 //! responsible for creating or closing the file. Users of this class must

 //! this class may be used to write to file handles not associated with
 //! filesystem-based files, although special attention should be paid to the
 //! Seek() method, which may not function on file handles that do not refer to
 //! disk-based files.
 //!
 //! This class is expected to be used when other code is responsible for
 //! creating files and already provides file handles.
