    int
    DB_SEQUENCE->remove(DB_SEQUENCE *seq, DB_TXN *txnid, u_int32_t flags);

Description: DB_SEQUENCE->remove

The DB_SEQUENCE->remove method removes the sequence from the database. This method should not be called if there are other open handles on this sequence.

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

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

Parameters
flags

- The flags parameter must be set to 0 or by bitwise inclusively OR'ing together one or more of the following values:
  DB_TXN_NOSYNC
  - If the operation is implicitly transaction protected (the txnid argument is NULL but the operation occurs to a transactional database), do not synchronously flush the log when the transaction commits.

txnid

- If the operation is part of an application-specified transaction, the txnid parameter is a transaction handle returned from DB_ENV->txn_begin; if the operation is part of a Berkeley DB Concurrent Data Store group, the txnid parameter is a handle returned from DB_ENV->cdsgroup_begin; otherwise NULL. If no transaction handle is specified, but the operation occurs in a transactional database, the operation will be implicitly transaction protected.

Errors

The DB_SEQUENCE->remove method may fail and return one of the following non-zero errors:

EINVAL

- An invalid flag value or parameter was specified.
