I think the documentation for "PHYSFS_enumerateFiles" indicates that NO
directory names will be returned in the array.
From the docs:
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" [snip]
* We've got [x.sav].
* We've got [y.sav].
* We've got [z.sav].
* We've got [w.sav].
So, here you have in the search path
and the following files:
and it clearly isn't showing "savegames" or even ".", ".." in the list
which would of course exist on (some?) file systems.
I don't think this function is going to do what you need. Perhaps you
could use playlists which indicate where the files are stored?
Also, another point is that the docs say: "We only promise there will
be no duplicates"
so if you had
C:\foo\Ace of Base - All That She Wants.MP3
C:\myMp3s\Ace of Base - All That She Wants.MP3
I *think* you would only get one song returned, even though the two
files may be different remixes. I haven't tested this though.
