std::basic_filebuf è un std::basic_streambuf cui associata sequenza di caratteri è un file. Sia la sequenza di ingresso e la sequenza di uscita sono associati con lo stesso file, ed una posizione di file di articolazione viene mantenuta per entrambe le operazioni.

Original:

std::basic_filebuf is a std::basic_streambuf whose associated character sequence is a file. Both the input sequence and the output sequence are associated with the same file, and a joint file position is maintained for both operations.

Il underflow funzioni () e troppo pieno () / sync () eseguire l'I / O tra il file e le aree get e put del buffer. Quando CharT non è char, maggior parte delle implementazioni di memorizzare i caratteri multibyte nel file e una sfaccettatura std::codecvt viene utilizzato per eseguire gamma / multibyte conversione dei caratteri.

Original:

The functions underflow() and overflow()/sync() perform the actual I/O between the file and the get and put areas of the buffer. When CharT is not char, most implementations store multibyte characters in the file and a std::codecvt facet is used to perform wide/multibyte character conversion.
