sdlIntersectRect function

bool sdlIntersectRect(Pointer<SdlRect> a, Pointer<SdlRect> b, Pointer<SdlRect> result)

Calculate the intersection of two rectangles.

If result is NULL then this function will return SDL_FALSE.

\param A an SDL_Rect structure representing the first rectangle \param B an SDL_Rect structure representing the second rectangle \param result an SDL_Rect structure filled in with the intersection of rectangles A and B \returns SDL_TRUE if there is an intersection, SDL_FALSE otherwise.

\since This function is available since SDL 2.0.0.
