Description
Tools for writing daemons/server processes Written by John Goerzen, jgoerzen@complete.org Please note: Most of this module is not compatible with Hugs. Messages from this module are logged under `System.Daemon`. See System.Log.Logger for details. Based on background from http://www.erlenstar.demon.co.uk/unix/faq_2.html#SEC16 and http://www.haskell.org/hawiki/HaskellUnixDaemon. This module is not available on Windows.
Synopsis
detachDaemon :: IO ()
Documentation
detachDaemon :: IO () | Source
Detach the process from a controlling terminal and run it in the background, handling it with standard Unix deamon semantics. After running this, please note the following side-effects: The PID of the running process will change stdin, stdout, and stderr will not work (they'll be set to /dev/null) CWD will be changed to / I highly suggest running this function before starting any threads. Note that this is not intended for a daemon invoked from inetd(1).
