SDL_assert_paranoid(3)

💅 SDL_assert_paranoid 💅

okay bestie, so like... this is SDL_assert_paranoid, from the SDL3 functions era, and it's the extra-spicy assertion check that only shows up when you built your stuff with paranoid settings. yes, that's really the name. we love a dramatic queen. 👑

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_assert.h>

#define SDL_assert_paranoid(condition) SDL_disabled_assert(condition)

---

🌸 DESCRIPTION 🌸

so here's the tea 🍓 — this macro is enabled when SDL_ASSERT_LEVEL is >= 3, and otherwise it's just... off. napping. not the moment.

and ngl, that's a higher level than both release and debug, which means these tests are literally meant to be expensive. like, designer-bag expensive. 💅 they only run when you're specifically hunting for extremely unexpected failure cases in a special build. it's giving forensic investigator energy, fr fr.

When assertions are disabled, this wraps condition in a sizeof operator — which means any function calls and side effects will not run, but the compiler won't complain about any otherwise-unused variables that are only referenced in the assertion. sneaky? no. iconic? yes. 😌

One can set the environment variable "SDL_ASSERT" to one of several strings to force a default behavior, which may be desirable for automation purposes:

• "abort"
• "break"
• "retry"
• "ignore"
• "always_ignore"

and bestie, listen — if your platform requires GUI interfaces to happen on the main thread but you're debugging an assertion in a background thread, it might be desirable to set this to "break" so that your debugger takes control as soon as assert is triggered, instead of risking a bad UI interaction (deadlock, etc) in the application. 😭 the way that would absolutely ruin your whole afternoon... set it to "break", i'm begging.

🫶 real talk: this is a caveat, not a suggestion. deadlocks are not cute. they are not the vibe. set "break" and let your debugger handle it.
