DESCRIPTION
 The 
proc_find() and 
pgrp_find() functions retrieve process and process group structures from process ID 
pid and process group ID 
pgid. Both functions must be called by holding a 
mutex(9) on 
proc_lock.

 Upon successful completion, the described functions return a pointer to either struct proc or struct pgrp. Otherwise, if the requested ID was not found, NULL is returned.
