How can I use C++ client API for request-response message
I want to use C++ client API for request-response message. There is an
example in qpidc-6.0 but it uses a message listener for the response
message. What I want is looking for an API to block the current thread and
waiting for the response message. Does C++ client code support such API?

No, not directly. You can use a UUID to create your own however, or
since the session name is guaranteed to be unique use that as a basis.

One more question. How can I give LocalQueue a uniq name? In above code, the
LocalQueue name will be the session ID name. Does QPID client support
generate a unique queue name?
thanks,

Your code works very well. Thanks very much for your help.

WIth that API (and with 0.6 that is the recommended option), you could
as Steve suggested use LocalQueue instead of MessageListener. See the
attached simple example of the request-response pattern for how that
might look.

No, there is no way to convert between them. It is really an either/or
decision. I would only recommend using the messaging API if you can
update to trunk or wait until the next release (end of October) however.
The 0.6 release did not have a fully implemented messaging API. If you
do want to consider moving to that API at some point, have a read of
http://qpid.apache.org/books/0.7/Programming-In-Apache-Qpid/html/
(refers to trunk code). There is also a client-server example available
for that.

I am using the qpid client API in my program. Do you have any method to
convert the qpid client API to qpid message API? What I have in my program
context is qpid:client:Session and if I use qpid messaging I have to use
qpid:messaging:Session. Is there a way to convert qpid:client:Session to
qpid:messaging:Session?

You could use the qpid::client::LocalQueue, but I would recommend
instead using the qpid::messaging::Receiver class - you can block
waiting for a message.
