    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.
