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.
