✨ al_unlock_bitmap ✨

okay bestie, so this one lives in the allegro5 manual (section 3alleg5, for the record) and it's the little sister function to al_lock_bitmap 💖 it's short, it's sweet, it's giving "closing the door behind you" energy. let's get into it 🎀

🌸 NAME 🌸

al_unlock_bitmap — Allegro 5 API 👑

---

🦋 SYNOPSIS 🦋

#include <allegro5/allegro.h>

void al_unlock_bitmap(ALLEGRO_BITMAP *bitmap)

---

💅 DESCRIPTION 💅

So basically: you know how you locked a bitmap (or a region of a bitmap) earlier? yeah. This is how you unlock it. That's the whole vibe. 🔓✨

And here's the part that actually matters, no cap: if the bitmap you're unlocking is a video bitmap, then the texture gets updated to match the system memory copy. Slay. Your changes actually make it to the GPU, bestie 🫶

one tiny caveat though 👀 that texture update happens unless it was locked read only. If you locked it read only, there's nothing to sync back, iykyk. So don't be surprised when nothing moves 💀
