+ * GRP support routines for PhysicsFS.
+ *
+ * This driver handles BUILD engine archives ("groupfiles"). This format
+ * (but not this driver) was put together by Ken Silverman.
+ *
+ * The format is simple enough. In Ken's words:
+ *
+ * What's the .GRP file format?
+ *
+ * The ".grp" file format is just a collection of a lot of files stored
+ * into 1 big one. I tried to make the format as simple as possible: The
+ * first 12 bytes contains my name, "KenSilverman". The next 4 bytes is
+ * the number of files that were compacted into the group file. Then for
+ * each file, there is a 16 byte structure, where the first 12 bytes are
+ * the filename, and the last 4 bytes are the file's size. The rest of
+ * the group file is just the raw data packed one after the other in the
+ * same order as the list of files.
+ *
+ * (That info is from http://www.advsys.net/ken/build.htm ...)

+ * WAD support routines for PhysicsFS.
+ *
+ * This driver handles DOOM engine archives ("wads").
+ * This format (but not this driver) was designed by id Software for use
+ * with the DOOM engine.
+ * The specs of the format are from the unofficial doom specs v1.666
+ * found here: http://www.gamers.org/dhs/helpdocs/dmsp1666.html
+ * The format of the archive: (from the specs)
+ *
+ * A WAD file has three parts:
+ * (1) a twelve-byte header
+ * (2) one or more "lumps"
+ * (3) a directory or "info table" that contains the names, offsets, and
+ * sizes of all the lumps in the WAD
+ *
+ * The header consists of three four-byte parts:
+ * (a) an ASCII string which must be either "IWAD" or "PWAD"
+ * (b) a 4-byte (long) integer which is the number of lumps in the wad
+ * (c) a long integer which is the file offset to the start of
+ * the directory
+ *
+ * The directory has one 16-byte entry for every lump. Each entry consists
+ * of three parts:
+ *
+ * (a) a long integer, the file offset to the start of the lump
+ * (b) a long integer, the size of the lump in bytes
+ * (c) an 8-byte ASCII string, the name of the lump, padded with zeros.
+ * For example, the "DEMO1" entry in hexadecimal would be
+ * (44 45 4D 4F 31 00 00 00)
+ *
+ * Note that there is no way to tell if an opened WAD archive is a
+ * IWAD or PWAD with this archiver.
+ * I couldn't think of a way to provide that information, without being too
+ * hacky.
+ * I don't think it's really that important though.

+ * \mainpage PhysicsFS
+ *
+ * The latest version of PhysicsFS can be found at:
+ * http://icculus.org/physfs/
+ *
+ * PhysicsFS; a portable, flexible file i/o abstraction.
+ *
+ * This API gives you access to a system file system in ways superior to the
+ * stdio or system i/o calls. The brief benefits:
+ *
+ * - It's portable.
+ * - It's safe. No file access is permitted outside the specified dirs.
+ * - It's flexible. Archives (.ZIP files) can be used transparently as
+ * directory structures.
+ *
+ * This system is largely inspired by Quake 3's PK3 files and the related
+ * fs_* cvars. If you've ever tinkered with these, then this API will be
+ * familiar to you.
+ *
+ * With PhysicsFS, you have a single writing directory and multiple
+ * directories (the "search path") for reading. You can think of this as a
+ * filesystem within a filesystem. If (on Windows) you were to set the
+ * writing directory to "C:\MyGame\MyWritingDirectory", then no PHYSFS calls
+ * could touch anything above this directory, including the "C:\MyGame" and
+ * "C:\" directories. This prevents an application's internal scripting
+ * language from piddling over c:\\config.sys, for example. If you'd rather
+ * give PHYSFS full access to the system's REAL file system, set the writing
+ * dir to "C:\", but that's generally A Bad Thing for several reasons.
+ *
+ * Drive letters are hidden in PhysicsFS once you set up your initial paths.
+ * The search path creates a single, hierarchical directory structure.
+ * Not only does this lend itself well to general abstraction with archives,
+ * it also gives better support to operating systems like MacOS and Unix.
