NAME
       FcConfigReference - Increment config reference count

SYNOPSIS
       #include <fontconfig/fontconfig.h>

       FcConfig * FcConfigReference (FcConfig *config);

DESCRIPTION
       Add  another  reference to config. Configs are freed only when the reference count reaches
       zero.  If config is NULL, the current configuration is used.  In that case  this  function
       will  be  similar  to  FcConfigGetCurrent()  except that it increments the reference count
       before returning and the user is responsible for destroying  the  configuration	when  not
       needed anymore.

VERSION
       Fontconfig version 2.10.95
