       How do I fork a daemon process?

               If by daemon process you mean one that's detached
               (disassociated from its tty), then the following
               process is reported to work on most Unixish sys-
               tems.  Non-Unix users should check their
               Your_OS::Process module for other solutions.

               o   Open /dev/tty and use the TIOCNOTTY ioctl on
                   it.  See tty(4) for details.  Or better yet,
                   you can just use the POSIX::setsid() function,
                   so you don't have to worry about process
                   groups.

               o   Change directory to /

               o   Reopen STDIN, STDOUT, and STDERR so they're
                   not connected to the old tty.

               o   Background yourself like this:

                       fork && exit;

               The Proc::Daemon module, available from CPAN, pro-
               vides a function to perform these actions for you.
