al_register_assert_handler(3alleg5)

💖 NAME 💖

al_register_assert_handler — it's part of the Allegro 5 API, bestie, and it's the little hook that lets you decide what happens when Allegro's own internal assertions go off 🫶

---

✨ SYNOPSIS ✨

#include <allegro5/allegro.h>

void al_register_assert_handler(void (*handler)(char const *expr,
   char const *file, int line, char const *func))

---

🌸 DESCRIPTION 🌸

okay so listen 👑 — you're handing Allegro a function pointer here, and that function is gonna get called every single time an internal Allegro assertion fails. That's it, that's the whole vibe. Your handler, your rules, your moment 💅

The signature is very specific and you gotta match it exactly, no cap:

• the first param is char const *expr — the expression that didn't hold up
• then char const *file — where it happened
• then int line — the line number, iconic
• then char const *func — the function it happened in

And if you pass NULL as the handler? That's you saying "nvm bestie, reset me" and it goes right back to the default behaviour, which is to literally just do whatever the standard assert() macro does. Nothing more, nothing less 🦋

heads up: passing NULL doesn't disable anything, it just restores the boring default. The default is the standard assert() behaviour, periodt.
