XCB + record x11 extension example

Can you provide me example code (on any language) which use record extension via XCB? There are many examples of how to do it with Xlib (https://gist.github.com/whym/402801) but I can't understand how to translate this part of Xlib code to XCB:

# Create a recording context; we only want key and mouse events
ctx = record_dpy.record_create_context(
    0,
    [record.AllClients],
    [{
        'core_requests': (0, 0),
        'core_replies': (0, 0),
        'ext_requests': (0, 0, 0, 0),
        'ext_replies': (0, 0, 0, 0),
        'delivered_events': (0, 0),
        'device_events': (X.KeyPress, X.KeyPress),
        'errors': (0, 0),
        'client_started': False,
        'client_died': False,
    }]
)

XCB docs for xcb_record_create_context(...) is totally mess. Any working code will be helpful.
