En primer lugar, realiza los mismos pasos que el constructor por defecto, entonces asssociate la corriente con un archivo llamando
rdbuf()->open(filename, mode | std::ios_base::out).. Si la llamada open () devuelve un puntero nulo, se establece setstate(failbit) .Original:
First, performs the same steps as the default constructor, then asssociate the stream with a file by calling
rdbuf()->open(filename, mode | std::ios_base::out).. If the open() call returns a null pointer, sets setstate(failbit).The text has been machine-translated via Google Translate.

Mueva constructor. En primer lugar, se mueven-construye la clase base de

other (which does not affect the rdbuf() pointer), then move-constructs the std::basic_filebuf member, then calls this->set_rdbuf() to install the new basic_filebuf as the rdbuf() pointer in the base class.The text has been machine-translated via Google Translate.
