bool EnlistPromotableSinglePhase(
	IPromotableSinglePhaseNotification^ promotableSinglePhaseNotification


Type: System.Transactions::IPromotableSinglePhaseNotification^

A IPromotableSinglePhaseNotification interface implemented by the participant.

Return Value

Type: System::Boolean

A SinglePhaseEnlistment interface implementation that describes the enlistment.

Enlistments in a transaction are volatile; that is, they do not survive the failure of the participant. In addition, this method only suggests the transaction manager to escalate control, but the escalation itself is not guaranteed. If escalation fails, the user is not notified and the transaction is rolled back.

The parameter promotableSinglePhaseNotification is used to communicate to the transaction manager the outcome of attempting to commit the resource manager's internal transaction. If inconsistent data is reported, the transaction manager throws an exception. If an InDoubt outcome is reported, the transaction manager looks for the outcome notification in its own internal enlistment and ignores the reported response.

For more information on enlistments and escalation of a transaction, please see . For more information on PSPE, see .653d51d1-b4bf-4e34-9a6f-aec073f0f5bb5b87ae58-8ccf-4b9b-9715-41e4aade89b7

Note   This method uses LinkDemand to prevent it from being called from untrusted code; however, only the immediate caller is required to possess the FullTrust permission set.
