Using UNIX Domain Datagram Sockets Closing a Socket Closing a Socket In most applications, you do not have to close the sockets. When you exit your program and your process terminates, the sockets are closed for you. If you need to close a socket while your program is still running, use the close system call. You may have more than one process with the same socket descriptor if the process with the socket descriptor executes a fork. close decrements the file descriptor count and the calling process can no longer use that file descriptor. When the last close is executed on a socket, any unsent messages are sent and the socket is closed. Any unreceived data are lost. Chapter 7 159

Using UNIX Domain Datagram Sockets
Closing a Socket
Closing a Socket
In most applications, you do not have to close the sockets. When you exit
your program and your process terminates, the sockets are closed for
you.
If you need to close a socket while your program is still running, use the
close
system call.
You may have more than one process with the same socket descriptor if
the process with the socket descriptor executes a
fork
.
close
decrements the file descriptor count and the calling process can no longer
use that file descriptor. When the last
close
is executed on a socket, any
unsent messages are sent and the socket is closed. Any unreceived data
are lost.
