VM_PAGE_LOOKUP(9)

💖 VM_PAGE_LOOKUP 💖

okay bestie, so this is a page from the Kernel Developer's Manual — section 9, the kernel-nerd corner of the man pages — and it's all about vm_page_lookup. iykyk 🦋

✨ NAME ✨

vm_page_lookup — lookup a vm page 🔍

🌸 SYNOPSIS 🌸

like, here's the whole vibe, verbatim, no cap:

#include <sys/param.h>
#include <vm/vm.h>
#include <vm/vm_page.h>

vm_page_t
vm_page_lookup(vm_object_t object, vm_pindex_t pindex);

🎀 DESCRIPTION 🎀

so vm_page_lookup() goes hunting for a VM page, and you tell it which one you want by handing it a VM object plus an index. that's the whole quest 🧚

if the page isn't found? you get NULL back. that's it, that's the deal, no page for you 🙈

its arguments are, like, literally just these two:

• object — the VM object you wanna search on. this is the thing you're digging through 💅
• pindex — the page index you're searching on. this is the little address-y coordinate inside it ✨

🌈 RETURN VALUES 🌈

if it works out, you get a vm_page_t back — slay 👑

if it does not work out, you get NULL. not found, not your page, move along 🫶
