NAME
       Tk_GetRootCoords - Compute root-window coordinates of win-
       dow

SYNOPSIS
       #include <tk.h>

       Tk_GetRootCoords(tkwin, xPtr, yPtr)

ARGUMENTS
       Tk_Window   tkwin   (in)	     Token for window.

       int	   *xPtr   (out)     Pointer to location in which
				     to store root-window x-coor-
				     dinate corresponding to left
				     edge of tkwin's border.

       int	   *yPtr   (out)     Pointer to location in which
				     to store root-window y-coor-
				     dinate  corresponding to top
				     edge of tkwin's border.

DESCRIPTION
       This procedure scans through  the  structural  information
       maintained  by  Tk  to compute the root-window coordinates
       corresponding to the upper-left corner of tkwin's  border.
       If  tkwin has no border, then Tk_GetRootCoords returns the
       root-window coordinates corresponding to location (0,0) in
       tkwin.  Tk_GetRootCoords is relatively efficient, since it
       doesn't have to communicate with the X server.
