I found those values by looking into the source code, probably libxcb's, since they are passed to the second argument of the function xcb_send_request(), as can be seen here (although the "sequence" argument is gone already): <a href="https://xcb.freedesktop.org/ProtocolExtensionApi/#index3h2" id="LPlnk651532">https://xcb.freedesktop.org/ProtocolExtensionApi/#index3h2</a> but
that page doesn't explain what they do.</div>

My goal with this tutorial is to provide enough for the reader to understand the X documentation so he is able to "navigate" on his own, that is what I am trying to do myself.</div>

Those values are for internal use by libxcb (and/or xlib), and are not intended to be used by a normal user of libxcb.<br>
<br>
Who is your tutorial intended for? Showing the inner workings is more of a "deep documentation" thing than a "tutorial" thing.<br>

libxcb is a thin wrapper around the X11 protocol. As such, the documentation for those fields can be found at:<br>
