int
DB_STREAM->close(DB_STREAM *dbs, u_int32_t flags);  

The DB_STREAM->close() method flushes any unwritten data to disk, frees allocated resources, and closes the underlying file which contains the external file. You open an external file stream using DBC->db_stream() .

Once this method is called, the stream can not be used again even if this method returns an error.

Unless otherwise specified, the DB_STREAM->close() method returns a non-zero error value on failure and 0 on success.
