NAME

       mitem_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 life-
       time 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  argu-
            ment.

       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 argu-
            ment.

       E_CONNECTED
            Item is connected to a menu.

       E_SYSTEM_ERROR
            System error occurred (see errno).
