[zeromq-dev] How to detect dead connected client for ROUTER

[Alexander Altshuler]

Hi

>Obsolete ECANTROUTE errror code removed

I have a DEALER client connected to ROUTER server.
Client sends a bulk of messages and exit.
When after some time server try to send first response it is blocked on
first zmq_sendmsg() - while sending client reply address.
zmq_errno() returns EAGAIN if I use ZMQ_DONTWAIT flag.

Is there any way to distinguish between real HWM use case and dead
client?

Regard
Alexander
