FileStream操作类
The fileStream.rdbuf() function returns a pointer to the underlying streambuf object that is associated with the file stream object. The streambuf object provides an interface to the actual input/output device used by the file stream object. This function can be used to access the low-level I/O functionality of the file stream object, for example, to read or write binary data directly from/to the file.
