SYNOPSIS
     #include <xcb/damage.h>

   Request function
     xcb_damage_query_version_cookie_t	    xcb_damage_query_version(xcb_connec-
	    tion_t *conn,   uint32_t client_major_version,   uint32_t client_mi-
	    nor_version);

   Reply datastructure
     typedef struct xcb_damage_query_version_reply_t {
	 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];
     } xcb_damage_query_version_reply_t;

   Reply function
     xcb_damage_query_version_reply_t	*xcb_damage_query_version_reply(xcb_con-
	    nection_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_VERSION.
	       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.
