new_item, free_item - create and destroy menu items
#include <menu.h>
ITEM *new_item(const char *name, const char *description);
int free_item(ITEM *item);
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.
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).
curses(3X), menu(3X).
The header file <menu.h> automatically includes the header file
<curses.h>.
These routines emulate the System V menu library. They were not
supported on Version 7 or BSD versions.
