I have a TCP socket Server in Windows PC and have 10 TCP socket Clients (Linux) on 10 PC.
After the Server and the Clients start, the Clients will connect to the Server and
does keep the connections for data transfer.
The Server listen to and create a new work thread for the connected client socket......
I want to know the 10 connections are always on, so the 10 client sockets must periodly
send the bit data to the Server to make sure that it is connected.......
I need to find the more efficient method to do that ? Maybe I can know each connection
is down off immediately ?
