TmPrepareComplete function (wdm.h)

The TmPrepareComplete routine notifies KTM that the calling resource manager has finished preparing a transaction's data.

Syntax

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

Parameters

[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.

Return value

TmPrepareComplete 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_PREPREPARE notification.
 

The routine might return other NTSTATUS values.

Remarks

The TmPrepareComplete routine is a pointer-based version of the ZwPrepareComplete routine.

For information about when to use KTM's TmXxx routines instead of ZwXxx routines, see Using TmXxx Routines.
