Create and destroy menus
#include <menu.h>
MENU *new_menu(ITEM **items);
int free_menu(MENU *menu);
The function new_menu creates a new menu connected to a specified item pointer array (which must be NULL-terminated).
The function free_menu disconnects menu from its item array and frees the storage allocated for the menu.
The function new_menu returns NULL on error. It sets errno according to the function's failure:
E_NOT_CONNECTED
No items are connected to the menu.
E_SYSTEM_ERROR
System error occurred, e.g., malloc failure.
The function free_menu returns one of the following:
E_OK
The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_POSTED
The menu has already been posted.
ncurses(3NCURSES), menu(3MENU).
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.
