exposed.i4.v = window_intype_again(window_id.i2.r, type.i2.r, row.i4.r,
					   column.i4.r, info.i4.r

	This routine returns the interrupt information that was returned
	by the last call to window_intype.

	window_id	returned ID of interrupt window (or CBS_WINDOW_OCCLUDED
			if the interrupt window was occluded)
	type		returned interrupt type
			(INTINI -> program initialization (occurs once),
			 INTTRM -> program termination (occurs once),
			 INTKBD -> keyboard interrupt (return key or left
				   mouse button) (primary applications only),
			 INT_SHIFT_KBD -> shift click interrupt,
			 INT_CTRL_KBD -> control click interrupt,
			 INT_ALT_KBD -> alt click interrupt,
			 INTPER -> periodic interrupt (currently 15 Hz),
			 INTKUP -> button up event (follows INTKBD),
			 INTDBL -> double interrupt,
			 INTKBD_LX -> keyboard interrupt in active graphics
				      window (return key or left mouse button),
			 INT_SHIFT_KBD_LX -> shift click interrupt in active
					     graphics window,
			 INT_CTRL_KBD_LX -> control click interrupt in active
					    graphics window,
			 INT_ALT_KBD_LX -> alt click interrupt in active
					   graphics window,
			 INT_FOCUSIN -> TV window has just received focus,
			 INT_FOCUSOUT -> TV window has just lost focus)
	row, column	returned window coordinate location of most recent
			interrupt (Note: Full screen coordinates are returned
			if the interrupt window was occluded.)
	info		returned window information
			(WMNGR_NO_SPECIAL -> no special interrupts detected,
			 WMNGR_SCROLL_UP -> scroll window up one line,
			 WMNGR_SCROLL_UP_PAGE -> scroll window up one page,
			 WMNGR_SCROLL_DOWN -> scroll window down one line,
			 WMNGR_SCROLL_DOWN_PAGE -> scroll window down one page,
			 WMNGR_DRAG_SCROLL_BAR -> drag vertical scroll bar,
			 WMNGR_SCROLL_LEFT -> scroll window left one character,
			 WMNGR_SCROLL_LEFT_PAGE -> scroll window left one page,
			 WMNGR_SCROLL_RIGHT -> scroll window right one
			 WMNGR_SCROLL_RIGHT_PAGE -> scroll window right one
			 WMNGR_DRAG_HSCROLL_BAR -> drag horizontal scroll bar,
			 WMNGR_SCROLL_STATUS -> interrupt in scroll status
			 WMNGR_MOVE -> move this window,
			 WMNGR_RESIZE -> resize this window,
			 WMNGR_WINDOW_POPPED -> window was popped to front)
	[ret_occluded]	flag for determining whether or not to return
			the actual window ID and row and column for an
			occluded window
			(TRUE -> return actual window ID (negated) and
				 window coordinates,
			 FALSE -> return CBS_WINDOW_OCCLUDED and full screen
				  coordinates (default))

	This function returns status values as follows:

	OK			success
	WMNGR_EXPOSED		a window has been exposed
