For what its worth, I've written a version of w(1) using pstat(2) that worked as well as the original except it wasn't setuid-root. I'm sure the same could be done for ps(1) on HP-UX and there is a top-style tool called "yamm" for HP-UX that doesn't need to be setuid root. I also believe that some of the vmstat/systat type tools also use this interface. I think pstat(2) is an excellent idea, so long as you don't believe that the information needed by ps/w, etc, doesn't need to be private. Darren
