Description

The TmGetTransactionId routine retrieves a transaction object's unit of work (UOW) identifier.

TransactionId [out]

A pointer to a location that receives the transaction object's UOW identifier.

Remarks

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