This example:
https://github.com/alanxz/rabbitmq-c/blob/master/examples/amqp_producer.c

uses a direct exchange that will deliver a message to multiple queues if multiple
queues were bound with the same routing key (queue names do not matter).

This tutorial:
http://www.rabbitmq.com/tutorials/tutorial-two-python.html

uses the default exchange which all queues are bound to automatically
with routing key = queue name. because 2 queues cannot have the same name,
we cannot get into the situation above.

So make sure the example you use is equivalent to tutorial 2: uses basic.qos = 1 and default
exchange. Or bind queues to amq.direct with different routing keys (but it is
a needless complication for what tutorial 2 covers).

See http://www.rabbitmq.com/tutorials/amqp-concepts.html if something isn't clear.
