pfind(9)

NAME

pfind, zpfind - locate a process by number

SYNOPSIS

#include <sys/param.h>
#include <sys/proc.h>
struct proc *
pfind(pidt_pid);
struct proc *
zpfind(pidt_pid);

DESCRIPTION

pfind() takes a pid as its argument and returns a pointer to

the proc
structure whose PID is specified in the argument only if the

pid is on
the allproc list.

zpfind() takes a pid as its argument. If zpfind() finds a

process whose
PID is equal to that of argument and is a zombie process,

meaning that it
must reside on the zombproc list, zpfind() returns a pointer

to that proc
structure.

Both pfind() and zpfind() lock the proc structure that is

returned using
PROC_LOCK(p).

RETURN VALUES

pfind() and zpfind() return a pointer to a proc structure on

success and
a NULL on failure.
