do something like that:
static int _fontconfig_init_count = 0;
int FcIni()
{
if (!_fontconfig_init_count)
{
/* do what is needed during the first call of initialization */
}
return ++_fontconfig_init_count;
}
int FcFini()
{
--_fontconfig_init_count;
if (!_fontconfig_init_count)
{
/* do what is needed during finalization */
}
return _fontconfig_init_count;
}
