sdlGetRenderDrawColor function render

bool sdlGetRenderDrawColor(Pointer<SdlRenderer> renderer, Pointer<Uint8> r, Pointer<Uint8> g, Pointer<Uint8> b, Pointer<Uint8> a,)

Get the color used for drawing operations (Rect, Line and Clear).

\param renderer the rendering context. \param r a pointer filled in with the red value used to draw on the rendering target. \param g a pointer filled in with the green value used to draw on the rendering target. \param b a pointer filled in with the blue value used to draw on the rendering target. \param a a pointer filled in with the alpha value used to draw on the rendering target; usually SDL_ALPHA_OPAQUE (255). \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
