template<     class charT,     class Traits = std::char_traits<CharT>,     class Allocator = std::allocator<CharT> > class basic_filebuf : public std::basic_streambuf<CharT, Traits>

std::basic_filebuf es un std::basic_streambuf cuya secuencia de caracteres asociados es un archivo. Tanto la secuencia de entrada y la secuencia de salida están asociados con el mismo archivo, y una posición de fichero común se mantiene para ambas operaciones .

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.

El desbordamiento de las funciones () y desbordamiento () / sync () realizar la E / S entre el archivo y las áreas get y put de la memoria intermedia. Cuando CharT no es char, la mayoría de las implementaciones de almacenar caracteres de varios bytes en el archivo y una faceta std::codecvt se utiliza para realizar ancho / conversión de caracteres multibyte .

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.
