-***************
-Run as a daemon
-***************
-
-CherryPy allows you to easily decouple the current process from the parent
-environment, using the traditional double-fork::
-
- from cherrypy.process.plugins import Daemonizer
- d = Daemonizer(cherrypy.engine)
- d.subscribe()
-
-.. note::
-
- This :ref:`Engine Plugin<plugins>` is only available on
- Unix and similar systems which provide fork().
-
-If a startup error occurs in the forked children, the return code from the
-parent process will still be 0. Errors in the initial daemonizing process still
-return proper exit codes, but errors after the fork won't. Therefore, if you use
-this plugin to daemonize, don't use the return code as an accurate indicator of
-whether the process fully started. In fact, that return code only indicates if
-the process successfully finished the first fork.
-
-The plugin takes optional arguments to redirect standard streams: ``stdin``,
-``stdout``, and ``stderr``. By default, these are all redirected to
-:file:`/dev/null`, but you're free to send them to log files or elsewhere.
-
-.. warning::
-
- You should be careful to not start any threads before this plugin runs.
- The plugin will warn if you do so, because "...the effects of calling functions
- that require certain resources between the call to fork() and the call to an
- exec function are undefined". (`ref <http://www.opengroup.org/onlinepubs/000095399/functions/fork.html>`_).
- It is for this reason that the Server plugin runs at priority 75 (it starts
- worker threads), which is later than the default priority of 65 for the
- Daemonizer.
