Change vars in the parent process

[Markus Franz]

Hi!


Is there any possibility to change vars inside a parent process from
the inside of a child process?
Thanks

Hi,

No, that's impossible. At least on unix.

Not without adopting some specific inter-process mechanism such as a
network socket. The idea is that processes are *intended* to provide
protection boundaries around separate activities.

Maybe what you need is threads, which can easily access each other's
resources. They do need careful control, though, precisely because they
share a single process's address space and protection boundary.
