(2)
basic_filebuf( std::basic_filebuf&& rhs );
(3) (dal C++11)
1)
Costruisce un oggetto std::basic_filebuf, l'inizializzazione della classe base chiamando il costruttore predefinito di std::basic_streambuf. Il basic_filebuf creato non è associato a un file e ritorna is_open() false.
Original:
Constructs a std::basic_filebuf object, initializing the base class by calling the default constructor of std::basic_streambuf. The created basic_filebuf is not associated with a file, and is_open() returns false.

3)
Move-costruisce un oggetto std::basic_filebuf spostando tutto il contenuto da un altro oggetto std::basic_filebuf rhs, compresi i buffer, il file associato, il locale, il openMode, la variabile is_open, e tutto altro Stato. Dopo la mossa, rhs non è associato a un file e rhs.is_open()==false. I puntatori membri della classe base std::basic_streambuf di rhs e della classe base di *this sono garantiti per puntare al buffer differenti (a meno che non null).
Original:
Move-constructs a std::basic_filebuf object by moving all contents from another std::basic_filebuf object rhs, including the buffers, the associated file, the locale, the openmode, the is_open variable, and all other state. After move, rhs is not associated with a file and rhs.is_open()==false. The member pointers of the base class std::basic_streambuf of rhs and of the base class of *this are guaranteed to point to different buffers (unless null).
