NAMESYNOPSIS
DESCRIPTION
NAME
FcDirSave - DEPRECATED: formerly used to save a directory cache
SYNOPSIS
#include <fontconfig/fontconfig.h>
FcBool FcDirSave (FcFontSet * set , FcStrSet * dirs , const FcChar8 * dir );
DESCRIPTION
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.
