  63        In  order  to make menu selections visible on older termi-
  64        nals without highlighting or color  capability,  the  menu
  65        library  marks  selected  items  in  a  menu with a prefix
  66        string.
  67
  68        The function <STRONG>set_menu_mark</STRONG> sets the mark  string  for  the
  69        given  menu.   Calling <STRONG>set_menu_mark</STRONG> with a null menu item
  70        will abolish the mark  string.   Note  that  changing  the
  71        length  of  the  mark  string for a menu while the menu is
  72        posted is likely to produce unhelpful behavior.
  73
  74        The default string is "-" (a dash). Calling  <STRONG>set_menu_mark</STRONG>
  75        with a non-<STRONG>NULL</STRONG> menu argument will change this default.
  76
  77        The  function <STRONG>menu_mark</STRONG> returns the menu's mark string (or
  78        <STRONG>NULL</STRONG> if there is none).

  82 <H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  83        The function <STRONG>menu_mark</STRONG> returns a  pointer  (which  may  be
  84        <STRONG>NULL</STRONG>).  It does not set errno.
  85
  86        The  function <STRONG>set_menu_mark</STRONG> may return the following error
  87        codes:
  88
  89        <STRONG>E_OK</STRONG> The routine succeeded.
  90
  91        <STRONG>E_BAD_ARGUMENT</STRONG>
  92             Routine detected an incorrect or  out-of-range  argu-

  96             System error occurred (see <STRONG>errno</STRONG>).
