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(3)).

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
       supported on Version 7 or BSD versions.
