KnownDestCount (MQLONG)

This is the number of messages that the current MQPUT or MQPUT1 call has sent successfully to queues in the distribution list that are local queues. The count does not include messages sent to queues that resolve to remote queues (even though a local transmission queue is used initially to store the message). This field is also set when putting a message to a single queue that is not in a distribution list.

This is an output field. The initial value of this field is 0. This field is not set if Version is less than MQPMO_VERSION_1.

This field is undefined on z/OS® because distribution lists are not supported.
