DbTxn::abort

#include <db_cxx.h> int DbTxn::abort(); Description The DbTxn::abort method causes an abnormal termination of the transaction. The log is played backwards and any necessary recovery operations are initiated through the recover function specified to DbEnv::open. After the log processing is completed, all locks held by the transaction are released. As is the case for DbTxn::commit, applications that require strict two-phase locking should not explicitly release any locks. In the case of nested transactions, aborting a parent transaction causes all children (unresolved or not) of the parent transaction to be aborted. Once the DbTxn::abort method returns, 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. Errors The DbTxn::abort method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbTxn::abort method may fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
