FcDirCacheRead - Man Page

#include <fontconfig/fontconfig.h>

FcCache * FcDirCacheRead (const FcChar8 *dir, FcBool force, FcConfig *config);

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.