+ * Generally speaking, you shouldn't ever hardcode a drive letter; not only
+ * does this hurt portability to non-Microsoft OSes, but it limits your win32
+ * users to a single drive, too. Use the PhysicsFS abstraction functions and
+ * allow user-defined configuration options, too. When opening a file, you
+ * specify it like it was on a Unix filesystem: if you want to write to
+ * "C:\MyGame\MyConfigFiles\game.cfg", then you might set the write dir to
+ * "C:\MyGame" and then open "MyConfigFiles/game.cfg". This gives an
+ * abstraction across all platforms. Specifying a file in this way is termed
+ * "platform-independent notation" in this documentation. Specifying a
+ * a filename in a form such as "C:\mydir\myfile" or
+ * "MacOS hard drive:My Directory:My File" is termed "platform-dependent
+ * notation". The only time you use platform-dependent notation is when
+ * setting up your write directory and search path; after that, all file
+ * access into those directories are done with platform-independent notation.
+ *
+ * All files opened for writing are opened in relation to the write directory,
+ * which is the root of the writable filesystem. When opening a file for
+ * reading, PhysicsFS goes through the search path. This is NOT the
+ * same thing as the PATH environment variable. An application using
+ * PhysicsFS specifies directories to be searched which may be actual
+ * directories, or archive files that contain files and subdirectories of
+ * their own. See the end of these docs for currently supported archive
+ * formats.
+ *
+ * Once the search path is defined, you may open files for reading. If you've
+ * got the following search path defined (to use a win32 example again):
+ *
+ * - C:\\mygame
+ * - C:\\mygame\\myuserfiles
+ * - D:\\mygamescdromdatafiles
+ * - C:\\mygame\\installeddatafiles.zip
+ *
+ * Then a call to PHYSFS_openRead("textfiles/myfile.txt") (note the directory
+ * separator, lack of drive letter, and lack of dir separator at the start of
+ * the string; this is platform-independent notation) will check for
+ * C:\\mygame\\textfiles\\myfile.txt, then
+ * C:\\mygame\\myuserfiles\\textfiles\\myfile.txt, then
+ * D:\\mygamescdromdatafiles\\textfiles\\myfile.txt, then, finally, for
+ * textfiles\\myfile.txt inside of C:\\mygame\\installeddatafiles.zip.
+ * Remember that most archive types and platform filesystems store their
+ * filenames in a case-sensitive manner, so you should be careful to specify
+ * it correctly.
+ *
+ * Files opened through PhysicsFS may NOT contain "." or ".." or ":" as dir
+ * elements. Not only are these meaningless on MacOS Classic and/or Unix,
+ * they are a security hole. Also, symbolic links (which can be found in
+ * some archive types and directly in the filesystem on Unix platforms) are
+ * NOT followed until you call PHYSFS_permitSymbolicLinks(). That's left to
+ * your own discretion, as following a symlink can allow for access outside
+ * the write dir and search paths. For portability, there is no mechanism for
+ * creating new symlinks in PhysicsFS.
+ *
+ * The write dir is not included in the search path unless you specifically
+ * add it. While you CAN change the write dir as many times as you like,
+ * you should probably set it once and stick to it. Remember that your
+ * program will not have permission to write in every directory on Unix and
+ * NT systems.
+ *
+ * All files are opened in binary mode; there is no endline conversion for
+ * textfiles. Other than that, PhysicsFS has some convenience functions for
+ * platform-independence. There is a function to tell you the current
+ * platform's dir separator ("\\" on windows, "/" on Unix, ":" on MacOS),
+ * which is needed only to set up your search/write paths. There is a
+ * function to tell you what CD-ROM drives contain accessible discs, and a
+ * function to recommend a good search path, etc.
+ *
+ * A recommended order for the search path is the write dir, then the base dir,
+ * then the cdrom dir, then any archives discovered. Quake 3 does something
+ * like this, but moves the archives to the start of the search path. Build
+ * Engine games, like Duke Nukem 3D and Blood, place the archives last, and
+ * use the base dir for both searching and writing. There is a helper
+ * function (PHYSFS_setSaneConfig()) that puts together a basic configuration
+ * for you, based on a few parameters. Also see the comments on
+ * PHYSFS_getBaseDir(), and PHYSFS_getPrefDir() for info on what those
+ * are and how they can help you determine an optimal search path.
