exflame(3)

💖 exflame — bestie edition 💖

okay so real talk, this is a page from the Allegro manual (the game programming library, you know the one 🎀) and it's filed under section 3, exflame(3). it's an example program, not a function, so don't @ me looking for a signature. sit down, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

exflame — the whole entire how-to on writing directly to video memory so your performance goes from meh to slay. it lives in the Allegro game programming library. 💅

🌈 SYNOPSIS 🌈

#include <allegro.h>

Example exflame

that's it bestie, it's an example, you don't call it, you study it. 👑

🔥 DESCRIPTION 🔥

so this program is literally a demo of how to write directly to video memory. it implements a simple fire effect — yes, actual flames, main character energy — and it does it three different ways so you can watch the glow-up happen in real time:

1. first it does the thing the easy way, by calling getpixel() and putpixel(). cute, works, kinda slow, we love her anyway. 🫶
2. then it levels up and accesses video memory directly, a byte at a time. not me getting my hands dirty fr fr. 💀
3. and finally it pulls out the big guns and uses block memory copy operations. iconic. ate. periodt. 🔥

that's the entire flex: same fire, three levels of efficiency, and now you know how to do all three. no cap. ✨

🎀 tiny note bestie: this is a manual page for exflame in section 3, and it's a page about an example program, so there's no options list and no exit status here. that's not me being lazy, that's just the whole page. don't come for me. 😭

and that's the whole thing!! this page came to you from the Allegro manual, version 4.4.3, and it's signed off as exflame(3). 🦋 thanks for reading, ily, go make some fire (literally). 💜🌸✨
