VM_MAP_DELETE(9)

💖 VM_MAP_DELETE — kernel dev girlies, this one's for you 💖

okay so bestie, welcome to section 9 of the Kernel Developer's Manual 🌸 this is the page for vm_map_delete, and it's giving extremely internal, do not touch unless you know what you're doing energy. no cap. let's get into it 🫶

✨ NAME ✨

vm_map_delete — deallocate an address range from a map 🗺️💅

🦋 SYNOPSIS 🦋

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

int
vm_map_delete(vm_map_t map, vm_offset_t start, vm_offset_t end);

like, three headers, one function, zero drama. she's lowkey elegant 😌

🌈 DESCRIPTION 🌈

so vm_map_delete() deallocates the address range that's bounded by start and end, straight out of the map. that's it. that's the whole vibe. it takes that chunk of address space and it's gone 💀✨

🔥 IMPLEMENTATION NOTES 🔥

listen. this function is for FreeBSD VM internal use only. i'm so serious.

if you're a FreeBSD VM consumer (hey bestie 👋), the one you actually want is vm_map_remove(9). that's the main character. vm_map_delete() is backstage. do not put her on the red carpet 🙈

⭐ RETURN VALUES ⭐

vm_map_delete() always returns KERN_SUCCESS. always. every single time. no surprises, no plot twists, she ate and left no crumbs 👑
