gi_object_info_find_vfunc_using_interfaces (
  GIObjectInfo* info,
  const char* name,
  GIBaseInfo** declarer


Locate a virtual function slot with name name, searching both the object info and any interfaces it implements.

NULL will be returned if there’s no vfunc available with that 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 gi_vfunc_info_get_invoker(), otherwise that method will return NULL.

Note that this function does not search parent classes; you will have to chain up if that’s desired.
