详细描述

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.

Matching places between managers for an example on how to use a match reply.
