Detailed Description

Define Documentation

#define PHYSFS_VERSION(x)

Value:

 {     (x)->major = PHYSFS_VER_MAJOR;     (x)->minor = PHYSFS_VER_MINOR;     (x)->patch = PHYSFS_VER_PATCH; }
 

Macro to determine PhysicsFS version program was compiled against.

This macro fills in a PHYSFS_Version structure with the version of the library you compiled against. This is determined by what header the compiler uses. Note that if you dynamically linked the library, you might have a slightly newer or older version at runtime. That version can be determined with PHYSFS_getLinkedVersion(), which, unlike PHYSFS_VERSION, is not a macro.

Parameters:

x A pointer to a PHYSFS_Version struct to initialize.

See also:

PHYSFS_Version
PHYSFS_getLinkedVersion

Typedef Documentation

PHYSFS_sint64

A signed, 64-bit integer type.

Warning:

on platforms without any sort of 64-bit datatype, this is equivalent to PHYSFS_sint32!

PHYSFS_uint64

An unsigned, 64-bit integer type.

Warning:

on platforms without any sort of 64-bit datatype, this is equivalent to PHYSFS_uint32!

Function Documentation

int PHYSFS_addToSearchPath (const char * newDir, int appendToPath)

Add an archive or directory to the search path.

If this is a duplicate, the entry is not added again, even though the function succeeds.

Parameters:

newDir directory or archive to add to the path, in platform-dependent notation.
appendToPath nonzero to append to search path, zero to prepend.

Returns:

nonzero if added to path, zero on failure (bogus archive, dir missing, etc). Specifics of the error can be gleaned from PHYSFS_getLastError().

See also:

PHYSFS_removeFromSearchPath
PHYSFS_getSearchPath

int PHYSFS_close (PHYSFS_file * handle)

Close a PhysicsFS filehandle.

This call is capable of failing if the operating system was buffering writes to the physical media, and, now forced to write those changes to physical media, can not store the data for some reason. In such a case, the filehandle stays open. A well-written program should ALWAYS check the return value from the close call in addition to every writing call!

Parameters:

handle handle returned from PHYSFS_open*().

Returns:

nonzero on success, zero on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

See also:

PHYSFS_openRead
PHYSFS_openWrite
PHYSFS_openAppend

int PHYSFS_deinit (void)

Deinitialize the PhysicsFS library.

This closes any files opened via PhysicsFS, blanks the search/write paths, frees memory, and invalidates all of your file handles.

Note that this call can FAIL if there's a file open for writing that refuses to close (for example, the underlying operating system was buffering writes to network filesystem, and the fileserver has crashed, or a hard drive has failed, etc). It is usually best to close all write handles yourself before calling this function, so that you can gracefully handle a specific failure.

Once successfully deinitialized, PHYSFS_init() can be called again to restart the subsystem. All defaults API states are restored at this point.

Returns:

nonzero on success, zero on error. Specifics of the error can be gleaned from PHYSFS_getLastError(). If failure, state of PhysFS is undefined, and probably badly screwed up.

See also:

PHYSFS_init

int PHYSFS_delete (const char * filename)

Delete a file or directory.

(filename) is specified in platform-independent notation in relation to the write dir.

A directory must be empty before this call can delete it.

Deleting a symlink will remove the link, not what it points to, regardless of whether you 'permitSymLinks' or not.

So if you've got the write dir set to 'C:\mygame\writedir' and call PHYSFS_delete('downloads/maps/level1.map') then the file 'C:\mygame\writedir\downloads\maps\level1.map' is removed from the physical filesystem, if it exists and the operating system permits the deletion.

Note that on Unix systems, deleting a file may be successful, but the actual file won't be removed until all processes that have an open filehandle to it (including your program) close their handles.

Chances are, the bits that make up the file still exist, they are just made available to be written over at a later point. Don't consider this a security method or anything. :)

Parameters:

filename Filename to delete.

Returns:

nonzero on success, zero on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

char ** PHYSFS_enumerateFiles (const char * dir)

Get a file listing of a search path's directory.

