Subject RE: How to receive specific response
Date Mon, 12 Mar 2012 14:59:29 GMT
Hi Todd,

I suggest finding a way to filter the messages into queues private to each
receiver so you don't need to fetch, examine, release each one.

That said, you can qpid::messaging::session::release() a message if you
don't want it - the broker will redeliver it. I'm not completely sure if
it may redelivered to the same client, but it's worth a try.

To keep the message, acknowledge it.
