-To stop this daemon:
-
-ll_daemon_stop (lockfilename, pidfile)
-
-
-ll_daemon_start attempts to start a daemon process going.  It does only
-a partial setup.  If it detects that the daemon process is already
-running, it itself does an exit(0), not returning to the parent.
-
-If there was a failure starting a daemon process, -1 is return, else
-we return a transparent file descriptor, which will have to be passed as
-the secodn argument to ll_daemon_started().
-
-When ll_daemon_start returns, we're already running in a partially set-up
-daemon process.  The setup isn't complete just yet.  The parent function
-can perform any other custom initialization.  If initialization fails,
-the parent function can simply exit.  Otherwise, if the initialization
-completes, ll_daemon_started must be called in order to save this daemon
-process's pid in the pid file (2nd arg must be the return from ll_daemon_start.
-
-To stop a daemon process, simply call ll_daemon_stop.  Nothing too
-sophisticated here.
-
-To send the daemon process a SIGHUP, call ll_daemon_restart.
