How to set the keep alive interval for winsock

Question

I am using winsock and TCP. I have set the KeepAlive option as follows

int aliveToggle = 1;
setsockopt(mySocket,SOL_SOCKET,SO_KEEPALIVE,(char*)&         


        

Answer 1

From c/c++ you should be able to use SIO_KEEPALIVE_VALS to control the timeouts. You can't use setsockopt, but you should be able to use WSAIoctl. See http://msdn.microsoft.com/en-us/library/windows/desktop/dd877220%28v=vs.85%29.aspx
