I'm not sure but skimming your code you are mixing czmq sockets and zmq
poll method. If you want to use the zmp_poll method you can use
zsock_resolve on the czmq sockets
// Probe the supplied reference. If it looks like a zsock_t instance,
return
// the underlying libzmq socket handle; else if it looks like a file
// descriptor, return NULL; else if it looks like a libzmq socket handle,
// return the supplied value. Takes a polymorphic socket reference.
CZMQ_EXPORT void *
zsock_resolve (void *self);
Otherwise use the zpoller czmq class instead of zmq_poll

hi all,
i am using zactor and in the call back i receive a pipe socket.
i create a router socket and polling this sockets for messages.
it is not working and giving -1 result as return value of zmq_poll;
what could be the problem?
