REPLY FIELDS

       response_type
                 The type of this reply, in this case XCB_GET_IMAGE. 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).

       depth     TODO: NOT YET DOCUMENTED.

       visual    TODO: NOT YET DOCUMENTED.


DESCRIPTION


RETURN VALUE

       Returns an xcb_get_image_cookie_t. Errors have to be handled when
       calling the reply function xcb_get_image_reply.

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


ERRORS

       This request does never generate any errors.
