NAME¶

SDL_assert_release - An assertion test that is performed even in release builds.

HEADER FILE¶

Defined in SDL3/SDL_assert.h

SYNOPSIS¶

#include "SDL3/SDL.h"

#define SDL_assert_release(condition) SDL_disabled_assert(condition)

DESCRIPTION¶

This macro is enabled when the SDL_ASSERT_LEVEL
is >= 1, otherwise it is disabled. This is meant to be for tests that are cheap to make and extremely unlikely to fail; generally it is frowned upon to have an assertion failure in a release build, so these assertions generally need to be of more than life-and-death importance if there's a chance they might trigger. You should almost always consider handling these cases more gracefully than an assert allows.

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 will not complain about any otherwise-unused variables that are only referenced in the assertion.

One can set the environment variable " SDL_ASSERT " to one of several strings ("abort", "break", "retry", "ignore", "always_ignore") to force a default behavior, which may be desirable for automation purposes. 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.

Note that SDL_ASSERT
is an _environment variable_ and not an SDL hint! Please refer to your platform's documentation for how to set it!

AVAILABILITY¶

This macro is available since SDL 3.0.0.
