game programming library.
int al_findnext(struct al_ffblk *info);
This finds the next file in a search started by al_findfirst(). Example:
if (al_findfirst("*.pcx", &info, 0) != 0)
/* Do something useful here with info.name. */
} while (al_findnext(&info) == 0);
Returns zero if a match is found, non-zero if none is found or if an error
occurred and, in the latter case, sets errno accordingly.
