XtIsTopLevelShell tests whether a widget is a subclass of the TopLevelShell widget class. This is really just a convenience function equivalent to calling XtIsSubclass with topLevelShellWidgetClass as the object_class argument. XtIsTopLevelShell is defined as a macro in <X11/Intrinsic.h>:
#define XtIsTopLevelShell(widget) (_XtCheckSubclassFlag(widget, (XtEnum)0x80))
