#include <db.h>int txn_abort(DB_TXN *tid);
The txn_abort function 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 txn_commit, applications that require strict two-phase locking should not explicitly release any locks.
In the case of nested transactions, aborting the parent transaction causes all children of that transaction to be aborted.
The txn_abort function returns a non-zero error value on failure and 0 on success.
In addition, the txn_abort function may fail and return a non-zero error for the following conditions:
In addition, the txn_abort function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