+ *
+ * PhysicsFS 2.0 adds the concept of "mounting" archives to arbitrary points
+ * in the search path. If a zipfile contains "maps/level.map" and you mount
+ * that archive at "mods/mymod", then you would have to open
+ * "mods/mymod/maps/level.map" to access the file, even though "mods/mymod"
+ * isn't actually specified in the .zip file. Unlike the Unix mentality of
+ * mounting a filesystem, "mods/mymod" doesn't actually have to exist when
+ * mounting the zipfile. It's a "virtual" directory. The mounting mechanism
+ * allows the developer to seperate archives in the tree and avoid trampling
+ * over files when added new archives, such as including mod support in a
+ * game...keeping external content on a tight leash in this manner can be of
+ * utmost importance to some applications.
+ *
+ * PhysicsFS is mostly thread safe. The error messages returned by
+ * PHYSFS_getLastError() are unique by thread, and library-state-setting
+ * functions are mutex'd. For efficiency, individual file accesses are
+ * not locked, so you can not safely read/write/seek/close/etc the same
+ * file from two threads at the same time. Other race conditions are bugs
+ * that should be reported/patched.
+ *
+ * While you CAN use stdio/syscall file access in a program that has PHYSFS_*
+ * calls, doing so is not recommended, and you can not use system
+ * filehandles with PhysicsFS and vice versa.
+ *
+ * Note that archives need not be named as such: if you have a ZIP file and
+ * rename it with a .PKG extension, the file will still be recognized as a
+ * ZIP archive by PhysicsFS; the file's contents are used to determine its
+ * type where possible.
+ *
+ * Currently supported archive types:
+ * - .ZIP (pkZip/WinZip/Info-ZIP compatible)
+ * - .7Z (7zip archives)
+ * - .ISO (ISO9660 files, CD-ROM images)
+ * - .GRP (Build Engine groupfile archives)
+ * - .PAK (Quake I/II archive format)
+ * - .HOG (Descent I/II HOG file archives)
+ * - .MVL (Descent II movielib archives)
+ * - .WAD (DOOM engine archives)
+ *
+ *
+ * String policy for PhysicsFS 2.0 and later:
+ *
+ * PhysicsFS 1.0 could only deal with null-terminated ASCII strings. All high
+ * ASCII chars resulted in undefined behaviour, and there was no Unicode
+ * support at all. PhysicsFS 2.0 supports Unicode without breaking binary
+ * compatibility with the 1.0 API by using UTF-8 encoding of all strings
+ * passed in and out of the library.
+ *
+ * All strings passed through PhysicsFS are in null-terminated UTF-8 format.
+ * This means that if all you care about is English (ASCII characters <= 127)
+ * then you just use regular C strings. If you care about Unicode (and you
+ * should!) then you need to figure out what your platform wants, needs, and
+ * offers. If you are on Windows before Win2000 and build with Unicode
+ * support, your TCHAR strings are two bytes per character (this is called
+ * "UCS-2 encoding"). Any modern Windows uses UTF-16, which is two bytes
+ * per character for most characters, but some characters are four. You
+ * should convert them to UTF-8 before handing them to PhysicsFS with
+ * PHYSFS_utf8FromUtf16(), which handles both UTF-16 and UCS-2. If you're
+ * using Unix or Mac OS X, your wchar_t strings are four bytes per character
+ * ("UCS-4 encoding"). Use PHYSFS_utf8FromUcs4(). Mac OS X can give you UTF-8
+ * directly from a CFString or NSString, and many Unixes generally give you C
+ * strings in UTF-8 format everywhere. If you have a single-byte high ASCII
+ * charset, like so-many European "codepages" you may be out of luck. We'll
+ * convert from "Latin1" to UTF-8 only, and never back to Latin1. If you're
+ * above ASCII 127, all bets are off: move to Unicode or use your platform's
+ * facilities. Passing a C string with high-ASCII data that isn't UTF-8
+ * encoded will NOT do what you expect!
