If the operation is successful, the number of places in the reply matches those in the request. If a particular place in the request is not found, a default constructed place is used as a place holder in the reply. In this way, there is always a one is to one relationship between input places in the request, and output places in the reply.
If the operation is not successful the number of places is always zero.
