Hi,
what is the semantics of zmq_poll when the remote side of the socket is closed?
My sample program
int main()
{
zmq::context_t ctx;
zmq::socket_t s1{ctx, ZMQ_PAIR};
zmq::socket_t s2{ctx, ZMQ_PAIR};
s1.bind("inproc://1");
s2.connect("inproc://1");
auto t = std::thread( [&]() {
std::this_thread::sleep_for( std::chrono::seconds(5) );
s1.close();
});
zmq::pollitem_t pollitems[] = { {static_cast<void*>(s2), -1, ZMQ_POLLIN +
ZMQ_POLLERR + ZMQ_POLLOUT, 0} };
auto rc = zmq::poll(pollitems, 1);
std::cout << rc << std::endl;
std::cout << pollitems[0].revents;
t.join();
return 0;
}
prints 2 which is ZMQ_POLLOUT. However, I cannot see this in the documentation.
Best wishes,
Jens
