[openamq-dev] amq_client_session_basic_consume_nowait() semantics

[Martin Sustrik]

Hi,

The same applies to all functions ending with _nowait:

Normal function (without _nowait) sends request to the broker, then 
client waits for confirmation from broker and exits. The problem is that 
invoking a lot of functions this way is time consuming. Each of them 
requires a network roundtrip.

Thus, _nowait is intended to make the process fast. Request is send to 
broker and function exits immediately without waiting for the response 
from the broker - actually, the response is not even generated by the 
broker.

Hope this helps.
