The XCB connection to X11.

The type of this reply, in this case XCB_LIST_EXTENSIONS. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.
The sequence number of the last request processed by the X11 server.
The length of the reply, in words (a word is 4 bytes).
TODO: NOT YET DOCUMENTED.

Returns an xcb_list_extensions_cookie_t. Errors have to be handled when calling the reply function xcb_list_extensions_reply.

If you want to handle errors in the event loop instead, use xcb_list_extensions_unchecked. See xcb-requests(3) for details.

This request does never generate any errors.
