X is client-server.
Xlib is client-side.
Modules are server-side.
You should to find the code in Xlib for the routines you are interested
in, and see which X requests that code makes to the server.
Then you need to find the the server code that implements those requests
and see how that code does it.
You may be able to short circuit some of this.
As a hint, Xlib code is in
xc/lib
and X server code is in
xc/programs/Xserver
