ITransaction::Abort

Aborts a transaction.

HRESULT Abort(
   BOID *   pboidReason,
   BOOL   fRetaining,
   BOOL   fAsync);

Parameters

pboidReason

[in]
A pointer to a BOID that indicates why the transaction is being aborted. If this is a null pointer, no reason is provided.

fRetaining

[in]
Whether the abort is retaining or nonretaining.

fAsync

[in]
When fAsync is TRUE, an asynchronous abort is performed and the caller must use ITransactionOutcomeEvents to learn the outcome of the transaction.

Return Code

S_OK
The transaction was successfully aborted.

XACT_S_ABORTING
An abort operation was already in progress. This call was ignored.

XACT_S_ASYNC
An asynchronous abort was specified. The abort operation has begun but its outcome is not yet known. When the transaction is complete, notification will be sent by ITransactionOutcomeEvents.

E_FAIL
The transaction failed to abort for an unspecified reason.

E_UNEXPECTED
An unexpected error occurred. The transaction status is unknown.

XACT_E_ALREADYINPROGRESS
A commit operation was already in progress. This call was ignored.

XACT_E_CANTRETAIN
A retaining abort is not supported or a new unit of work could not be created. The abort succeeded and the session is in autocommit mode.

XACT_E_CONNECTION_DOWN
The connection to the transaction manager failed. The transaction state is unknown.

XACT_E_INDOUBT
The transaction status is in doubt. A communication failure occurred or a transaction manager or resource manager has failed.

XACT_E_NOTRANSACTION
The transaction cannot be aborted because it already had been implicitly or explicitly committed or aborted. This call was ignored.

XACT_E_NOTSUPPORTED
fAsync was TRUE on input and asynchronous abort operations are not supported.

The following table shows how the values of fRetaining and DBPROP_ABORTPRESERVE affect the rowset state and transaction mode.
