/**
* \mainpage PhysicsFS globbing
*
* This is an extension to PhysicsFS to let you search for files with basic
* wildcard matching, regardless of what sort of filesystem or archive they
* reside in. It does this by enumerating directories as needed and manually
* locating matching entries.
*
* Usage: Set up PhysicsFS as you normally would, then use
* PHYSFSEXT_enumerateFilesPattern() when enumerating files. This is just
* like PHYSFS_enumerateFiles(), but it returns a subset that matches your
* wildcard pattern. You must call PHYSFS_freeList() on the results, just
* like you would with PHYSFS_enumerateFiles().
*
* License: this code is public domain. I make no warranty that it is useful,
* correct, harmless, or environmentally safe.
*
* This particular file may be used however you like, including copying it
* verbatim into a closed-source project, exploiting it commercially, and
* removing any trace of my name from the source (although I hope you won't
* do that). I welcome enhancements and corrections to this file, but I do
* not require you to send me patches if you make changes. This code has
* NO WARRANTY.
*
* Unless otherwise stated, the rest of PhysicsFS falls under the zlib license.
* Please see LICENSE.txt in the root of the source tree.

/**
* \fn char **PHYSFS_enumerateFilesWildcard(const char *dir, const char *wildcard, int caseSensitive)
* \brief 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.txt", and there is also a "C:\userdir" in the search path
* that has a "savegames" subdirectory with "w.sav", then the following code:
*
* \code
* char **rc = PHYSFS_enumerateFilesWildcard("savegames", "*.sav", 0);
* char **i;
*
* for (i = rc; *i != NULL; i++)
* printf(" * We've got [%s].\n", *i);
*
* PHYSFS_freeList(rc);
* \endcode
*
* ...will print:
*
* \verbatim
* We've got [x.sav].
* We've got [y.Sav].
* We've got [w.sav].\endverbatim
*
* 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.
*
* Wildcard strings can use the '*' and '?' characters, currently.
* Matches can be case-insensitive if you pass a zero for argument 3.
*
* Don't forget to call PHYSFS_freeList() with the return value from this
* function when you are done with it.
*
* \param dir directory in platform-independent notation to enumerate.
* \return Null-terminated array of null-terminated strings.
