NAME
new_item,
free_item -
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 d-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 ou-o-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 ou-o-range argument.
- E_CONNECTED
-
Item is connected to a menu.
- 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.
