The 'w' command prints out the time each logged-in user has been idle. How do I get at that infomation myself, without grep'ing etc the output ? The /etc/utmp file dosen't store this information, so it must come from somewhere else (kmem ?). Any pointer gratefully received.

The way finger does it is to get the user's tty from /etc/utmp and then do a stat on /dev/userstty. The st_atime member of the stat struct obtained, being the last access time, will allow you to determine the idle time. I hope this helps.