+ *
+ * Naturally, there's also PHYSFS_utf8ToUcs2(), PHYSFS_utf8ToUtf16(), and
+ * PHYSFS_utf8ToUcs4() to get data back into a format you like. Behind the
+ * scenes, PhysicsFS will use Unicode where possible: the UTF-8 strings on
+ * Windows will be converted and used with the multibyte Windows APIs, for
+ * example.
+ *
+ * PhysicsFS offers basic encoding conversion support, but not a whole string
+ * library. Get your stuff into whatever format you can work with.
+ *
+ * All platforms supported by PhysicsFS 2.1 and later fully support Unicode.
+ * We have dropped platforms that don't (OS/2, Mac OS 9, Windows 95, etc), as
+ * even an OS that's over a decade old should be expected to handle this well.
+ * If you absolutely must support one of these platforms, you should use an
+ * older release of PhysicsFS.
+ *
+ * Many game-specific archivers are seriously unprepared for Unicode (the
+ * Descent HOG/MVL and Build Engine GRP archivers, for example, only offer a
+ * DOS 8.3 filename, for example). Nothing can be done for these, but they
+ * tend to be legacy formats for existing content that was all ASCII (and
+ * thus, valid UTF-8) anyhow. Other formats, like .ZIP, don't explicitly
+ * offer Unicode support, but unofficially expect filenames to be UTF-8
+ * encoded, and thus Just Work. Most everything does the right thing without
+ * bothering you, but it's good to be aware of these nuances in case they
+ * don't.
+ *

+ *
+ * Helper function.
+ *
+ * Get the "pref dir". This is meant to be where users can write personal
+ * files (preferences and save games, etc) that are specific to your
+ * application. This directory is unique per user, per application.
+ *
+ * This function will decide the appropriate location in the native filesystem,
+ * create the directory if necessary, and return a string in
+ * platform-dependent notation, suitable for passing to PHYSFS_setWriteDir().
+ *
+ * On Windows, this might look like:
+ * "C:\\Users\\bob\\AppData\\Roaming\\My Company\\My Program Name"
+ *
+ * On Linux, this might look like:
+ * "/home/bob/.local/share/My Program Name"
+ *
+ * On Mac OS X, this might look like:
+ * "/Users/bob/Library/Application Support/My Program Name"
+ *
+ * (etc.)
+ *
+ * You should probably use the pref dir for your write dir, and also put it
+ * near the beginning of your search path. Older versions of PhysicsFS
+ * offered only PHYSFS_getUserDir() and left you to figure out where the
+ * files should go under that tree. This finds the correct location
+ * for whatever platform, which not only changes between operating systems,
+ * but also versions of the same operating system.
+ *
+ * You specify the name of your organization (if it's not a real organization,
+ * your name or an Internet domain you own might do) and the name of your
+ * application. These should be proper names.
+ *
+ * Both the (org) and (app) strings may become part of a directory name, so
+ * please follow these rules:
+ *
+ * - Try to use the same org string (including case-sensitivity) for
+ * all your applications that use this function.
+ * - Always use a unique app string for each one, and make sure it never
+ * changes for an app once you've decided on it.
+ * - Unicode characters are legal, as long as it's UTF-8 encoded, but...
+ * - ...only use letters, numbers, and spaces. Avoid punctuation like
+ * "Game Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient.
+ *
+ * The pointer returned by this function remains valid until you call this
+ * function again, or call PHYSFS_deinit(). This is not necessarily a fast
+ * call, though, so you should call this once at startup and copy the string
+ * if you need it.
+ *
+ * You should assume the path returned by this function is the only safe
+ * place to write files (and that PHYSFS_getUserDir() and PHYSFS_getBaseDir(),
+ * while they might be writable, or even parents of the returned path, aren't
+ * where you should be writing things).
+ *
+ * \param org The name of your organization.
+ * \param app The name of your application.
+ * \return READ ONLY string of user dir in platform-dependent notation. NULL
+ * if there's a problem (creating directory failed, etc).
+ *
+ * \sa PHYSFS_getBaseDir
