## 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  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 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 argu-
                ment.

           E_SYSTEM_ERROR
                System error occurred (see errno).

## 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.
