al_get_opengl_fbo(3alleg5)

💅 al_get_opengl_fbo — Allegro 5 API

okay bestie, welcome to al_get_opengl_fbo from the allegro5 manual 💖 this one's a lil OpenGL-adjacent cutie and she's actually pretty chill, let's get into it.

---

✨ SYNOPSIS ✨

#include <allegro5/allegro_opengl.h>

GLuint al_get_opengl_fbo(ALLEGRO_BITMAP *bitmap)

---

🦋 DESCRIPTION 🦋

So basically, this function hands you back the OpenGL FBO id that the given bitmap is using internally — if it's using one. If it's not, you just get zero. That's it, that's the whole vibe.

⚠️ real talk though: it will not try to create an FBO for you if the bitmap isn't owned by the current display. No attempt, none, zero effort, she's not doing that 💀

And here's the important part about ownership — the FBO this function returns only gets freed when the bitmap itself is destroyed, or if you call al_remove_opengl_fbo(3alleg5) on that bitmap. So like, it's not going anywhere until one of those two things happens, fr fr.

📝 Note: back in Allegro 5.0.0, this function would only return an FBO that had already been created by calling al_set_target_bitmap(3alleg5). It would not attempt to create an FBO itself. That has since been changed, bestie — glow up achieved ✨
