sdlGetRenderDrawColor function

int sdlGetRenderDrawColor(
  1. Pointer<SdlRenderer> renderer,
  2. Pointer<Uint8> r,
  3. Pointer<Uint8> g,
  4. Pointer<Uint8> b,
  5. 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 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
