DB_SEQUENCE->remove()
#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.
Parameters
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.
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_NOSYNCIf 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.
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.
