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

       colors_len
                 TODO: NOT YET DOCUMENTED.

conn      The XCB connection to X11.

       cmap      TODO: NOT YET DOCUMENTED.

       pixels_len
                 TODO: NOT YET DOCUMENTED.

       pixels    TODO: NOT YET DOCUMENTED.

       Returns an xcb_query_colors_cookie_t.  Errors  have  to  be  handled  when  calling  the  reply  function
       xcb_query_colors_reply.

       If  you  want  to  handle  errors  in the event loop instead, use xcb_query_colors_unchecked. See xcb-re‐quests(3) for details.
