#include <db_cxx.h> int DbStream::close(u_int32_t flags);
         The DbStream::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
         DbStream::close() 
            
            
                method either returns a non-zero error value or throws an
                exception that encapsulates a non-zero error value on
                failure, and returns 0 on success.
