+/*
+ * 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.
+ *
+ *
+ * Please see the file LICENSE.txt in the source's root directory.

+ * \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.

+ *      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...

+ *  call, though, so you should call this once at startup and copy the string
+ *  if you need it.
+ *

+ *  place to write files (and that PHYSFS_getUserDir() and PHYSFS_getBaseDir(),
