I don't clearly understand your question, especially if you
read Stevens books, but I'll try to answer.
new_fd variable is just overwritten each time accept() returns a new
socket descriptor for a new connection. If you need to keep connections
with all clients at "the same time" in a single server, so, you need to
save each new_fd descriptor in an array, for example.
If you fork() a new process for handling a new connection, then you need
to close() new_fd descriptor in the server and use new_fd descriptor in
the forked process.
In any way, it is better to ask such questions in comp.unix.programmer
news group.
