daemonize-doublefork
Start background Haskell daemons by double-forking
Deprecated
This package has been deprecated in favour of daemons.
What
This module provides startDaemon
and stopDaemon
to facilitate the
creation of Haskell daemon programs.
The problem is as follows: the user starts a program in their
terminal, but he wants the program to relinquish control of the
terminal immediately, and furthermore, the program (or part of it)
should keep running even after said terminal is closed. Examples of
programs that behave like this are nginx
and emacs --daemon
.
The correct solution is to double-fork a process. This ensures that the child process is completed separated from the terminal it was started on.
See this page for a discussion on double-forking.
See the Hackage page for documentation and examples.
