EventMachine::ProcessWatch

Returns the pid that EventMachine::watch_process was originally called with.

    # File lib/em/process_watch.rb, line 21
21:     def pid
22:       @pid
23:     end

Should be redefined with the user’s custom callback that will be fired when the process exits.

stop_watching is called automatically after this callback

    # File lib/em/process_watch.rb, line 34
34:     def process_exited
35:     end

Should be redefined with the user’s custom callback that will be fired when the prcess is forked.

There is currently not an easy way to get the pid of the forked child.

    # File lib/em/process_watch.rb, line 28
28:     def process_forked
29:     end

Discontinue monitoring of the process. This will be called automatically when a process dies. User code may call it as well.

    # File lib/em/process_watch.rb, line 39
39:     def stop_watching
40:       EventMachine::unwatch_pid(@signature)
41:     end
