Sorry about the slight OT post.
Can anyone advise how in a Registry Callback I can determine whether the
current thread is in transaction scope and if so the transaction handle of
the current transaction scope?
Thanks
Lyndon
It looks like the answer is CmGetBoundTransaction, although (as of 5308), it
is undocumented, and returns a PVOID, with no obvious other calls prototyped
to interpret the returned opaque object.
The plugfest presentation on this a couple days ago did not give details of
calls/data structures, but it did indicate that the model is similar to the
minifilter transaction stuff.

Hi Dan
Thanks for the starter so to speak. I see this function prototype in WDK
5365 wdm.h (but not ntddk.h shame) however the function is not exported from
ntknlmp.exe (in the debug directory) for example and neither is it in the
public symbols. I also see in wdm.h a rather interesting
CmRegisterCallbackEx function prototype; this one is exported from
ntkrnlmp.exe etc. I find documentation for neither in the WDK docs.
I appreciate the Microsoft folks are very busy with Vista at the moment but
some assist here would be very much appreciated.
Regards
Lyndon

I’ll ask at plugfest today what the status of the Vista registry callbacks
are, and when they’ll be exported/documented.

Lyndon,
Check ntddk.h it now included wdm.h. This is part of the major reorg of
the includes that Microsoft has been discussing for 3 years.

Hi Lyndon,
I talked to Neal Christiansen, and it is a bug that the routine is not
exported. He is filing a bug report against it. He will also investigate
the time frame for the documentation as well, and get back to us.

Hi Lyndon,
Nothing yet. I believe Neal will reply to the list when he has answers.
