FcConfigGetFonts − Get config font set
FcFontSet * FcConfigGetFonts (FcConfig *config, FcSetName set);
Returns one of the two sets of fonts from the configuration as specified by set. This font set is owned by the library and must not be modified or freed. If config is NULL, the current configuration is used.
This function isn’t MT-safe. FcConfigReference must be called before using this and then FcConfigDestroy when the return value is no longer referenced.
