 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.
