REMOVE_DISPLAY_SWITCH_CALLBACK(3)

💅 remove_display_switch_callback — the Allegro manual, bestie edition 🎀

okay so this is a page from the Allegro manual (section 3, iykyk — that's the library functions girlies ✨), and it's all about yeeting a callback you don't want anymore. no cap, it's a short one, but it's iconic.

🌸 NAME 🌸

remove_display_switch_callback — removes a switching notification callback. it's giving "Allegro game programming library", and it's giving exactly what it says on the tin, fr fr.

✨ SYNOPSIS ✨

#include <allegro.h>

void remove_display_switch_callback(void (*cb)());

like, that's the whole vibe. one include, one function, one lil function pointer. periodt.

🦋 DESCRIPTION 🦋

okay bestie, listen. this function removes a notification callback — and specifically, the one that was previously installed by calling set_display_switch_callback(). so if you set one up earlier and you're like "actually no, not anymore 💀", this is your girl.

and here's the tea 🍓: all the callbacks will automatically be removed when you call set_display_switch_mode(). so you don't even gotta clean up after yourself in that case — it's handled. main character energy from set_display_switch_mode(), honestly.

and the best part?? you can safely call this function even if the callback you want to remove is not installed. no error, no drama, no crash. it just doesn't care. lowkey the most chill function in the whole library. 🙈

ngl that last bit is the real slay here — no defensive checks needed on your end, just call it and move on with your life 💖
