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.

KEYWORDS
