response_type
                 The  type  of this reply, in this case XCB_SHM_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).

       shared_pixmaps
                 True if the server supports shared pixmaps, otherwise false.

       major_version
                 The major version of the extension supported.

       minor_version
                 The minor version of the extension supported.

       uid       The UID of the server.

       gid       The GID of the server.

       pixmap_format
                 TODO: NOT YET DOCUMENTED.

conn      The XCB connection to X11.

       Returns an xcb_shm_query_version_cookie_t. Errors have to be handled  when  calling  the  reply  function
       xcb_shm_query_version_reply.

       If  you want to handle errors in the event loop instead, use xcb_shm_query_version_unchecked. See xcb-re‐quests(3) for details.
