menu_mark(3X)                                       menu_mark(3X)

NAME
       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 termi-
       nals 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 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 NULL on error.   The  func-
       tion set_menu_mark may return the following error codes:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno).

       E_BAD_ARGUMENT
            Routine  detected  an incorrect or out-of-range argu-
            ment.

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.