Matching directories are interpolated. That is, if 'C:\mydir' is in the search path and contains a directory 'savegames' that contains 'x.sav', 'y.sav', and 'z.sav', and there is also a 'C:\userdir' in the search path that has a 'savegames' subdirectory with 'w.sav', then the following code:

  char **rc = PHYSFS_enumerateFiles('savegames');
  char **i;
 
  for (i = rc; *i != NULL; i++)
      printf(' * We've got [%s]., *i);
 
  PHYSFS_freeList(rc);
 

 
  * We've got [x.sav].
  * We've got [y.sav].
  * We've got [z.sav].
  * We've got [w.sav]..fi
 
 
 Feel free to sort the list however you like. We only promise there will be no duplicates, but not what order the final list will come back in.
 
 Don't forget to call PHYSFS_freeList() with the return value from this function when you are done with it.
 
 Parameters:
 

dir directory in platform-independent notation to enumerate.

 
 Returns:
 

Null-terminated array of null-terminated strings.

 

int PHYSFS_eof (PHYSFS_file * handle)

Check for end-of-file state on a PhysicsFS filehandle.

Determine if the end of file has been reached in a PhysicsFS filehandle.

Parameters:

handle handle returned from PHYSFS_openRead().

Returns:

nonzero if EOF, zero if not.

See also:

PHYSFS_read
PHYSFS_tell

int PHYSFS_exists (const char * fname)

Determine if a file exists in the search path.

Reports true if there is an entry anywhere in the search path by the name of (fname).

Note that entries that are symlinks are ignored if PHYSFS_permitSymbolicLinks(1) hasn't been called, so you might end up further down in the search path than expected.

Parameters:

fname filename in platform-independent notation.

Returns:

non-zero if filename exists. zero otherwise.

See also:

PHYSFS_isDirectory
PHYSFS_isSymbolicLink

PHYSFS_sint64 PHYSFS_fileLength (PHYSFS_file * handle)

Get total length of a file in bytes.

Note that if the file size can't be determined (since the archive is 'streamed' or whatnot) than this will report (-1). Also note that if another process/thread is writing to this file at the same time, then the information this function supplies could be incorrect before you get it. Use with caution, or better yet, don't use at all.

Parameters:

handle handle returned from PHYSFS_open*().

Returns:

size in bytes of the file. -1 if can't be determined.

See also:

PHYSFS_tell
PHYSFS_seek

int PHYSFS_flush (PHYSFS_file * handle)

Flush a buffered PhysicsFS file handle.

For buffered files opened for writing, this will put the current contents of the buffer to disk and flag the buffer as empty if possible.

For buffered files opened for reading or unbuffered files, this is a safe no-op, and will report success.

Parameters:

handle handle returned from PHYSFS_open*().

Returns:

nonzero if successful, zero on error.

See also:

PHYSFS_setBuffer
PHYSFS_close

void PHYSFS_freeList (void * listVar)

Deallocate resources of lists returned by PhysicsFS.

Certain PhysicsFS functions return lists of information that are dynamically allocated. Use this function to free those resources.

Parameters:

listVar List of information specified as freeable by this function.

See also:

PHYSFS_getCdRomDirs
PHYSFS_enumerateFiles
PHYSFS_getSearchPath

const char * PHYSFS_getBaseDir (void)

Get the path where the application resides.

Helper function.

Get the 'base dir'. This is the directory where the application was run from, which is probably the installation directory, and may or may not be the process's current working directory.

You should probably use the base dir in your search path.

Returns:

READ ONLY string of base dir in platform-dependent notation.

See also:

PHYSFS_getUserDir

char ** PHYSFS_getCdRomDirs (void)

Get an array of paths to available CD-ROM drives.

The dirs returned are platform-dependent ('D:\' on Win32, '/cdrom' or whatnot on Unix). Dirs are only returned if there is a disc ready and accessible in the drive. So if you've got two drives (D: and E:), and only E: has a disc in it, then that's all you get. If the user inserts a disc in D: and you call this function again, you get both drives. If, on a Unix box, the user unmounts a disc and remounts it elsewhere, the next call to this function will reflect that change. Fun.

