       FcConfigFilename - Find a config file

       #include <fontconfig.h>

       char * FcConfigFilename (const char *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.
