How Do You Determine The PID of the Parent of a Process *

Question

I have a process in erlang that is supposed to do something immediately after spawn, then send the result back to the parent when it is finished. How do I figure out the PID of the process that spawned it?

Answer

You should pass self() to the child as one of the arguments to the entry function.

spawn_link(?MODULE, child, [self()]).
