💖 PFIND(9) — Kernel Developer's Manual 💖

okay bestie, welcome to PFIND(9) ✨ this is the kernel dev manual page for two little functions that go find a process for you, and honestly? they ate. let's get into it 🫶

🌸 NAME 🌸

pfind, zpfind — locate a process by number 🔍

✨ SYNOPSIS ✨

like, here's the whole vibe, copy-paste it exactly bestie:

#include <sys/param.h>
#include <sys/proc.h>

struct proc *
pfind(pid_t pid);

struct proc *
zpfind(pid_t pid);

💅 DESCRIPTION 💅

okay so. pfind() takes a pid as its argument and returns a pointer to the proc structure whose PID is specified in the argument — but ONLY if that pid is on the allproc list. no allproc, no pointer, that's the rule 🎀

and then zpfind() also takes a pid as its argument. if zpfind() finds a process whose PID is equal to that of the argument and it's a zombie process — meaning it must reside on the zombproc list 🧟 — then zpfind() returns a pointer to that proc structure. it's giving "found the undead one" 💀✨

both pfind() and zpfind() lock the proc structure that is returned, using PROC_LOCK(p). 🔒 no cap, that lock is real, respect it.

🌈 RETURN VALUES 🌈

pfind() and zpfind() return a pointer to a proc structure on success 💖 and a NULL on failure 😭 that's it, that's the whole deal.
