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.

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.

This request does never generate any errors.
