Question

I try to spawn new process and register it:

-module(db).

-export([start/0]).

start() ->
    register( db , spawn( db, abs, [-100])).

But when i try in erlang shell:

1> db:start().

I see:

true
(emacs@myhost)2>
=ERROR REPORT==== 1-Dec-2010::17:42:27 ===
Error in process <0.112.0> on node ’emacs@myhost’ with exit value: {undef,[{db,abs,[-100]}]}

What’s wrong?

Thank you.

Answer 1

This fails because db:abs/1 is not defined.
