You don't have to do this with R4.  Why not use ..

	XtToolkitInitialize();
	dpy = XtOpenDisplay(XtCreateApplicationContext(), NULL,
				"xlock", "XLock", options, XtNumber(options),
				&argc, argv);
	shell = XtVaAppCreateShell("xlock", "XLock", overrideShellWidgetClass,
				dpy, XtNwidth, 100, ...., NULL);
??
(I'll send you a full test program if you want).

I assume the "App" part of the Xt{Va}AppCreateShell() comes from the
"per display data" of the passed display pointer (?).

Hmm..  yes there is...  XtVaAppCreateShell() in Xt/VarCreate.c

If you decide to do things this way then why not use Xt{Va}AppInitialize() ?
XtInitialize() is old hat 8-).
