I believe so, although I don't think the contract requires this. For example it would seem to be contractually valid to not call the completion callback until much later, eg. nbd_close. Also, in addition to what Eric said in his reply, it is also possible for callbacks to set the error int (through the pointer) in order to cause an error to be returned.
