You can do this with a return type of already_AddRefed<nsIMutableArray>. Then instead of list.forget(_retval); return NS_OK; you do just return list.forget(); Note that in this case you cannot ignore the return value -- it must be assigned to an nsCOMPtr or a RefPtr, or else it will leak. Ideally we would allow a return type of nsCOMPtr<nsIMutableArray>&&, but currently I think we don't. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
