Thanks, David and Shlomi (and those that read),
I understand fork() and the style of writing better. Strange that the
defaults for 'use English' are not optimal.
The snippet below works to fork as a specific user, if run as root.
However, it generates zombies. The functions wait() or waitpid()

Hello all.
AFAIK, you can't do that. When you fork everything is copied, including
the UID.
To achieve something similar, you need to launch another process (but
you'll need to be root to launch it as another user)

If I have the code below to fork a child process, how would the right
way be to fork as a different user? I gather that fork() itself does
not support that, so some other method must be used.

Lars
