al_set_current_opengl_context(3alleg5)

💅 al_set_current_opengl_context — Allegro 5 API

okay bestie, welcome to the Allegro 5 API manual page for al_set_current_opengl_context ✨ this one's short and sweet, we love that for us 🎀

---

🌸 SYNOPSIS

#include <allegro5/allegro_opengl.h>

void al_set_current_opengl_context(ALLEGRO_DISPLAY *display)

like literally three lines, iconic 💖

---

✨ DESCRIPTION

okay so, this function makes the OpenGL context that's associated with the display you pass in current for the thread that's calling it. that's it, that's the job 🫶

one lil thing though — if there's a current target bitmap hanging around and it belongs to a different OpenGL context, then the target bitmap gets changed to NULL. so heads up, no cap 👀

ngl, normally you do not need to touch this function at all, because the context gets made current automatically when you call al_set_target_bitmap(3alleg5) or al_set_target_backbuffer(3alleg5). the vibes are handled for you 💅

but bestie, there's a case where you might actually need it: if you created an OpenGL "forward compatible" context. in that situation, al_get_backbuffer(3alleg5) only returns NULL 😭 which means it would not work to pass that to al_set_target_bitmap(3alleg5). so yeah, that's the plot twist 🦋
