NAME
     Tk_GetJustify, Tk_NameOfJustify - translate between strings and
     justification styles

SYNOPSIS
     #include <tk.h>

     Tk_Justify
     Tk_GetJustify(interp, string, justifyPtr)

     char *
     Tk_NameOfJustify(justify)

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

     char         *string       (in)      String containing name of           |
                                          justification style (``left'',      |
                                          ``right'', or ``center'').

     int          *justifyPtr   (out)     Pointer to location in which to
                                          store justify value corresponding to
                                          string.

     Tk_Justify   justify       (in)      Justification style (one of the
                                          values listed below).


DESCRIPTION
     Tk_GetJustify places in *justifyPtr the justify value corresponding to
     string.  This value will be one of the following:

     TK_JUSTIFY_LEFT
          Means that the text on each line should start at the left edge of
          the line;  as a result, the right edges of lines may be ragged.

     TK_JUSTIFY_RIGHT
          Means that the text on each line should end at the right edge of the
          line;  as a result, the left edges of lines may be ragged.

     TK_JUSTIFY_CENTER
          Means that the text on each line should be centered;  as a result,
          both the left and right edges of lines may be ragged.

     Under normal circumstances the return value is TCL_OK and interp is
     unused.  If string doesn't contain a valid justification style or an
     abbreviation of one of these names, then an error message is stored in
     interp->result, TCL_ERROR is returned, and *justifyPtr is unmodified.
     Tk_NameOfJustify is the logical inverse of Tk_GetJustify.  Given a
     justify value it returns a statically-allocated string corresponding to
     justify.  If justify isn't a legal justify value, then ``unknown
     justification style'' is returned.
