VISTA Transactions and IO_DRIVER_CREATE_CONTEXT

NTFSD
1

Hi, all
I’m porting legacy filesystem driver into Vista’s TxF enviroment. My
question is: is there any way how to obtain transaction ID in
IRP_MJ_CREATE before I’ll send it down the stack to NTFS.SYS ? Or simply
said, where does the TxnParameters from IO_DRIVER_CREATE_CONTEXT during
IoCreateFileEx end up in IRP_MJ_CREATE ?

thanks for any hint.

Hi Martin

Have a look at filespy in WDK 6000 or later; I believe the answer and some
more is there for you :slight_smile:

Cheers

Hi and thanks for answer,
but by IoGetTransactionParameterBlock I’m able to find
TRANSACTION_PARAMETER_BLOCK on post create, is there any way how to
detect on precreate that incoming IRP_MJ_CREATE should be bound to a
transaction ?.

Regards
Martin
