GdkPixbuf::save() override

I have write an overrid for GdkPixbuf::save() %% override gdk_pixbuf_save PHP_METHOD { char *filename; char *type; char **option_keys = NULL; char **option_values = NULL; GError *error = NULL; int argc,i,options; zval ***args; NOT_STATIC_METHOD();

       efree(args);
       WRONG_PARAM_COUNT;

} else if(argc%2) {
