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).
