An application server invokes the VoteRequestDone method to submit a vote during the prepare phase of a transaction.

Syntax

  
HRESULT VoteRequestDone(   HRESULT hr,  BOID * pboidReason);

Parameters

hr
[in] HRESULT returning a transaction voter's vote. An application sets this value to S_OK or XACT_S_NONOTIFY to approve the transaction. XACT_S_NONOTIFY specifies that the voter does not want the transaction manager to return with an outcome notification. E_FAIL specifies that the DTC should abort the transaction.

pboidReason
[in] Pointer to a BOID returning a transaction abort reason code. This value should be NULL if the voter approved the transaction. Otherwise, the voter can optionally set this value with an abort reason.

Return Values

S_OK
Success.

E_INVALIDARG
One or more parameters were invalid. For example, pboidReason must be NULL if hr == S_OK.

E_UNEXPECTED
An unexpected error occurred.

E_FAIL
VoteRequestDone was called illegally.

XACT_E_CONNECTION_DOWN
Lost connection with the transaction manager.

Remarks

The vote is submitted when the DTC sends it a vote request through the ITransactionVoterNotifyAsync2 interface. The voter can either approve the transaction or vote against it. When a voter successfully votes to abort a transaction, it is not notified of the transaction outcome.

Requirements
