PFIND(9) FreeBSD Kernel Developer's Manual PFIND(9)
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.
