[zeromq-dev] Signal handling in blocking zmq_recv

[Brian Granger]

All,

>> If pthread_sigmask() is used to block any signals from interrupting the I/O thread, how do one unblock a blocked zmq_recv?  What's the alternative if we need to do so?

The blocked zmq_recv seems to be the crux of the problem.

I agree that most of the time, you would be exiting the application.
But, you might want to trigger
clean up actions of various sorts, before exiting.
