#include <db.h> 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 BLOB. You open a BLOB 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.
