Function sdl2_sys::SDL_SetAssertionHandler

pub unsafe extern "C" fn SDL_SetAssertionHandler(
    handler: SDL_AssertionHandler,
    userdata: *mut c_void,
)

Set an application-defined assertion handler.

This function allows an application to show its own assertion UI and/or force the response to an assertion failure. If the application doesn’t provide this, SDL will try to do the right thing, popping up a system-specific GUI dialog, and probably minimizing any fullscreen windows.

This callback may fire from any thread, but it runs wrapped in a mutex, so it will only fire from one thread at a time.

This callback is NOT reset to SDL’s internal handler upon SDL_Quit()!

\param handler the SDL_AssertionHandler function to call when an assertion fails or NULL for the default handler \param userdata a pointer that is passed to handler

\since This function is available since SDL 2.0.0.
