Stopping a socket in blocking mode

[LemonLake]

I have a UDP socket running on a separate thread for the game server. When the host enters the quit command, it needs to stop the socket from the main thread. How do we do this?

SFML provides no way to stop a waiting socket. The best solution is to use a socket selector with a timeout, so that you block only for a certain duration, and can perform periodic termination checks.
