Dear zmq experts,

I would like to connect my ZeroMQ application with a non-zeromq one via a ZMQ_STREAM socket type.

I basically just need to send out messages to the non-zeromq socket. Is it possible to test if the socket is writable and a send would not block via the usage of poll (with POLLOUT)?

I tested it in a small example and it seems the poll call (with POLLOUT) always returns "yes" although a subsequent call to actually send the message blocks. Is this intended behavior?

Thank you,
Nils
