FcDirCacheRead - read or construct a directory cache
#include <fontconfig.h>
FcCache * FcDirCacheRead(const FcChar8 *dir);
(FcBool force);
(FcConfig *config);
.fi
This returns a cache for dir. If force is FcFalse, then an existing,
valid cache file will be used. Otherwise, a new cache will be created
by scanning the directory and that returned.