The returned value is an array of strings, with a NULL entry to signify the end of the list:

  char **cds = PHYSFS_getCdRomDirs();
  char **i;
 
  for (i = cds; *i != NULL; i++)
      printf('cdrom dir [%s] is available., *i);
 
  PHYSFS_freeList(cds);
 

This call may block while drives spin up. Be forewarned.

When you are done with the returned information, you may dispose of the resources by calling PHYSFS_freeList() with the returned pointer.

Returns:

Null-terminated array of null-terminated strings.

const char * PHYSFS_getDirSeparator (void)

Get platform-dependent dir separator string.

This returns '\\' on win32, '/' on Unix, and ':' on MacOS. It may be more than one character, depending on the platform, and your code should take that into account. Note that this is only useful for setting up the search/write paths, since access into those dirs always use '/' (platform-independent notation) to separate directories. This is also handy for getting platform-independent access when using stdio calls.

Returns:

READ ONLY null-terminated string of platform's dir separator.

const char * PHYSFS_getLastError (void)

Get human-readable error information.

Get the last PhysicsFS error message as a null-terminated string. This will be NULL if there's been no error since the last call to this function. The pointer returned by this call points to an internal buffer. Each thread has a unique error state associated with it, but each time a new error message is set, it will overwrite the previous one associated with that thread. It is safe to call this function at anytime, even before PHYSFS_init().

Returns:

READ ONLY string of last error message.

PHYSFS_sint64 PHYSFS_getLastModTime (const char * filename)

Get the last modification time of a file.

The modtime is returned as a number of seconds since the epoch (Jan 1, 1970). The exact derivation and accuracy of this time depends on the particular archiver. If there is no reasonable way to obtain this information for a particular archiver, or there was some sort of error, this function returns (-1).

Parameters:

filename filename to check, in platform-independent notation.

Returns:

last modified time of the file. -1 if it can't be determined.

void PHYSFS_getLinkedVersion (PHYSFS_Version * ver)

Get the version of PhysicsFS that is linked against your program.

If you are using a shared library (DLL) version of PhysFS, then it is possible that it will be different than the version you compiled against.

This is a real function; the macro PHYSFS_VERSION tells you what version of PhysFS you compiled against:

  PHYSFS_Version compiled;
  PHYSFS_Version linked;
 
  PHYSFS_VERSION(&compiled);
  PHYSFS_getLinkedVersion(&linked);
  printf('We compiled against PhysFS version %d.%d.%d ...,
            compiled.major, compiled.minor, compiled.patch);
  printf('But we linked against PhysFS version %d.%d.%d.,
            linked.major, linked.minor, linked.patch);
 

This function may be called safely at any time, even before PHYSFS_init().

See also:

PHYSFS_VERSION

const char * PHYSFS_getRealDir (const char * filename)

Figure out where in the search path a file resides.

The file is specified in platform-independent notation. The returned filename will be the element of the search path where the file was found, which may be a directory, or an archive. Even if there are multiple matches in different parts of the search path, only the first one found is used, just like when opening a file.

So, if you look for 'maps/level1.map', and C:\mygame is in your search path and C:\mygame\maps\level1.map exists, then 'C:\mygame' is returned.

If a any part of a match is a symbolic link, and you've not explicitly permitted symlinks, then it will be ignored, and the search for a match will continue.

Parameters:

filename file to look for.

Returns:

READ ONLY string of element of search path containing the the file in question. NULL if not found.

char ** PHYSFS_getSearchPath (void)

Get the current search path.

The default search path is an empty list.

The returned value is an array of strings, with a NULL entry to signify the end of the list:

  char **i;
 
  for (i = PHYSFS_getSearchPath(); *i != NULL; i++)
      printf('[%s] is in the search path., *i);
 

When you are done with the returned information, you may dispose of the resources by calling PHYSFS_freeList() with the returned pointer.

Returns:

Null-terminated array of null-terminated strings. NULL if there was a problem (read: OUT OF MEMORY).

