pub unsafe extern "C" fn SDL_SetRenderDrawColor(

    g: Uint8,
    b: Uint8,
    a: Uint8
) -> c_int

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

Set the color for drawing or filling rectangles, lines, and points, and for SDL_RenderClear().

\param renderer the rendering context \param r the red value used to draw on the rendering target \param g the green value used to draw on the rendering target \param b the blue value used to draw on the rendering target \param a the alpha value used to draw on the rendering target; usually SDL_ALPHA_OPAQUE (255). Use SDL_SetRenderDrawBlendMode to specify how the alpha channel is used \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.
