One way I know of is through the ICCCM convenience functions:
    XGetClassHint(Display *, Window, XClassHint *)

Also, the info is stored in the ApplicationShell (created by XtInitialize)
in the xrm_class and/or class fields.

You could probably cheat by:
    XrmClass c;
    char *class;
    ApplicationShellWidget a;

    a = (ApplicationShellWidget) XtInialize(...)
    c = a->application.xrm_class;
    class = a->application.class;
    ...

I would suggest something like:
    toplevel = XtInitialize(...);
    XGetClassHint(XtDisplay(toplevel), XtWindow(toplevel), &classHint);

Or maybe....
