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 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).

NOTES

The header file <menu.h> automatically includes the header file
<curses.h>.
 

PORTABILITY

These routines emulate the System V menu library. They were not supported on
Version 7 or BSD versions.
