    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).
     

    SEE ALSO

    curses(3X), menu(3X).  

    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.
