wn_cursor_update_pixel

	status.i4.v = wn_cursor_update_pixel(x.i4.r, y.i4.r [,window_id.i4.r]
					     [,screen.i4.r])

	This routine returns the present pixel coordinates where the
	graphic cursor is located.

	x, y		returned pixel coordinates of present cursor position
	[window_id]	returned window ID where cursor is located
			(Note: If the cursor lies within multiple overlapping
			 windows and one of those windows is the presently
			 active window, the active window ID will be returned.
			 Otherwise, the topmost window ID will be returned.)
			(default is NULL)
	[screen]	returned screen where cursor is located
