Hey guys,
So, I've integrated ØMQ into my server. Now, I want to use ØMQ as a means to
supply information to a HTTP server from a separate management app. So, in
theory, it will look something like this
int read_zmq_connections() {
int ret = 0;
while (zmq_has_messages(zmq_responder)) {
char *str = s_recv(zmq_responder);
parse_new_data(str);
free(str);
++ret;
}
return ret;
}
This way, if there are no messages on zmq_responder, then the function will
simply return. What I don't know how to do (and can't quite find) is how to
check if messages exist on the connection. Can anyone please point me in the
right direction?
The reason why I need this non-blocking is that I will only be calling
'read_zmq_connections' approximately once every five minutes and I don't want
my app to hang while waiting for messages.
Thanks loads in advance,
Lee
