How to make the recv function in winsock2 stop after a specific time..?

Question

In an developing a Windows Desktop Console Application in c++ in Visual Studio 3013 for Windows Desktop, which acts as a client and tries to connect to a server. Once the Connection with the server is successful, it sends a handshaking signal to the
server and waits for a response from the server. Iam using winsocks2 in this application. The receive function I am using is a blocking call
iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0);
So until my server sends a response, the client is blocked. What I need is the client to check for response only for a certain time (say 10 sec). If there is no response within this time frame ,I want the client to disconnect from the server. How to achieve
this?

You could use setsockopt

to set the timeout option, SO_RCVTIMEO, for the recv
function.
