Hi,
Sorry, this is really not a linux question, rather a network programming
question if you could still help me out:
1. I have a server / client program of tcp connection on linux. The
server uses a select function to wait clients packets. It works fine
until a client program is terminated. Then the server is crashed (server
program can no longer be blocked at select). How can the server detects
the client terminate without crashing?
2. Is there any system function call or utilities on linux to check
Ethernet and network status?
3. Why we need to cast struct sockaddr_in serverAddress, clientAddress
to struct sockaddr *) in bind(fd, (struct sockaddr *)&serverAddress,
sizeof(serverAddress)) and accept(fd, (struct sockaddr *)&clientAddress,
&clientLength)?
Thank you for your time and patience.
Jim
