#include <db.h> int DB_SEQUENCE->remove(DB_SEQUENCE *seq, DB_TXN *txnid, u_int32_t flags);
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.
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.
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.
The DB_SEQUENCE->remove()
method may fail and return one of the following non-zero errors:
