           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_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_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_damage_query_version_unchecked. See xcb-requests(3) for details.

ERRORS

       This request does never generate any errors.
