TmPrePrepareComplete function (wdm.h)

The TmPrePrepareComplete routine notifies KTM that the calling resource manager has finished preliminary preparation of a transaction's data.

Syntax

NTSTATUS TmPrePrepareComplete(
  [in] PKENLISTMENT   Enlistment,
  [in] PLARGE_INTEGER TmVirtualClock
);

[in] Enlistment

A pointer to an enlistment object. Your component can receive this pointer as input to a ResourceManagerNotification callback routine. Alternatively, your component can call ObReferenceObjectByHandle and supply the object handle that a previous call to ZwCreateEnlistment, TmCreateEnlistment, or ZwOpenEnlistment provided.

[in] TmVirtualClock

A pointer to a virtual clock value. This parameter is optional and can be NULL.

TmPrePrepareComplete returns STATUS_SUCCESS if the operation succeeds. Otherwise, this routine might return one of the following values:

Return code	Description
STATUS_TRANSACTION_NOT_REQUESTED	The transaction or its enlistment is not in the correct state. For example, KTM did not send a TRANSACTION_NOTIFY_PREPARE notification.

The routine might return other NTSTATUS values.

The TmPrePrepareComplete routine is a pointer-based version of the ZwPrePrepareComplete routine.
