sending of messages to several childs

[info-1679]

Hi all,

Is it possible for a "father process" to send the same message to all spawned childs ?
What is the syntax / or reference ?
Thank's

John

maybe you should keep pids of all your children and then iterate over the
list and send same msg?

you can use spawn_link/2 to spawn your children and use erlang:process_info(Father,links) to get all linked process

if the father process is a supervisor you can use supervisor:which_children/1

you can use pg or pg2 module to add all chidren to the same group

Hi John.

There is no built in operator for that, bou could look at:
global_group <http://www.erlang.org/doc/man/global_group.html>
pg2 <http://www.erlang.org/doc/man/pg2.html>
pg <http://www.erlang.org/doc/man/pg.html>

Either way you have to do some book keeping or leg work  to make it happen.

Cheers,
Torben

This solution seems elegant. I will test it.
Thank you
John
