[zeromq-dev] zmq_poll() error

[Lindley French]

I'm trying to use zmq_poll() to test whether a TCP dealer or an inproc pull
socket have anything available to read. However, sometimes I am getting an
EINTR error. This appears to be because the poll() function is returning
-1. However, no bits are set in revents for either descriptor, so I'm not
sure what's going on.

Any suggestions?
