Function sdl2_sys::SDL_SetWindowGammaRamp

pub unsafe extern "C" fn SDL_SetWindowGammaRamp(
    window: *mut SDL_Window, 
    red: *const Uint16, 
    green: *const Uint16, 
    blue: *const Uint16
) -> c_int

\brief Set the gamma ramp for a window.

\param window The window for which the gamma ramp should be set. \param red The translation table for the red channel, or NULL. \param green The translation table for the green channel, or NULL. \param blue The translation table for the blue channel, or NULL.

\return 0 on success, or -1 if gamma ramps are unsupported.

Set the gamma translation table for the red, green, and blue channels of the video hardware. Each table is an array of 256 16-bit quantities, representing a mapping between the input and output for that channel. The input is the index into the array, and the output is the 16-bit gamma value at that index, scaled to the output color precision.
