    menu_mark(3x)                                                    menu_mark(3x)

## NAME

           set_menu_mark, menu_mark - get and set the menu mark string

## 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

           curses(3x), menu(3x).

## 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.
