       and anchor positions

SYNOPSIS
       #include <tk.h>

       Tk_GetAnchor(interp, string, anchorPtr)

       char *
       Tk_NameOfAnchor(anchor)

ARGUMENTS
       Tcl_Interp  *interp	(in)	  Interpreter to use  for
					  error reporting.

       char	   *string	(in)	  String  containing name
					  of anchor point: one of
					  ``n'',  ``ne'',  ``e'',
					  ``se'', ``s'',  ``sw'',
					  ``w'',    ``nw'',    or
					  ``center''.

       int	   *anchorPtr	(out)	  Pointer to location  in

_________________________________________________________________

DESCRIPTION
       Tk_GetAnchor places in *anchorPtr an anchor position (enu-
       merated	type  Tk_Anchor)  corresponding to string,  which
       will be one  of	TK_ANCHOR_N,  TK_ANCHOR_NE,  TK_ANCHOR_E,
       TK_ANCHOR_SE,   TK_ANCHOR_S,   TK_ANCHOR_SW,  TK_ANCHOR_W,
       TK_ANCHOR_NW, or TK_ANCHOR_CENTER.  Anchor  positions  are
       typically  used	for  indicating a point on an object that
       will be used to position	 that  object,	e.g.  TK_ANCHOR_N
       means  position	the  top  center point of the object at a
       particular place.

       Under normal circumstances the return value is TCL_OK  and
       interp  is  unused.   If	 string	 doesn't  contain a valid
       anchor position or an abbreviation of one of these  names,
       then   an  error	 message  is  stored  in  interp->result,
       TCL_ERROR is returned, and *anchorPtr is unmodified.

       Tk_NameOfAnchor is the logical  inverse	of  Tk_GetAnchor.

       Given  an anchor position such as TK_ANCHOR_N it returns a
       statically-allocated string corresponding to  anchor.   If
       anchor  isn't  a legal anchor value, then ``unknown anchor
       position'' is returned.

KEYWORDS
