[openamq-dev] A try version of amq_client_session_wait?

[Pieter Hintjens]

Ryan,

Yes, it would be possible to make a method that did what wait() did,
except the wait part.  That is, wait() is responsible for shoving
arrived and returned messages onto their respective lists.  So we
could add a method that shoves any messages already arrived, but does
not wait for new ones if there are none.

It would be a useful addition, I think.  Please make a change request
on www.openamq.org, so that it does not get lost.
