  Hi,
   I have just begun trying to fool around with ULTRIX structures, and am
getting nowhere. I want to use the user data structure 'u'. (I want to
find the parents pid by using u.u_procp->p_ppid, from an ordinary program).
I think I have included all the required files. Is there any library that
I have to link my program with? Or, as I hope not, can all this be got only
from kernel code (device drivers?) ?

   On a related note, can anybody guide me to a book written on using
lower level unix structures? Well, I know that this posting must have
gone to one of those unix groups, but I normally read only comp.unix.ultrix,
and hopefully there are a lot of ULTRIX people who are UNIX gurus.

   Thanking you in adv.,
