hello,
write a signal handler to close the socket, and you'll be fine.
otherwise, the system closes it for you, but it takes a bit.
Thanks,

Subject: [c-prog] sockets - bind() error, address already in use
I've got a client and server program communicating over a stream
socket. They are C programs compiled using gcc running under Linux.
The server calls socket(), bind(), listen(), then loops round calling
accept() and creating a thread to read() messages on the connection.
The thread exits when the read() returns 0 (indicating EOF on the socket).
The client calls socket() and connect() to connect to the server, then
write() to send messages to it.
This all works fine, until I stop the programs using CTRL-C. Then when
I re-run the server I sometimes get a 'address already in use'
returned by bind(). However, if I wait a minute or 2, it's ok again.
I guess it's because I'm not closing down the socket properly or
something. I'm no socket expert - what am I missing out?
Cheers
John
