process question

[Jochen Manns]

Dear UNIX-Experts,

	perhaps it's a FAQ but anyway: how can I get informations on a 
	process which is NOT a child of the process requesting the information:
	a) existence (ok, kill(pid,0) will do the job)
	b) parent pid
	c) user id
	d) perhaps command line
	Is there any standard way to do this (System V.4?). We are using a 
	DG AViiON 300 with System V.3 compatibility and there I found a 
	routine to do this but its name starts with 'dg_' so I think its
	only local to DG/UX.
	
Thank you in advance
