The RabbitMQ C client was written by Tony. He's currently on leave but
should be able to help out again soon. None of the rest of us have ever
looked at the C client and it is marked highly experimental.

We were hoping some of the other users of the C client might be able to
help out with this one. Digging around the Java client though reveals
the following pattern.
The server will send a Start, the client replies with a StartOK which
contains the username and password. Upon sending that, you should get
back a connection tune method back from the server, if all is well.
Now, if the user details are wrong, the server will shut the connection.
So I guess, unless there's something smarted going on in the C client,
simply checking that the connection is still open might work, but in
general, if you get as far as receiving the connection.tune method, you
can trust that the authentication details you provided have been
I hope that's of some help.
