Berkeley DB: DbTxn::abort
DbTxn::abort

#include <db_cxx.h>
int
DbTxn::abort();
Description: DbTxn::abort
The DbTxn::abort method causes an abnormal termination of the transaction.
The log is played backward, and any necessary undo operations are done
through the tx_recover function specified to
DbEnv::set_app_dispatch. Before DbTxn::abort returns, any
locks held by the transaction will have been released.
In the case of nested transactions, aborting a parent transaction causes
all children (unresolved or not) of the parent transaction to be aborted.
All cursors opened within the transaction must be closed before the
transaction is aborted.
After DbTxn::abort has been called, regardless of its return, the
DbTxn handle may not be accessed again.
The DbTxn::abort 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.
