💖 expackf(3) 💖

okay bestie, welcome to the Allegro manual — this is expackf, and it's all about using custom PACKFILE vtables. it's an example program from the Allegro game programming library, and honestly? it's giving tutorial energy and we're obsessed. 🎀

✨ SYNOPSIS ✨

#include <allegro.h>

Example expackf

🌸 DESCRIPTION 🌸

so this program is literally a demo of the packfile functions, and it runs some simple tests to show you how it all works. no cap, it's hands-on from the jump. 🦋

The first test uses the standard packfile functions to transfer a bitmap file into a block of memory, then reads the bitmap out of the block of memory — and it does that using a custom packfile vtable. iconic behaviour tbh. ✨

The second test reads in a bitmap with another custom packfile vtable, which uses libc's file stream functions. different vtable, same slay. 💅

The third test demonstrates seeking with a custom vtable. the way that seeking just works when you set up your vtable right? main character energy fr fr.

The fourth test reads two bitmaps, and dumps them back into a single file, using a custom vtable again. two bitmaps, one file, no drama. 👑

🛠 Tools

(yes bestie, that's the whole subsection — the original just says "Tools" and leaves you to it 🙈)
