TmRollbackTransaction function (wdm.h)
The TmRollbackTransaction routine initiates a rollback operation for a specified transaction.
Syntax
NTSTATUS TmRollbackTransaction(
[in] PKTRANSACTION Transaction,
[in] BOOLEAN Wait
);
Parameters
[in] Transaction
A pointer to a transaction object. To obtain this pointer, your component must call ObReferenceObjectByHandle and supply the object handle that a previous call to ZwCreateTransaction or ZwOpenTransaction provided.
[in] Wait
A Boolean value that the caller sets to TRUE for synchronous operation or FALSE for asynchronous operation. If this parameter is set to TRUE, the call does not return until the rollback operation is complete.
Return value
TmRollbackTransaction returns STATUS_SUCCESS if the operation succeeds. Otherwise, this routine might return one of the following values:
| Return code | Description |
|---|---|
|
The transaction cannot be rolled back because it has already been committed. |
|
The transaction has not been committed but its current state does not permit rollback. |
|
Rollback notifications have been queued to resource managers, and the caller specified FALSE for the Wait parameter. |
The routine might return other NTSTATUS values.
Remarks
The TmRollbackTransaction routine is a pointer-based version of the ZwRollbackTransaction routine.
