RE: [GD-Linux] Cancelling blocking recv calls on Linux

[Hal A. <ha...@cl...>]

I saw EINTR in the man pages - I couldn't figure out which signal to the
thread though.

I would send the signal by doing something like this:
pthread_t threadId_;
pthread_kill( threadId_, SIGKILL );

(Kill actually kills my entire process not just the target thread).

Any ideas on the signal to use?

Have you tried sending a signal to the blocked thread? When you do, recv()
should return -1 and set errno to EINTR. From there the thread can check a
global variable or something that symbolizes that the system is shutting
down, and exit cleanly if it's set.
