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 Fa pid as its argument and returns a pointer to the Vt proc structure whose PID is specified in the argument only if the Fa pid is on the allproc list.

zpfind ();
takes a Fa 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 Vt proc structure.

Both pfind ();
and zpfind ();
lock the Vt proc structure that is returned using PROC_LOCK (p .);
