NAME
     Tk_GetRootCoords - Compute root-window coordinates of window

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-
                                   coordinate  corresponding   to
                                   left edge of tkwin's border.

     int         *yPtr   (out)     Pointer to location  in  which
                                   to    store   root-window   y-
                                   coordinate  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.
