[rabbitmq-discuss] rabbitmq-c RPC-style commands doesn't work after amqp_get_rpc_reply return AMQP_RESPONSE_SERVER_EXCEPTION

[Alan Antonuk]

Also note that I'm currently working on documenting rabbitmq-c, so
hopefully in the near-ish future there will be some 'best practices' on how
to do all of this.

You can find further details on progress here:
