Programmatically getting list of child processes of a given PID

Question

I'd like to get a list of all the immediate children of a given PID. I'm OK with using /proc but /proc/<PID>/task/<PID>/children is NOT precise and may return inaccurate results (see section 3.7 here). I'd like a more reliable method of doing this.

I'd prefer not using a wrapper around a shell command.

Why not use psutils?

Here is an example where I kill all the children.

def infanticide(pid):
    try:
      parent = psutil.Process(pid)
    except psutil.NoSuchProcess:
      return
    children = parent.children(recursive=True)
    for p in children:
        os.kill(p.pid, signal.SIGKILL)

Is there a nice port for Nodejs? I could find some attempts but nothing complete. – Coder Aug 17 '16 at 20:37
Sorry I fell for the python tag. Not up on my Node.js. – Ian A. Mason Aug 18 '16 at 02:32
