[erlang-questions] Sending messages to multiple processes?
Fri May 1 03:37:37 CEST 2009
Is there a neato idiom for sending a single message to multiple
> processes, up to say 200, or do I just need to loop it?
No "idiom" that I'm aware of.
You can use the pg module to group a bunch of processes together and
send them messages via the group name. Info:
I also need to know they finished processing the message. Is this the

That's just a matter of sending the "master process" Pid to the
workers/slaves when they are started and having then report back when

For this simple case you can stick to your own master/slave processes. :)
