admittedly, I struggle a bit with following your email. To clarify, with
"parent process" you refer to a program that you created, or are you
referring to an instance of init?
If the former is the case (what I'm expecting), how do you run the child
processes? Are you using the Genode::Child class (from 'base/child.h')
or the Genode::Slave class (from 'os/slave.h')?
>From where does the parent receives messages? From any of its children
or some other process?
Just to allow me to get a better grasp on your problem, could you
outline the scenario in slightly more general terms?
