menu_new(3MENU)                                                menu_new(3MENU)

NAME
       menu_new - create and destroy menu items

SYNOPSIS
       #include <menu.h>
       ITEM *new_item(const char *name, const char *description);
       int free_item(ITEM *item);

DESCRIPTION
       The  function new_item allocates a new item and initializes it from the
       name and description pointers. Please notice that the item stores  only
       the  pointers to the name and description. Those pointers must be valid
       during the lifetime of the item. So you should  be  very  careful  with
       names or descriptions allocated on the stack of some routines.
       The  function  free_item de-allocates an item. Please notice that it is
       the responsibility of the application to release  the  memory  for  the
       name or the description of the item.

RETURN VALUE
       The  function  new_item returns NULL on error.  It sets errno according
       to the function's failure:

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_SYSTEM_ERROR
            System error occurred, e.g., malloc failure.

       The function free_item returns one of the following:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_CONNECTED
            Item is connected to a menu.

       E_SYSTEM_ERROR
            System error occurred (see errno).

SEE ALSO
       ncurses(3NCURSES), menu(3MENU).

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 sup-
       ported on Version 7 or BSD versions.
