Will it be better to pass object ops to get_req_object_attributes() and update the usages accordingly? Possibly allowing NULL which will default to directory.

Or actually I can better just use get_handle_obj() without specifying any ops in get_req_object_attributes().

Yes, that's what I meant. It should fail later when trying to link an object into something that's not a directory. -- Alexandre Julliard julliard(a)winehq.org
