SYNOPSIS
       #include <menu.h>
       int set_menu_mark(MENU *menu, const char *mark);
       const char *menu_mark(const MENU *menu);

DESCRIPTION
       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  set_menu_mark  sets  the mark string for the given menu.
       Calling set_menu_mark 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 set_menu_mark with  a  non-
       NULL menu argument will change this default.

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

RETURN VALUE
       The function menu_mark returns a pointer (which may be NULL).  It  does
       not set errno.

       The function set_menu_mark may return the following error codes:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_SYSTEM_ERROR
            System error occurred (see errno).

SEE ALSO
       ncurses(3NCURSES), menu(3MENU).

NOTES
       The  header  file  <menu.h>  automatically  includes  the  header  file
       <curses.h>.

PORTABILITY
       These routines emulate the System V menu library.  They were  not  sup-
       ported on Version 7 or BSD versions.
