       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.

       Tk_GetVRootGeometry 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 win-
       dow 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 does not 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
