It depends on the used socket implementation (raw / POSIX sockets, WinSock, CSocket, or CAsyncSocket Class[^]).

With raw sockets, use the select function (Windows)[^] passing the timeout.

With blocking receive calls, you can set the SO_RCVTIMEO socket option (see setsockopt function (Windows)[^]).

When using CAsyncSocket, you have to implement your own timer that is reset when data are received.

With non-blocking calls you usually wait for events with WaitFor(Single|Multiple)Object(s) which have a timeout parameter. I recommend this when using a worker thread for receiving because the call can also catch a terminate event to stop the thread when closing the connection by intention like when terminating the application.

Once a timeout is detected you close the related connections / sockets like when terminating the application. Afterwards enter the listen state again on the server and try to (re-)connect on the client like when starting the applications.

A complete example - even when knowing the used socket type - would be far too much for this forum. But there are a lot of tutorials in the net and here at CP about the topic.
