sdlGetRenderDrawColorFloat function

bool sdlGetRenderDrawColorFloat(
  1. Pointer<SdlRenderer> renderer,
  2. Pointer<Float> r,
  3. Pointer<Float> g,
  4. Pointer<Float> b,
  5. Pointer<Float> 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. \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 3.1.3.
