mitem_new(3X)                                              mitem_new(3X)

NAME         top

       new_item, free_item - create and destroy menu items

SYNOPSIS         top

       #include <menu.h>

       ITEM *new_item(const char *name, const char *description);
       int free_item(ITEM *item);

DESCRIPTION         top

       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         top

       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.

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
