REPLY FIELDS response_type The type of this reply, in this case XCB_COMPOSITE_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 Composite extension. It must be precede all other requests using Composite. Failure to do so will cause a BadRequest error. RETURN VALUE Returns an xcb_composite_query_version_cookie_t. Errors have to be han- dled when calling the reply function xcb_composite_query_version_reply. If you want to handle errors in the event loop instead, use xcb_compos- ite_query_version_unchecked. See xcb-requests(3) for details. ERRORS This request does never generate any errors.
