Hello,

I've programmed client-server type applications using sockets before,
but on Windows.

I understand that to allocate a socket, I must call 'socket'

What I do not understand is how to discard the socket: is there a
diffierent way on *nix (or embedded)?

Usually, I would call 'closesocket' (on Windows) or 'close' on *nix but
the sys/socket.h file doesn't define a close function, so which close do
I call?

you can call close included unistd.h on the fd(socket)

or shutdown from sys/socket.h

Uhm. shutdown() does not release the file/socket descriptor and you
still need to call close(). Simpler just to call close() in the
first place.
