NAME¶
pfind,
zpfind —
locate a process by number
SYNOPSIS¶
#include
<sys/param.h>
#include
<sys/proc.h>
struct proc *
pfind(
pid_t
pid);
struct proc *
zpfind(
pid_t
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.
