int
DB_SEQUENCE->close(DB_SEQUENCE *seq, u_int32_t flags);  

The DB_SEQUENCE->close() method closes the sequence handle. Any unused cached values are lost.

The DB_SEQUENCE handle may not be accessed again after DB_SEQUENCE->close() is called, regardless of its return.

The DB_SEQUENCE->close() method returns a non-zero error value on failure and 0 on success.
