FcDirSave - DEPRECATED: formerly used to save a directory cache
FcBool FcDirSave (FcFontSet *set, FcStrSet *dirs, const FcChar8 *dir);
This function now does nothing aside from returning FcFalse. It used to
creates the per-directory cache file for dir and populates it with the
fonts in set and subdirectories in dirs. All of this functionality is
now automatically managed by FcDirCacheLoad and FcDirCacheRead.