See also:

PHYSFS_addToSearchPath
PHYSFS_removeFromSearchPath

const char * PHYSFS_getUserDir (void)

Get the path where user's home directory resides.

Helper function.

Get the 'user dir'. This is meant to be a suggestion of where a specific user of the system can store files. On Unix, this is her home directory. On systems with no concept of multiple home directories (MacOS, win95), this will default to something like 'C:\mybasedir\users\username' where 'username' will either be the login name, or 'default' if the platform doesn't support multiple users, either.

You should probably use the user dir as the basis for your write dir, and also put it near the beginning of your search path.

Returns:

READ ONLY string of user dir in platform-dependent notation.

See also:

PHYSFS_getBaseDir

const char * PHYSFS_getWriteDir (void)

Get path where PhysicsFS will allow file writing.

Get the current write dir. The default write dir is NULL.

Returns:

READ ONLY string of write dir in platform-dependent notation, OR NULL IF NO WRITE PATH IS CURRENTLY SET.

See also:

PHYSFS_setWriteDir

int PHYSFS_init (const char * argv0)

Initialize the PhysicsFS library.

This must be called before any other PhysicsFS function.

This should be called prior to any attempts to change your process's current working directory.

Parameters:

argv0 the argv[0] string passed to your program's mainline. This may be NULL on most platforms (such as ones without a standard main() function), but you should always try to pass something in here. Unix-like systems such as Linux _need_ to pass argv[0] from main() in here.

Returns:

nonzero on success, zero on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

See also:

PHYSFS_deinit

int PHYSFS_isDirectory (const char * fname)

Determine if a file in the search path is really a directory.

Determine if the first occurence of (fname) in the search path is really a directory entry.

Note that entries that are symlinks are ignored if PHYSFS_permitSymbolicLinks(1) hasn't been called, so you might end up further down in the search path than expected.

Parameters:

fname filename in platform-independent notation.

Returns:

non-zero if filename exists and is a directory. zero otherwise.

See also:

PHYSFS_exists
PHYSFS_isSymbolicLink

int PHYSFS_isSymbolicLink (const char * fname)

Determine if a file in the search path is really a symbolic link.

Determine if the first occurence of (fname) in the search path is really a symbolic link.

Note that entries that are symlinks are ignored if PHYSFS_permitSymbolicLinks(1) hasn't been called, and as such, this function will always return 0 in that case.

Parameters:

fname filename in platform-independent notation.

Returns:

non-zero if filename exists and is a symlink. zero otherwise.

See also:

PHYSFS_exists
PHYSFS_isDirectory

int PHYSFS_mkdir (const char * dirName)

Create a directory.

This is specified in platform-independent notation in relation to the write dir. All missing parent directories are also created if they don't exist.

So if you've got the write dir set to 'C:\mygame\writedir' and call PHYSFS_mkdir('downloads/maps') then the directories 'C:\mygame\writedir\downloads' and 'C:\mygame\writedir\downloads\maps' will be created if possible. If the creation of 'maps' fails after we have successfully created 'downloads', then the function leaves the created directory behind and reports failure.

Parameters:

dirName New dir to create.

Returns:

nonzero on success, zero on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

See also:

PHYSFS_delete

PHYSFS_file * PHYSFS_openAppend (const char * filename)

Open a file for appending.

Open a file for writing, in platform-independent notation and in relation to the write dir as the root of the writable filesystem. The specified file is created if it doesn't exist. If it does exist, the writing offset is set to the end of the file, so the first write will be the byte after the end.

Note that entries that are symlinks are ignored if PHYSFS_permitSymbolicLinks(1) hasn't been called, and opening a symlink with this function will fail in such a case.

Parameters:

filename File to open.

Returns:

A valid PhysicsFS filehandle on success, NULL on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

See also:

PHYSFS_openRead
PHYSFS_openWrite
PHYSFS_write
PHYSFS_close

PHYSFS_file * PHYSFS_openRead (const char * filename)

Open a file for reading.

