Hi all,
I'm wondering what is the best approach to polling a non-zmq socket
using czmq. It doesn't seem documented?
I can add a fd as follows:
...
s=socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP)) == -1)
zpoller_add(poller, &s);
...
If I then poll zpoller_wait returns on activity however it's not a valid
zsock_t instance:
zsock_t *which = (zsock_t *)zpoller_wait(poller, -1);
zsock_is(which) will return false. I've found 'which' is just what you
added to the poller so if I cast to an int it will resolve to the
correct filedescriptor number.
So either I cast it back to an int or I keep checking the pointer
addresses. However casting an int to zsock_t doesn't feel safe.
So question is what is best/safest approach?
Rg,
Arnaud
