);

Parameters

[in, optional] lpTransactionAttributes

The transaction SECURITY_ATTRIBUTES (ACLs) for the TM object.

[in, optional] LogFileName

The log file stream name. If the stream does not exist in the log, it is created. To create a volatile TM, this parameter must be NULL and CreateOptions must specify TRANSACTION_MANAGER_VOLATILE, this transaction manager is considered volatile.

Any optional attributes for the new TM.

Value Meaning
TRANSACTION_MANAGER_VOLATILE
 Indicates that the TM is volatile, and does not perform recovery.

[in, optional] CommitStrength

Reserved; specify zero.

If the function succeeds, the return value is a handle to the transaction manager.

If the function fails, the return value is INVALID_HANDLE_VALUE. To get extended error information, call the GetLastError function.

Remarks

Immediately after calling this function, you must call RecoverTransactionManager.
