35.Fn pfind "pid_t pid"
36.Ft "struct proc *"
37.Fn zpfind "pid_t pid"
38.Sh DESCRIPTION
39.Fn pfind
40takes a
41.Fa pid
42as its argument and returns a pointer to the

53as its argument.
54If
55.Fn zpfind
56finds a process whose PID is equal to that of argument

59list,
60.Fn zpfind
61returns a pointer to that
62.Vt proc
63structure.
64.Pp
65Both
