I need a non-blocking socket tutorial.
Author
Does anyone know where I can find a non-blocking socket tutorial? I have looked around and I can only find blocking and asychronous. I have to use non-blocking because my program is a console app, so asychronous won''t work with it.
You could try to look at the "select" function. Or use multithreading (that''s what I did at first, but I''m trying to figure out how to implement select in my program).

select is async...and multithreading might be an unessesary step. Check out fcntl(). And also, there is no reason at all why you cant use async in a console app. While windows apps use WSAAsyncSelect(), a console app can implement the BSD select() call just like in a *nix app.
Here''s a function you can use to toggle a SOCKET between blocking and non-blocking mode.
// CHRIS
//// Set Socket Blocking Mode// sock = SOCKET Handle// mode = 0 for BLOCKING, 1 for NON-BLOCKING//BOOL SetSocketBlockingMode(SOCKET sock, int mode){ unsigned long lmode = mode; if(ioctlsocket(sock, FIONBIO, &lmode) == SOCKET_ERROR) return(FALSE); return(TRUE);} // CHRIS
