uint16_t *xcb_randr_get_crtc_gamma_blue(const xcb_randr_get_crtc_gamma_request_t *reply);

int xcb_randr_get_crtc_gamma_blue_length(const xcb_randr_get_crtc_gamma_reply_t *reply);

response_type: The type of this reply, in this case XCB_RANDR_GET_CRTC_GAMMA. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.

sequence: The sequence number of the last request processed by the X11 server.

Returns an xcb_randr_get_crtc_gamma_cookie_t. Errors have to be handled when calling the reply function xcb_randr_get_crtc_gamma_reply.

If you want to handle errors in the event loop instead, use xcb_randr_get_crtc_gamma_unchecked. See xcb-requests(3) for details.

This request does never generate any errors.
