Get the shape parameters of a shaped window.
int SDL_GetShapedWindowMode(SDL_Window *window,SDL_WindowShapeMode *shape_mode);
|window||The shaped window whose parameters should be retrieved.|
|shape_mode||An empty shape-mode structure to fill, or NULL to check whether the window has a shape.|
Return 0 if the window has a shape and, provided shape_mode was not NULL, shape_mode has been filled with the mode data, SDL_NONSHAPEABLE_WINDOW if the SDL_Window given is not a shaped window, or SDL_WINDOW_LACKS_SHAPE if the SDL_Window given is a shapeable window currently lacking a shape.
This function is available since SDL 2.0.0.
