GIVFuncInfo* g_object_info_find_vfunc (GIObjectInfo* info,
gchar* name);
Locate a virtual function slot with name @name. Note that the namespace for virtuals is distinct from that of methods; there may or may not be a concrete method associated for a virtual. If there is one, it may be retrieved using g_vfunc_info_get_invoker(), otherwise %NULL will be returned. See the documentation for g_vfunc_info_get_invoker() for more information on invoking virtuals.
g_base_info_unref() when done.
