## 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.

## 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.
