Every time I call connect() on a host that isn't alive it takes like 30 seconds to complete... I want to minimize this time by specifying my own "timeout", so say... I want a timeout of 5 seconds, if connect() cannot find the host in 5 seconds then the function returns. I'm looking on MSDN and all I can see it say is this:
But the only problem is that MSDN doesn't mention HOW to make the socket or connect() nonblocking.Code:With a nonblocking socket, the connection attempt cannot be completed immediately. In this case, connect will return SOCKET_ERROR, and WSAGetLastError will return WSAEWOULDBLOCK. In this case, there are three possible scenarios: * Use the select function to determine the completion of the connection request by checking to see if the socket is writeable.
So I'm just wondering how I can do this, I'm going to be using a function Check_Host() and I'm guessing I'll need a non-blocking connect(), then a call to select() with a timeout specified of 5 seconds or whatever I choose, and if select() errors after that 5 seconds the host is assumed not alive.
Only problem is I have no idea how to do the whole non-blocking thing Thanks.
