Use getutent(3) on {/etc,/usr/adm}/wtmp to find the LAST run-level
entry.  Sorry, I don't have any System V man pages with me, or I'd try
to hack up a simple loop for you.  Getutent(3) and utmp(5) should have
enough info to get you started.

My opinions, your screen.                                   is much better than
Raxco had nothing to do with this!                        the best day at work.
