menu_mark(3x)                    Library calls                   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)).

PORTABILITY

       These  routines  emulate  the  System  V  menu  library.  They were not
       supported on Version 7 or BSD versions.
