How do I know if a connection is still connectd?

Hello,
Is there any way in C++ to find if a tcp connection is still connected or lost connection.

I'm trying to do something like this:

if(is still connected)
{
//code...
}

Thanks,
Alaa

In general you don't.

You may not always get a "notification" when a connection fails.

If the connection has been lost, then when you try and use it, it will fail.
That is how you know.
