SDL_disabled_assert - Man Page

#include <SDL3/SDL_assert.h>

#define SDL_disabled_assert(condition) \
    do { (void) sizeof ((condition)); } while (SDL_NULL_WHILE_LOOP_CONDITION)

This isn't for direct use by apps, but this is the code that is inserted when an SDL_assert is disabled (perhaps in a release build).

The code does nothing, but wraps condition in a sizeof operator, which generates no code and has no side effects, but avoid compiler warnings about unused variables.

condition

the condition to assert (but not actually run here).

This macro is available since SDL 3.2.0.
