Look in X11/XCB/xproto.h for XCBGetProperty() and any other core X requests, 
replies, and types.

Look in X11/XCB/xcb_atom.h for XCB's versions of predefined atoms (CARDINAL 
instead of XA_CARDINAL).

Look in xcb/xcb-util/property/ for some possibly useful code and utility functions 
relating to properties.

Also look in xcb/xcb-demo for other useful code about XCB in general.

P.S. You need not copy the xorg list.  These questions are pretty specific to XCB.
