Function sdl2_sys::SDL_WaitEvent

pub unsafe extern "C" fn SDL_WaitEvent(event: *mut SDL_Event) -> c_int

Wait indefinitely for the next available event.

If event is not NULL, the next event is removed from the queue and stored in the SDL_Event structure pointed to by event.

As this function may implicitly call SDL_PumpEvents(), you can only call this function in the thread that initialized the video subsystem.

\param event the SDL_Event structure to be filled in with the next event from the queue, or NULL \returns 1 on success or 0 if there was an error while waiting for events; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
