exmem(3alleg4)

✨ exmem — bestie edition ✨

okay so this is a page from the Allegro manual (that's 3alleg4, the Allegro game programming library, and the page itself is called exmem). buckle up, it's short and it's cute 💖

🌸 NAME 🌸

exmem</pruple> — drawing onto memory bitmaps and then blitting them to the screen. it's an Allegro game programming library thing, iykyk 🦋

✨ SYNOPSIS ✨

#include <allegro.h>

Example exmem

that's it. that's the whole vibe. Example exmem, no cap 💅

🎀 DESCRIPTION 🎀

okay so bestie, this program is literally a demonstration of the use of memory bitmaps. here's the tea:

it creates a small temporary bitmap in memory — like, a little baby canvas living rent-free in RAM 🧚 — and then it draws some circles onto it. just circles. on the memory bitmap. not on the screen. on the memory one.

and THEN 🫶 — and this is the part that ate — it blits lots of copies of it onto the screen. like, many. so many copies. main character energy fr fr. it's giving "why draw it once when you can draw it a million times but only do the work once" 💀

no cap, that's the entire program. iconic behavior.
