SDL_disabled_assert(3)

✨ NAME ✨

SDL_disabled_assert — the macro that shows up when an assertion is disabled. it's the "we're not checking but we're still cute about it" era 💅

this one lives in the SDL3 FUNCTIONS manual, bestie, and yes it's exactly as niche as it sounds 🫶

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_assert.h>

#define SDL_disabled_assert(condition) \
    do { (void) sizeof ((condition) ? 1 : 0); } while (SDL_NULL_WHILE_LOOP_CONDITION)

---

💖 DESCRIPTION 💖

okay so first things first: this is not for direct use by apps. like, don't call it, don't text it back, it's not your macro to use 🙈. it's the code that gets inserted when an SDL_assert is disabled — think release build energy, where the checks are gone but the vibes remain ✨.

and what does that code actually do? literally nothing 💀. no cap, it does nothing. but here's the slay part: it wraps condition in a sizeof operator, and that sizeof generates no code and has no side effects — so it's free, bestie, it costs you nothing.

so why even bother? because it:

• avoids compiler warnings about unused variables (the compiler stays quiet, we stay unbothered 🎀)
• still checks syntax even when disabled (syntax check never takes a day off 👑)

it's giving "I'm not doing the work but I'm still showing up to class" and honestly? iconic.

---

🦋 MACRO PARAMETERS 🦋

• condition — the condition to assert. (but it does not actually run here, bestie — it just gets looked at. eyes only, no execution 💅)

---

🌈 AVAILABILITY 🌈

this macro has been around since SDL 3.2.0. so if you're on anything older... not me finding out the hard way 😭

and that's the whole page fr fr 🍓 — brought to you by the Simple Directmedia Layer girlies, straight out of SDL 3.4.18. go forth and let your disabled asserts be syntactically valid, mwah 💜🧚
