Unblock recvfrom when socket is closed

Viewed 13906

Let's say I start a thread to receive on a port. The socket call will block on recvfrom. Then, somehow in another thread, I close the socket.

On Windows, this will unblock recvfrom and my thread execution will terminate.

On Linux, this does not unblock recvfrom, and as a result, my thread is sitting doing nothing forever, and the thread execution does not terminate.

Can anyone help me with what's happening on Linux? When the socket is closed, I want recvfrom to unblock

I keep reading about using select(), but I don't know how to use it for my specific case.
