Title: nonblocking sockets
Post by: Soul on May 31, 2014, 04:45:38 pm

Hey, i should use nonblocking sockets in my game to make her real-time, and my question, can i use selectors to make server multiclient? or better way is multithread with nonblocking sockets?

FAQ - Should I use blocking or non-blocking sockets? And how do selectors work? (https://github.com/SFML/SFML/wiki/FAQ#network-blocking-non-blocking-selectors)

Sockets are set to block by default and have the function setBlocking() which allows you to toggle blocking.

sf::Socket socket;
socket.setBlocking(false);

Now instead of the socket waiting for when the action can and is performed, it will just return immediately thus preventing your thread from being halted. Check the detailed description of sf::Socket (http://"http://www.sfml-dev.org/documentation/2.1/classsf_1_1Socket.php") for a better explanation of blocking to non-blocking.
