[openamq-dev] Help on Openamq required

[Martin Sustrik]

Hi Mousami,

You cannot expect that amq_client_session_basic_arrived will return 
content every time. If there are no messages received, it will simply 
return NULL. If you want to wait while a message is delivered, use 
amq_client_session_wait. However, if you use amq_client_session_wait 
with a finite timeout (like you do), amq_client_session_basic_arrived 
may still return NULL after the waiting ended (in case the timeout was 
reached).

Following pseudo-code shows how standard message-receiving loop looks like:

while (1) {
     content = amq_client_session_basic_arrived (session);
     if (content) {
         ... process the content ...
     }
     else
         amq_client_session_wait (session, -1);
}
