FcConfigParseAndLoad - load a configuration file
#include <fontconfig/fontconfig.h>
FcBool FcConfigParseAndLoad (FcConfig *config, const FcChar8 *file, FcBool complain);
Walks the configuration in 'file' and constructs the internal
representation in 'config'. Any include files referenced from within 'file'
will be loaded and parsed. If 'complain' is FcFalse, no warning will be
displayed if 'file' does not exist. Error and warning messages will be
output to stderr. Returns FcFalse if some error occurred while loading the
file, either a parse error, semantic error or allocation failure. Otherwise
returns FcTrue. After all configuration files / strings have been loaded,
with FcConfigParseAndLoad and/or
FcConfigParseAndLoadFromMemory, call FcConfigBuildFonts to
build the font database.
