[Microsoft strongly recommends developers utilize alternative means to achieve your application’s needs. Many scenarios that TxF was developed for can be achieved through simpler and more readily available techniques. Furthermore, TxF may not be available in future versions of Microsoft Windows.

The FSCTL_TXFS_SAVEPOINT_INFORMATION structure specifies the action to perform, and on which transaction.
KtmTransactionHandle to the transaction on which to perform the savepoint operation.
ActionCodeSpecifies the savepoint action to perform. Valid values are:
| Value | Meaning |
|---|---|
| TXFS_SAVEPOINT_SET 1 (0x1) |
Creates a new savepoint. |
| TXFS_SAVEPOINT_ROLLBACK 2 (0x2) |
Rolls back to the savepoint specified by the SavepointId member. |
| TXFS_SAVEPOINT_CLEAR 4 (0x4) |
Clears the most recently set savepoint for the specified transaction. |
| TXFS_SAVEPOINT_CLEAR_ALL 16 (0x10) |
Clears all savepoints for the transaction. |
SavepointIdIf ActionCode is TXFS_SAVEPOINT_SET, on output, returns the newly-created savepoint ID.
If ActionCode is TXFS_ROLLBACK_TO_SAVEPOINT, on input, specifies the savepoint ID to roll back to. Remains unchanged on output.
If ActionCode is TXFS_SAVEPOINT_CLEAR or TXFS_SAVEPOINT_CLEAR_ALL, this member is not used; therefore, on input, specify NULL.
