Hi

There is a way to queue a APC from a NT driver to be handled by a user level
process (like vxds can do with _VWIN32_QueueUserApc...)

Thank you

Note: this will require the kernel memory to be allocated for the KAPC
structure, and the memory must be properly freed in all paths.

I think it is a better idea to pend the IRP in the kernel module, and complete
it when it will be needed.

There is no help topic about these functions on the 2k3, XP DDK help file !

They are not documented.

Those are either part of the IFS, or undocumented commands.

Which means you ain't supposed to be using them. If you do, and they change
in the next release or service pack ... to bad.

I will give up using APC. I will use kernel events (already using) to notify
a user mode app.

Thanks for all that have contributed !

If you are going to be changing things (which your question certaining
indicated) then why don't you take Max's suggestion of use an IRP and pend
it till the event. This is cleaner and simpler (and therefore can be safer)
than using an event.

Sometimes shared event is the only option since not every kind of driver has
a dispatch routine nor has access to IRP such as the stupid video miniport
driver.
