Fwiw, /bin/ps does this by creating it's own struct which has a 'struct kinfo_proc' as one variable inside of it. However, this means that `ps' has to copy all the kinfo_proc's that the kernel returns into an array of these other structs. Depending on what the program is doing with those kinfo_proc's, this new variable would probably make more sense. > > Are there any guidelines for adjusting this struct that I > > should be aware of? It would be nice to make sure that alignment issues are not wasting space on *any* of the platforms. When I made my recent changes to user.h, I had a program which printed out all the variables and their alignments. If I have time this week I will update that program and see what it says on the different hardware platforms. > > Can anyone do it for me? > > > > thank you! -- Garance Alistair Drosehn = gad_at_gilead.netel.rpi.edu Senior Systems Programmer or gad_at_freebsd.org Rensselaer Polytechnic Institute or drosih_at_rpi.eduReceived on Mon Jul 12 2004 - 03:23:30 UTC
