REQUEST ARGUMENTS

       conn      The XCB connection to X11.

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.
