std::basic_filebuf是std::basic_streambuf，其相关联的字符序列是一个文件。两者的输入序列和输出序列具有相同的文件相关联，和一个联合的文件中的位置被保持为两个操作.

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.

函数下溢（）和溢出（）/同步（）执行实际的I / O之间的文件和get和put的缓冲。 CharT是不char时，大多数实现存储在文件中的多字节字符和一个std::codecvt方面使用，执行宽/多字节字符转换.

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.
