| * |
| * If you use this function and you haven't used the SDL_INIT_VIDEO flag with |

| * before calling SDL_Quit(). |

| * It is safe to call this function multiple times. SDL_VideoInit() will call |
| * SDL_VideoQuit() itself if the video subsystem has already been initialized. |
| * |
| * You can use SDL_GetNumVideoDrivers() and SDL_GetVideoDriver() to find a |
| * specific `driver_name`. |
| * |
| * \param driver_name the name of a video driver to initialize, or NULL for |
| * the default driver |
| * \returns 0 on success or a negative error code on failure; call |
| * SDL_GetError() for more information. |
