*
*
* Module: pthread.h
*
* Purpose:
* Provides an implementation of PThreads based upon the
* standard:
*
* POSIX 1003.1-2001
* and
* The Single Unix Specification version 3
*
* (these two are equivalent)
*
* in order to enhance code portability between Windows,
* various commercial Unix implementations, and Linux.
*
* See the ANNOUNCE file for a full list of conforming
* routines and defined constants, and a list of missing
* routines and constants not defined in this implementation.
*
* Authors:
* There have been many contributors to this library.
* The initial implementation was contributed by
* John Bossom, and several others have provided major
* sections or revisions of parts of the implementation.
* Often significant effort has been contributed to
* find and fix important bugs and other problems to
* improve the reliability of the library, which sometimes
* is not reflected in the amount of code which changed as
* result.
* As much as possible, the contributors are acknowledged
* in the ChangeLog file in the source code distribution
* where their changes are noted in detail.
*
* Contributors are listed in the CONTRIBUTORS file.
*
* As usual, all bouquets go to the contributors, and all
* brickbats go to the project maintainer.
*
* Maintainer:
* The code base for this project is coordinated and
* eventually pre-tested, packaged, and made available by
*
* Ross Johnson <rpj@callisto.canberra.edu.au>
*
* QA Testers:
* Ultimately, the library is tested in the real world by
* a host of competent and demanding scientists and
* engineers who report bugs and/or provide solutions
* which are then fixed or incorporated into subsequent
* versions of the library. Each time a bug is fixed, a
* test case is written to prove the fix and ensure
* that later changes to the code don't reintroduce the
* same error. The number of test cases is slowly growing
* and therefore so is the code reliability.
*
* Compliance:
* See the file ANNOUNCE for the list of implemented
* and not-implemented routines and defined options.
* Of course, these are all defined is this file as well.
*
* Web site:
* The source code and other information about this library
* are available from
*
* http://sources.redhat.com/pthreads-win32/

* POSIX 1003.1-2001 Options
* =========================
*
* Options are normally set in <unistd.h>, which is not provided
* with pthreads-embedded.
*
* For conformance with the Single Unix Specification (version 3), all of the
* options below are defined, and have a value of either -1 (not supported)
* or 200112L (supported).
*
* These options can neither be left undefined nor have a value of 0, because
* either indicates that sysconf(), which is not implemented, may be used at
* runtime to check the status of the option.
*
* _POSIX_THREADS (== 200112L)
* If == 200112L, you can use threads
*
* _POSIX_THREAD_ATTR_STACKSIZE (== 200112L)
* If == 200112L, you can control the size of a thread's
* stack
* pthread_attr_getstacksize
* pthread_attr_setstacksize
*
* _POSIX_THREAD_ATTR_STACKADDR (== -1)
* If == 200112L, you can allocate and control a thread's
* stack. If not supported, the following functions
* will return ENOSYS, indicating they are not
* supported:
* pthread_attr_getstackaddr
* pthread_attr_setstackaddr
*
* _POSIX_THREAD_PRIORITY_SCHEDULING (== -1)
* If == 200112L, you can use realtime scheduling.
* This option indicates that the behaviour of some
* implemented functions conforms to the additional TPS
* requirements in the standard. E.g. rwlocks favour
* writers over readers when threads have equal priority.
*
* _POSIX_THREAD_PRIO_INHERIT (== -1)
* If == 200112L, you can create priority inheritance
* mutexes.
* pthread_mutexattr_getprotocol +
* pthread_mutexattr_setprotocol +
*
* _POSIX_THREAD_PRIO_PROTECT (== -1)
* If == 200112L, you can create priority ceiling mutexes
* Indicates the availability of:
* pthread_mutex_getprioceiling
* pthread_mutex_setprioceiling
* pthread_mutexattr_getprioceiling
* pthread_mutexattr_getprotocol +
* pthread_mutexattr_setprioceiling
* pthread_mutexattr_setprotocol +
*
* _POSIX_THREAD_PROCESS_SHARED (== -1)
* If set, you can create mutexes and condition
* variables that can be shared with another
* process.If set, indicates the availability
* of:
* pthread_mutexattr_getpshared
* pthread_mutexattr_setpshared
* pthread_condattr_getpshared
* pthread_condattr_setpshared
*
* _POSIX_THREAD_SAFE_FUNCTIONS (== 200112L)
* If == 200112L you can use the special *_r library
* functions that provide thread-safe behaviour
*
* _POSIX_READER_WRITER_LOCKS (== 200112L)
* If == 200112L, you can use read/write locks
*
* _POSIX_SPIN_LOCKS (== 200112L)
* If == 200112L, you can use spin locks
*
* _POSIX_BARRIERS (== 200112L)
* If == 200112L, you can use barriers
*
* + These functions provide both 'inherit' and/or
* 'protect' protocol, based upon these macro
* settings.
