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 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(3)).
PORTABILITY¶
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
