In rabbitmq-c this manifests itself in different ways depending on the function being called: for functions returning an int, a non-zero value is returned, for functions returning an amqp_rpc_reply_t, type will be set to AMQP_RESPONSE_LIBRARY_EXCEPTION and library_error will be set to something non-zero, and for things returning a amqp_*_t object if a NULL value is returned, calling amqp_get_last_rpc_reply() will get an amqp_rpc_reply_t which the above rule should be followed.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>HTH<o:p></o:p></p></div><div><p class=MsoNormal>-Alan<o:p></o:p></p></div></div><div><p class=MsoNormal style='margin-bottom:12.0pt'><o:p> </o:p></p><div><p class=MsoNormal>On Fri, Oct 4, 2013 at 6:13 AM, Jain, Punit <<a href="mailto:Punit.Jain@emc.com" target="_blank">Punit.Jain@emc.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Hi,<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I am using rabbitmq-c amqp client (0.2.0) to publish messages to RabbitMQ broker.
