The TmIsTransactionActive routine indicates whether a specified transaction is in its active state.
Syntax
BOOLEAN TmIsTransactionActive(
[in] PKTRANSACTION Transaction
);
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.
Return value
TmIsTransactionActive returns TRUE if the specified transaction is in its active state. Otherwise, the routine returns FALSE.
Remarks
When a transaction is created, it enters its active state and remains in that state until the pre-prepare/prepare/commit sequence begins.
For more information about TmIsTransactionActive, and for information about when to use KTM's TmXxx routines instead of ZwXxx routines, see Using TmXxx Routines.
