I should also point out in here:
 
    cur_desktop = XInternAtom(dpy, "_NET_CURRENT_DESKTOP", True);
    fprintf(stderr, "Atom(_NET_CURRENT_DESKTOP)=%d\n", cur_desktop);
    if (cur_desktop == None) {
      fprintf(stderr, "_NET_CURRENT_DESKTOP is unsupported\n");
      exit(1);
    }

This isn't the correct way to check for support. You should query:

a) _NET_SUPPORTING_WM_CHECK, and make sure the window it points to
exists and is correct.
b) _NET_SUPPORTED for the presence of _NET_CURRENT_DESKTOP in the list.
