(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_disabled_assert

The macro used when an assertion is disabled.

Header File

Defined in <SDL3/SDL_assert.h>

Syntax

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

Macro Parameters

condition

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

Remarks

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.

Version

This macro is available since SDL 3.1.3.
