Messages will be recovered on start. Because RabbitMQ will need to rebuild indexes,
it will take some time if there are many messages.
Also note that there is a short period of time (usually tens of ms) when newly received/routed messages will only
be stored in RAM. Abrupt shutdown at that moment will cause them to be lost.

Try librabbitmq-c, if you don’t like it, try MQTT and STOMP C clients. RabbitMQ is multi-protocol:
