       Tk_GetVRootGeometry - Get location and size of virtual root for window

       #include	<tk.h>

       Tk_GetVRootGeometry(tkwin, xPtr,	yPtr, widthPtr,	heightPtr)

       Tk_Window   tkwin       (in)	 Token	for  window whose virtual root
					 is to be queried.

       int	   xPtr	       (out)	 Points	to word	in which to  store  x-
					 offset	of virtual root.

       int	   yPtr	       (out)	 Points	 to  word in which to store y-
					 offset	of virtual root.

       int	   widthPtr    (out)	 Points	to  word  in  which  to	 store
					 width of virtual root.

       int	   heightPtr   (out)	 Points	 to  word  in  which  to store
					 height	of virtual root.

       TkGetVRootGeometry returns geometry information about the virtual  root
       window  associated  with	tkwin.	The ``associated'' virtual root	is the
       one in which tkwin's nearest top-level ancestor (or tkwin itself	if  it
       is a top-level window) has been reparented by the window	manager.  This
       window is identified by a __SWM_ROOT or __WM_ROOT  property  placed  on
       the top-level window by the window manager.  If tkwin is	not associated
       with a virtual root (e.g.  because the window manager doesn't use  vir-
       tual  roots)  then  *xPtr  and *yPtr will be set	to 0 and *widthPtr and
       *heightPtr will be set to the dimensions	of the screen  containing  tk-

       geometry, height, location, virtual root, width,	window manager
