[erlang-questions] Stopping a supervisor running under a supervisor

[Chris Clark]

Hi Antonio

Thanks for the assistance. From what I have read  a supervisor should stop
if it is sent a shutdown signal using exit(Pid, shutdown). but it will only
accept that signal from its parent process in an OTP application. I tried
creating a function in the parent supervisor(my_supersup) stop_child(Pid)
that then sends the exit(pid, shutdown) signal and then call that from the
shell but that doesn't seem to stop it either.

Thanks,
