Using Internet Datagram Sockets Closing a Socket Closing a Socket In most applications, you do not have to worry about cleaning up your 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 HP-UX file system call close. 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. Then the socket is destroyed and can no longer be used. For syntax and details on close, refer to the close(2) man page. 100 Chapter 4

Using Internet Datagram Sockets
Closing a Socket
Closing a Socket
In most applications,
you do not have to worry about cleaning up your
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
HP-UX file system call
close
.
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. Then the socket is
destroyed and can no longer be used.
For syntax and details on
close
, refer to the
close(2)
man page.
