Prompt for root password

[JD Arnold]

I'm writing a program that needs to write a file and I'd like to have it
ask for the root password and run as root, like many of the system config
applications do.  Do I have to write something special, or is there some
way to tell KDE (or GNOME) to prompt for the root password? Is this what
a "setuid" program is?

UNIX is user-friendly. It's just a bit picky about who its friends are.
