       FcConfigFilename - Find a config file


       #include <fontconfig.h>

       FcChar8 * FcConfigFilename(const FcChar8 *name);


       Given  the  specified  external  entity  name,  return  the  associated
       filename.   This  provides  applications  a  way  to  convert   various
       configuration file references into filename form.

       A  null  or  empty  name  indicates that the default configuration file
       should be used; which file this references can be overridden  with  the
       FC_CONFIG_FILE  environment  variable. Next, if the name starts with ~,
       it refers to a file in the current users home directory.  Otherwise  if
       the  name  doesn’t  start  with ’/’, it refers to a file in the default
       configuration  directory;  the  built-in  default  directory   can   be
       overridden with the FC_CONFIG_DIR environment variable.
