They are identical, except that tp_getattr takes a char*, when tp_getattro wants a PyObject*.

Yes. Fortunately, it's not often the case. > But I read > somewhere that "tp_getattr" was deprecated :-? ... Deprecated in favor of tp_getattro I presume. -- Amaury Forgeot d'Arc _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
