al_have_opengl_extension(3alleg5)

✨ NAME ✨

al_have_opengl_extension — the Allegro 5 API bestie that checks if an OpenGL extension is even available 💅

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro_opengl.h>

bool al_have_opengl_extension(const char *extension)

---

🦋 DESCRIPTION 🦋

Okay so listen 🫶 — this function is your little helper, your ride-or-die, your vibe check for OpenGL extensions. It figures out whether a given OpenGL extension is available on the given display or not. That's it. That's the whole job. Iconic, honestly.

Like, here's the moment:

bool packedpixels = al_have_opengl_extension("GL_EXT_packed_pixels");

So if packedpixels comes back true, then bestie you are so safe to use the constants related to the packed pixels extension. Go off 👑

It returns true if the extension is available, and false otherwise. Periodt.

No cap: it's literally just a yes-or-no situation. true = available, false = not available, and you should not be out here using extension constants when it said false, okay?? 😭

alright that's the whole page, mwah 💖
