	   uint8_t  response_type;
	   uint8_t  pad0;
	   uint16_t sequence;
	   uint32_t length;
	   uint32_t major_version;
	   uint32_t minor_version;
	   uint8_t  pad1[16];

   Reply function

       xcb_damage_query_version_reply_t
	      *xcb_damage_query_version_reply(xcb_connection_t *conn,
	      xcb_damage_query_version_cookie_t	cookie,
	      xcb_generic_error_t **e);

REQUEST	ARGUMENTS
       conn	 The XCB connection to X11.

       client_major_version
		 The major version supported by	the client.

       client_minor_version
		 The minor version supported by	the client.

REPLY FIELDS
       response_type
		 The  type  of	this reply, in this case XCB_DAMAGE_QUERY_VER-
		 SION. 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).

       major_version
		 The major version chosen by the server.

       minor_version
		 The minor version chosen by the server.

DESCRIPTION
       This negotiates the version of the DAMAGE extension.  It	 must  precede
       any  other  request  using the DAMAGE extension.	 Failure to do so will
       cause a BadRequest error	for those requests.

RETURN VALUE
       Returns an xcb_damage_query_version_cookie_t. Errors have to be handled
       when calling the	reply function xcb_damage_query_version_reply.

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

ERRORS
       This request does never generate	any errors.
