Cross-Platform File API
|
|
|
|
XP_File INTERFACE IS A COMMONLY MISUNDERSTOOD API.PLEASE READ THESE
|
|
DOCS BEFORE USING THE API. The API is not self-documenting in any way,
|
|
and broken in many.
|
|
|
|
XP_File mimics the stdio file interface (fopen, fread & friends...).
|
|
The main difference is that to specify a file location, XP_File
|
|
uses a name in combination with an enum XP_FileType instead of full path.
|
|
|
|
For example :
|
|
stdio: fopen(filename, permissions)
|
|
maps to xp_file: XP_FileOpen (name, XP_FileType type, XP_FilePerm permissions);
|
|
|
|
Meaning of the name argument depends on the XP_FileType it is used with.
|
|
|
|
For example:
|
|
A) XP_FileOpen(name, xpURL)
|
|
name is the URL path to the file (/Drive/file.html)
|
|
B) XP_FileOpen(name, xpCache)
|
|
name is the partial path from cache directory (expands to cache-directory/name)
|
|
C) XP_FileOpen(name, xpTemporary)
|
|
name is the partial path from temporary directory (expands to cache-directory/name)
|
|
|
|
Corollary: YOU CANNOT MIX AND MATCH NAMES AND TYPES
|
|
For example:
|
|
newTempFile = XP_TempName(name, xpTemporary);
|
|
file = XP_FileOpen(newTempFile, xpURL, "r+w"); // BAD!, you've just mixed xpURL and xpTemporary
|
|
This is a very common error. It might work on some platforms, but it'll break others.
|
|
|
|
FILE NAME MADNESS
|
|
|
|
There are 3 basic ways to specify a file in the XP_File interface:
|
|
|
|
TheXP_FileSpec
|
|
|
|
char* - XP_FileType pair: used in most XP_File calls. the meaning of the name
|
|
depends on the enum. Common ones are:
|
|
XP_FileType / name means:
|
|
|
|
xpTemporary partial path relative to temporary directory
|
|
xpURL full path in the standard URL format (file://)
|
|
xpGlobalHistory name is ignored.
|
|
|
|
XP_FILE_NATIVE_PATH
|
|
|
|
char * used in platform-specific code, platform-specific full path
|
|
Windows: "C:\Windows\regedit.exe"
|
|
X: "/h/users/atotic/home.html"
|
|
Mac: "Macintosh HD:System Folder:System"
|
|
|
|
XP_FILE_URL_PATH used in cross-platform code, when you need to manipulate the full path.
|
|
It is a full path in the standard URL format: (file://<path>, but just the <path> part)
|
|
|
|
XP_FILE_NATIVE_PATH and XP_FILE_URL_PATH are often confused
|
|
|
|
To convert between these types:
|
|
|
|
Conversion: TheXP_FileSpec -> XP_FILE_NATIVE_PATH
|
|
Call: WH_FileName(name, type)
|
|
Example: WH_FileName("myName", xpTemporary) -> "/u/tmp/myName" on Unix
|
|
-> "C:\tmp\myName" on Windows
|
|
-> "Mac HD:Temporary folder:myName" on Mac
|
|
|
|
Conversion: XP_FILE_NATIVE_PATH -> XP_FILE_URL_PATH
|
|
Call: XP_PlatformFileToURL(name)
|
|
Example: Windows: XP_PlatformFileToURL("C:\tmp\myName") -> "file:///C|/tmp/myName"
|
|
Unix: XP_PlatformFileToURL(/u/tmp/myName") -> "file:///u/tmp/myName"
|
|
Mac: XP_PlatformFileToURL("Mac HD:Temporary folder:myName") -> "file:///Mac%20HD/Temporary%20folder/myName"
|
|
|
|
You cannot convert anything into arbitrary TheXP_FileSpec, but you can use the XP_FILE_URL_PATH
|
|
in combination with xpURL enum.
|
|
Example: XP_FileOpen("C|/tmp/myName", xpURL) works
|
|
|
|
COMMONLY USED CALLS NOT IN STDIO:
|
|
|
|
WH_FileName(name, XP_FileType) - maps TheXP_FileSpec pair to XP_FILE_NATIVE_PATH.
|
|
Use it when you need access to full paths in platform-specific code. For example:
|
|
For example:
|
|
cacheName = XP_FileName("", xpCacheFAT);
|
|
fopen(cacheName);
|
|
|
|
|
|
EXTENSIONS TO STDIO API:
|
|
|
|
- XP_FileRename also moves files accross file systems (copy + delete)
|
|
|
|
|
|
MISC API NOTES:
|
|
|
|
The names of most of the calls are derived by prepending stdio call name
|
|
with XP_File. (open -> XP_FileOpen, opendir -> XP_FileOpenDir). But warren
|
|
was fixing up some bugs near the end of 3.0, and in his infinite wisdom renamed
|
|
a few of them to WH_ instead of XP_. So, XP_FileName became WH_FileName. WH_ stands
|
|
for Warren Harris. Whatever...
|
|
|
|
Calls are not documented well. Most of the docs are in this header file. You
|
|
can usually get a hint about what the call should do by looking up the man
|
|
pages of the equivalent stdio call.
|
|
|
|
OLD DOCS (May mislead you, read at your peril!):
|
|
Macintosh file system is not organized in the same hierarchy as UNIX and PC
|
|
':' is a separator character instead of '/', '~', '/../' constructs do not
|
|
work. Basically, you cannot easily open a file using a pathname.
|
|
Because different types of files need to be stored in different
|
|
directories, the XP_FileOpen API takes a file type and file name as an
|
|
argument. Semantics of how file is opened vary with type.
|
|
|
|
"Personal" files are stored in the user's "home" directory (~ on unix,
|
|
launch point or system folder on Mac, dunno about Windows). File names
|
|
may be ignored since there's no reason for multiple personal files.
|
|
"Temporary" files are stored in /tmp or the equivalent
|
|
"URL" is the only type that allows access to anywhere on the disk
|
|
|
|
File Type File name Semantics
|
|
xpURL url part after file:/// Platform specific
