point taken and agreed upon.
My programs in question needs root permissions to 1) apply for real time
scheduling, and 2) programming of /dev/rtc. As these things are done
once at startup time only, I will give up root rights hereafter (setuid
or seteuid, cant remember, not on a Linux system now). I havent tried
this yet, though.
Thanks to all for replying,
