Hello,
If somebody want to set a timeout when receiving from a socket, there are
two approaches:
1. setting ZMQ_RCVTIMEO socket options and call zmq_recv() which will set
error EAGAIN, if there's nothing in the queue
and
2. polling the socket with a given timeout?
zmq_pollitem_t items [] = { { socket, 0, ZMQ_POLLIN, 0 } };
int rc = zmq_poll (items, 1, timeout * ZMQ_POLL_MSEC);
which will return 0 if nothing to receive.
In the guide I see that the second method is widely used, however as I
remember I haven't met with the 1st approach. why is this, is it just a
choice, or are there any performance or other differences?
thx
b.
