Module `Stdune.Daemonize`

Start, stop and synchronize with a daemon

The daemonize function will fork a daemon running the given function, guaranteeing that at most one instance will run at any given time. The daemon has to call a given callback to indicate that it has successfully started, unlocking all other potential start attempts. This callback can be given daemon_info that can be retrieved by the starting process and other start attempts, e.g. the endpoint to contact the daemon on.

type status =

| Started of {
1. daemon_info : string;
2. pid : Pid.t;
}
(*
The daemon was started in the background with the given daemon_info and pid.
*)
| Already_running of {
1. daemon_info : string;
2. pid : Pid.t;
}
(*
The daemon is already running in the background with the given daemon_info and pid.
*)
| Finished
(*
The daemon was run synchronously and exited.
*)
