It's just a theoric question for now :)

- A client open a XREQ socket and connects to a server (REP/XREP).
- It set the water mark to 5.
- It sends 5 requests using non-block. All of them fail (so they are
queued) in the XREQ outgoing queue.
- When it tries to send a new request zqm_send should reply EAGAIN
(the message couldn't be sent neither queued, am I right?).

My question is: how can the client determine that the request couldn't
be sent due to over-full queue in its XREQ socket?

I hope it's clear now :)

Thanks a lot.
