SDL_HINT_ASSERT(3)

✨ SDL_HINT_ASSERT(3) ✨

okay bestie, welcome to the SDL_HINT_ASSERT page from the SDL3 functions manual 💖 this is the lil hint that decides what happens when an SDL_assert goes off, and ngl it's lowkey iconic because you get to pick the whole vibe of the aftermath 🎀

---

🌸 NAME 🌸

SDL_HINT_ASSERT — a variable that controls how SDL reacts when an SDL_assert fails 💅

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_hints.h>

#define SDL_HINT_ASSERT "SDL_ASSERT"

---

✨ DESCRIPTION ✨

So like, you can set this variable to one of these values, and yes they are case-sensitive, so don't get cute with the capitalization, bestie 🙈

• "abort" — the program terminates immediately. like, right now. no notes. 💀
• "break" — the program triggers a debugger breakpoint. main character move for debugging 🐛✨
• "retry" — the program reruns the SDL_assert's test again. run it back 🔁
• "ignore" — the program continues on and ignores this assertion failure this time 🙈
• "always_ignore" — the program continues on and ignores this assertion failure for the rest of the run. commitment fr fr 💅

just so u know: SDL_SetAssertionHandler is the programmatic way to deal with assertion failures, through a callback 🫶 and this hint is largely intended to be used via environment variables by end users and automated tools. iykyk 🌈

This hint should be set before an assertion failure is triggered, and it can be changed at any time 👑 (so yes, you can switch up the vibe mid-run, slay).

---

💜 AVAILABILITY 💜

This hint has been available since SDL 3.2.0 ⭐

and that's the whole page, periodt 🎀 written by the fine folks behind Simple Directmedia Layer, from the SDL 3.4.18 era, dated all the way back to the SDL_HINT_ASSERT(3) days 🦋 mwah, go forth and assert responsibly bestie 💖✨
