</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       In  order  to  make  menu selections visible on older terminals without
       highlighting or color capability, the menu library marks selected items
       in a menu with a prefix string.

       The  function  <STRONG>set_menu_mark</STRONG>  sets  the mark string for the given menu.
       Calling <STRONG>set_menu_mark</STRONG> with a null  menu  item  will  abolish  the  mark
       string.   Note  that  changing the length of the mark string for a menu
       while the menu is posted is likely to produce unhelpful behavior.

       The default string is "-" (a dash).  Calling <STRONG>set_menu_mark</STRONG> with a  non-
       <STRONG>NULL</STRONG> menu argument will change this default.

       The function <STRONG>menu_mark</STRONG> returns the menu's mark string (or <STRONG>NULL</STRONG> if there
       is none).


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       The function <STRONG>menu_mark</STRONG> returns a pointer (which may be <STRONG>NULL</STRONG>).  It  does
       not set <STRONG>errno</STRONG>.

       The function <STRONG>set_menu_mark</STRONG> may return the following error codes:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_BAD_ARGUMENT</STRONG>
            Routine detected an incorrect or out-of-range argument.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno(3)</STRONG>).
