li l +(long) flag indicates the argument points to a +.Vt struct timeval +structure. +The default precision is 6. +.It Pq none +By default, the argument points to a +.Vt time_t +value. +The default precision is 0 (the fractional part is not displayed). +.El +.Pp +If the +.Sq Li # +(alternate form) flag is specified, the value is displayed in years, days, +hours, minutes and seconds, as in: +.Dq Li 3y123d21h59m59s.987654 +(zero values are not displayed at all). +Note that the years are 365 days (no leap days). +.It Li V +String vis. +The +.Sq Li V +specifier uses +.Xr strvisx 3 +to display the null-terminated C string argument. +The precision value can be used to limit the amount of the string that is +processed (defaults to the entire string). +.Pp +Flag values can be used to obtain different encodings: +.Bl -tag -width "(none)" +.It Li + +The +.Sq Li + +(showsign) flag uses the +.Dq Li VIS_WHITE | VIS_HTTPSTYLE +flag value to +.Xr strvisx 3 . +.It Li 0 +The +.Sq Li 0 +(leading zero) flag uses the +.Dq Li VIS_WHITE | VIS_OCTAL +flag value to +.Xr strvisx 3 . +.It Li # +The +.Sq Li # +(alternate form) flag uses the +.Dq Li VIS_WHITE +flag value to +.Xr strvisx 3 . +.It Pq none +The default flag value to +.Xr strvisx 3 +is +.Dq Li VIS_WHITE | VIS_CSTYLE | VIS_OCTAL . +.El +.El +.Sh RETURN VALUES +The +.Fn new_printf_domain +and +.Fn copy_printf_domain +functions return the new domain, or +.Dv NULL +on failure (usually out of memory condition). +.Pp +The +.Fn register_printf_domain_function +and +.Fn register_printf_domain_render_std +return zero on success and \-1 on failure (usually due to an improper specifier +character or out of memory condition). +.Sh SEE ALSO +.Xr printf 3 , +.Xr strvisx 3 , +.Xr xprintf 3 , +.Xr xprintf_comp 3 , +.Xr xprintf 5 diff --git a/stdio/xprintf_domain.c b/stdio/xprintf_domain.c new file mode 100644 index 0000000..468f7ad --- /dev/null +++ b/stdio/xprintf_domain.c @@ -0,0 +1,250 @@ +/* + * Copyright (c) 2012 Apple Inc.

In addition to the standard + * rand()/srand() like interface, this package also has a special state info + * interface. The initstate() routine is called with a seed, an array of + * bytes, and a count of how many bytes are being passed in; this array is + * then initialized to contain information for random number generation with + * that much state information. Good sizes for the amount of state + * information are 32, 64, 128, and 256 bytes. The state can be switched by + * calling the setstate() routine with the same array as was initiallized + * with initstate(). By default, the package runs with 128 bytes of state + * information and generates far better random numbers than a linear + * congruential generator. If the amount of state information is less than + * 32 bytes, a simple linear congruential R.N.G. is used. + * + * Internally, the state information is treated as an array of uint32_t's; the + * zeroeth element of the array is the type of R.N.G. being used (small + * integer); the remainder of the array is the state information for the + * R.N.G. Thus, 32 bytes of state information will give 7 ints worth of + * state information, which will allow a degree seven polynomial. (Note: + * the zeroeth word of state information also has some other information + * stored in it -- see setstate() for details). + * + * The random number generation technique is a linear feedback shift register + * approach, employing trinomials (since there are fewer terms to sum up that + * way). In this approach, the least significant bit of all the numbers in + * the state table will act as a linear feedback shift register, and will + * have period 2^deg - 1 (where deg is the degree of the polynomial being + * used, assuming that the polynomial is irreducible and primitive). The + * higher order bits will have longer periods, since their values are also + * influenced by pseudo-random carries out of the lower bits. The total + * period of the generator is approximately deg*(2**deg - 1); thus doubling + * the amount of state information has a vast influence on the period of the + * generator. Note: the deg*(2**deg - 1) is an approximation only good for + * large deg, when the period of the shift is the dominant factor. + * With deg equal to seven, the period is actually much longer than the + * 7*(2**7 - 1) predicted by this formula. + * + * Modified 28 December 1994 by Jacob S. Rosenberg. + * The following changes have been made: + * All references to the type u_int have been changed to unsigned long. + * All references to type int have been changed to type long. Other + * cleanups have been made as well. A warning for both initstate and + * setstate has been inserted to the effect that on Sparc platforms + * the 'arg_state' variable must be forced to begin on word boundaries. + * This can be easily done by casting a long integer array to char *. + * The overall logic has been left STRICTLY alone. This software was + * tested on both a VAX and Sun SpacsStation with exactly the same + * results. The new version and the original give IDENTICAL results. + * The new version is somewhat faster than the original. As the + * documentation says: "By default, the package runs with 128 bytes of + * state information and generates far better random numbers than a linear + * congruential generator. If the amount of state information is less than + * 32 bytes, a simple linear congruential R.N.G. is used."

The uuid will +be generated based on high-quality randomness from +.IR /dev/urandom , +if available. If it is not available, then +.B uuid_generate +will use an alternative algorithm which uses the current time, the +local ethernet MAC address (if available), and random data generated +using a pseudo-random generator. +.sp +The +.B uuid_generate_random +function forces the use of the all-random UUID format, even if +a high-quality random number generator (i.e., +.IR /dev/urandom ) +is not available, in which case a pseudo-random +generator will be subsituted. Note that the use of a pseudo-random +generator may compromise the uniqueness of UUID's +generated in this fashion. +.sp +The +.B uuid_generate_time +function forces the use of the alternative algorithm which uses the +current time and the local ethernet MAC address (if available). +This algorithm used to be the default one used to generate UUID, but +because of the use of the ethernet MAC address, it can leak +information about when and where the UUID was generated. This can cause +privacy problems in some applications, so the +.B uuid_generate +function only uses this algorithm if a high-quality source of +randomness is not available. +.sp +The UUID is 16 bytes (128 bits) long, which gives approximately 3.4x10^38 +unique values (there are approximately 10^80 elemntary particles in +the universe according to Carl Sagan's +.IR Cosmos ). +The new UUID can reasonably be considered unique among all UUIDs created +on the local system, and among UUIDs created on other systems in the past +and in the future. +.SH RETURN VALUE +The newly created UUID is returned in the memory location pointed to by +.IR out . +.SH "CONFORMING TO" +OSF DCE 1.1 +.SH AUTHOR +Theodore Y.
