Function SDL_GetAssertionHandler

Help

pub unsafe extern "C" fn SDL_GetAssertionHandler(
    puserdata: *mut *mut c_void,
) -> Option<unsafe extern "C" fn(_: *const SDL_AssertData, _: *mut c_void) -> SDL_AssertState> ⓘ

Available on crate feature dep_sdl3 only.

Expand description

Get the current assertion handler.

This returns the function pointer that is called when an assertion is triggered. This is either the value last passed to SDL_SetAssertionHandler(), or if no application-specified function is set, is equivalent to calling SDL_GetDefaultAssertionHandler().

The parameter puserdata is a pointer to a void*, which will store the “userdata” pointer that was passed to SDL_SetAssertionHandler(). This value will always be NULL for the default handler. If you don’t care about this data, it is safe to pass a NULL pointer to this function to ignore it.

§Parameters

puserdata: pointer which is filled with the “userdata” pointer that was passed to SDL_SetAssertionHandler().

§Return value

Returns the SDL_AssertionHandler that is called when an assert triggers.

§Thread safety

It is safe to call this function from any thread.

§Availability

This function is available since SDL 3.2.0.
