g_spawn_async use

[Alexis Sukrieh <alexis sukrieh wanadoo-sp net>]

Hello list :)

I don't know if this is the right place for my question, feel free to 
tell me if there is a better lsit for that topic.

I'm writing a Gtk2 app which has to launch external processes. To do 
that I use the Glib function "g_spawn_async".

My external is well launched but I wonder how I can be notified when it 
is finished. I was thinking about being aware of SIGCHILD but I don't 
know the best way to keep my code Gnome2 compliant.

If someone would tell me what is the best way to do that, it would be great.

Thanks

Alexis.
