Use this function to get the gamma ramp for the display that owns a given window.

<<TableOfContents()>>

== Syntax ==
{{{#!highlight cpp
int SDL_GetWindowGammaRamp(SDL_Window* window,
                           Uint16*     red,
                           Uint16*     green,
                           Uint16*     blue)
}}}

== Function Parameters ==
||'''window'''||the window used to select the display whose gamma ramp will be queried||
||'''red'''||a 256 element array of 16-bit quantities filled in with the translation table for the red channel, or NULL||
||'''green'''||a 256 element array of 16-bit quantities filled in with the translation table for the green channel, or NULL||
||'''blue'''||a 256 element array of 16-bit quantities filled in with the translation table for the blue channel, or NULL||

== Return Value ==
Returns 0 on success or a negative error code on failure; call [[SDL_GetError]]() for more information.

== Remarks ==
Despite the name and signature, this method retrieves the gamma ramp of the entire display, not an individual window. A window is considered to be owned by the display that contains the window's center pixel. (The index of this display can be retrieved using [[SDL_GetWindowDisplayIndex]]().)
