Hi everybody,
I am using the fnet-stack.
I create a socket with socket(), bind() and accept().
The Client connects, I use the socket that is returned by accept()
and we both can send and receive.
When the Client disconnects, I see a FIN / FIN ACK / ACK sequence in Wireshark,
but how does my application know that the connection is closed (or timed out)?
The socket Status returned by getsockopt() is still 2 = SS_CONNECTED,
calls to subsequent sendto() do not yield an error
and the Information is sent as if the connection were still open.
So, how do I detect when the client has disconnected a TCP-connection?
Greetings, Martin
