Syntax
NTSTATUS TmPrePrepareComplete(
[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
TmPrePrepareComplete returns STATUS_SUCCESS if the operation succeeds. Otherwise, this routine might return one of the following values:
| Return code | Description |
|---|---|
|
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.
Remarks
The TmPrePrepareComplete routine is a pointer-based version of the ZwPrePrepareComplete routine.