Open a file for reading, in platform-independent notation. The search path is checked one at a time until a matching file is found, in which case an abstract filehandle is associated with it, and reading may be done. The reading offset is set to the first byte of the file.

Note that entries that are symlinks are ignored if PHYSFS_permitSymbolicLinks(1) hasn't been called, and opening a symlink with this function will fail in such a case.

Parameters:

filename File to open.

Returns:

A valid PhysicsFS filehandle on success, NULL on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

See also:

PHYSFS_openWrite
PHYSFS_openAppend
PHYSFS_read
PHYSFS_close

PHYSFS_file * PHYSFS_openWrite (const char * filename)

Open a file for writing.

Open a file for writing, in platform-independent notation and in relation to the write dir as the root of the writable filesystem. The specified file is created if it doesn't exist. If it does exist, it is truncated to zero bytes, and the writing offset is set to the start.

Note that entries that are symlinks are ignored if PHYSFS_permitSymbolicLinks(1) hasn't been called, and opening a symlink with this function will fail in such a case.

Parameters:

filename File to open.

Returns:

A valid PhysicsFS filehandle on success, NULL on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

See also:

PHYSFS_openRead
PHYSFS_openAppend

void PHYSFS_permitSymbolicLinks (int allow)

Enable or disable following of symbolic links.

Some physical filesystems and archives contain files that are just pointers to other files. On the physical filesystem, opening such a link will (transparently) open the file that is pointed to.

By default, PhysicsFS will check if a file is really a symlink during open calls and fail if it is. Otherwise, the link could take you outside the write and search paths, and compromise security.

If you want to take that risk, call this function with a non-zero parameter. Note that this is more for sandboxing a program's scripting language, in case untrusted scripts try to compromise the system. Generally speaking, a user could very well have a legitimate reason to set up a symlink, so unless you feel there's a specific danger in allowing them, you should permit them.

Symlinks are only explicitly checked when dealing with filenames in platform-independent notation. That is, when setting up your search and write paths, etc, symlinks are never checked for.

Symbolic link permission can be enabled or disabled at any time after you've called PHYSFS_init(), and is disabled by default.

Parameters:

allow nonzero to permit symlinks, zero to deny linking.

PHYSFS_sint64 PHYSFS_read (PHYSFS_file * handle, void * buffer, PHYSFS_uint32 objSize, PHYSFS_uint32 objCount)

Read data from a PhysicsFS filehandle.

The file must be opened for reading.

Parameters:

handle handle returned from PHYSFS_openRead().
buffer buffer to store read data into.
objSize size in bytes of objects being read from (handle).
objCount number of (objSize) objects to read from (handle).

Returns:

number of objects read. PHYSFS_getLastError() can shed light on the reason this might be < (objCount), as can PHYSFS_eof(). -1 if complete failure.

int PHYSFS_removeFromSearchPath (const char * oldDir)

Remove a directory or archive from the search path.

This must be a (case-sensitive) match to a dir or archive already in the search path, specified in platform-dependent notation.

This call will fail (and fail to remove from the path) if the element still has files open in it.

Parameters:

oldDir dir/archive to remove.

Returns:

nonzero on success, zero on failure. Specifics of the error can be gleaned from PHYSFS_getLastError().

int PHYSFS_setBuffer (PHYSFS_file * handle, PHYSFS_uint64 bufsize)

Set up buffering for a PhysicsFS file handle.

Define an i/o buffer for a file handle. A memory block of (bufsize) bytes will be allocated and associated with (handle).

For files opened for reading, up to (bufsize) bytes are read from (handle) and stored in the internal buffer. Calls to PHYSFS_read() will pull from this buffer until it is empty, and then refill it for more reading. Note that compressed files, like ZIP archives, will decompress while buffering, so this can be handy for offsetting CPU-intensive operations. The buffer isn't filled until you do your next read.

For files opened for writing, data will be buffered to memory until the buffer is full or the buffer is flushed. Closing a handle implicitly causes a flush...check your return values!

Seeking, etc transparently accounts for buffering.

