REQUEST ARGUMENTS

       conn      The XCB connection to X11.

REPLY FIELDS

       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.

       length    The length of the reply, in words (a word is 4 bytes).

       size      TODO: NOT YET DOCUMENTED.


DESCRIPTION


RETURN VALUE

       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.


ERRORS

       This request does never generate any errors.