You can resize an existing buffer by calling this function more than once on the same file. Setting the buffer size to zero will free an existing buffer.

PhysicsFS file handles are unbuffered by default.

Please check the return value of this function! Failures can include not being able to seek backwards in a read-only file when removing the buffer, not being able to allocate the buffer, and not being able to flush the buffer to disk, among other unexpected problems.

Parameters:

handle handle returned from PHYSFS_open*().
bufsize size, in bytes, of buffer to allocate.

Returns:

nonzero if successful, zero on error.

PHYSFS_read
PHYSFS_write

int PHYSFS_setSaneConfig (const char * organization, const char * appName, const char * archiveExt, int includeCdRoms, int archivesFirst)

Set up sane, default paths.

Helper function.

The write dir will be set to 'userdir/.organization/appName', which is created if it doesn't exist.

The above is sufficient to make sure your program's configuration directory is separated from other clutter, and platform-independent. The period before 'mygame' even hides the directory on Unix systems.

The search path will be:

*

The Write Dir (created if it doesn't exist)

*

The Base Dir (PHYSFS_getBaseDir())

*

All found CD-ROM dirs (optionally)

These directories are then searched for files ending with the extension (archiveExt), which, if they are valid and supported archives, will also be added to the search path. If you specified 'PKG' for (archiveExt), and there's a file named data.PKG in the base dir, it'll be checked. Archives can either be appended or prepended to the search path in alphabetical order, regardless of which directories they were found in.

All of this can be accomplished from the application, but this just does it all for you. Feel free to add more to the search path manually, too.

Parameters:

organization Name of your company/group/etc to be used as a dirname, so keep it small, and no-frills.
appName Program-specific name of your program, to separate it from other programs using PhysicsFS.
archiveExt File extension used by your program to specify an archive. For example, Quake 3 uses 'pk3', even though they are just zipfiles. Specify NULL to not dig out archives automatically. Do not specify the '.' char; If you want to look for ZIP files, specify 'ZIP' and not '.ZIP' ... the archive search is case-insensitive.
includeCdRoms Non-zero to include CD-ROMs in the search path, and (if (archiveExt) != NULL) search them for archives. This may cause a significant amount of blocking while discs are accessed, and if there are no discs in the drive (or even not mounted on Unix systems), then they may not be made available anyhow. You may want to specify zero and handle the disc setup yourself.
archivesFirst Non-zero to prepend the archives to the search path. Zero to append them. Ignored if !(archiveExt).

Returns:

nonzero on success, zero on error. Specifics of the error can be gleaned from PHYSFS_getLastError().

int PHYSFS_setWriteDir (const char * newDir)

Tell PhysicsFS where it may write files.

Set a new write dir. This will override the previous setting.

This call will fail (and fail to change the write dir) if the current write dir still has files open in it.

Parameters:

newDir The new directory to be the root of the write dir, specified in platform-dependent notation. Setting to NULL disables the write dir, so no files can be opened for writing via PhysicsFS.

Returns:

non-zero on success, zero on failure. All attempts to open a file for writing via PhysicsFS will fail until this call succeeds. Specifics of the error can be gleaned from PHYSFS_getLastError().

PHYSFS_getWriteDir

const PHYSFS_ArchiveInfo ** PHYSFS_supportedArchiveTypes (void)

Get a list of supported archive types.

Get a list of archive types supported by this implementation of PhysicFS. These are the file formats usable for search path entries. This is for informational purposes only. Note that the extension listed is merely convention: if we list 'ZIP', you can open a PkZip-compatible archive with an extension of 'XYZ', if you like.

The returned value is an array of pointers to PHYSFS_ArchiveInfo structures, with a NULL entry to signify the end of the list:

  PHYSFS_ArchiveInfo **i;
 
  for (i = PHYSFS_supportedArchiveTypes(); *i != NULL; i++)
  {
      printf('Supported archive: [%s], which is [%s].,
               i->extension, i->description);
  }
 

The return values are pointers to static internal memory, and should be considered READ ONLY, and never freed.

Returns:

READ ONLY Null-terminated array of READ ONLY structures.
