All I want to do is detect that the system is shutting down in my driver
so I can write something (save settings) to the registry. I have tried
these methods:
Assumed XP unloaded my driver before shutting down… I assumed
wrong.
Looked for a system power state change via IRP_MN_SET_POWER with
PowerType==SystemPowerState and PowerState==PowerSystemShutdown as the
data. Didn’t seem to get the Irp.
Tried to register for shutdown notification with
IoRegisterShutdownNotification()… Couldn’t link. Still dont know what
lib it is in. Also, does not appear to be compatible with Win98.

You will go insane if you try to do something for NT & 98. 2K & XP have Power state change callback you can register for.

I listed that as option number 3, like I said, I cant get it to link and it
does not appear to be compatible with the 98 ddk.

I did read somewhere about register for a callback. Is that the only
way? There is no 98 solution?

I am not sure why #2 & #3 are not working for you. I do get power state changes and callbacks. The thing you have be aware of is that even if you get power state changes indicating a shutdown, the registry may not be in a state where you can write to it.
I link IoRegisterShutdownNotification just fine in Win98. Just make sure define it properly like

Wow am I a dummy. Can someone give me a virtual boot to the head
please. Since I don’t include ntddk.h ( i use wdm.h), I had to forward
declare the register function myself. However, I forgot to use extern “C”
in front of it… Doh! As far as option 2, I am going to try a
different machine as my laptop (never buy an HP laptop, they blow) has
been exhibiting a couple other problems… like not actually putting my
usb device into D3 on idle detect (works just fine on other computers).
Thanks,
Justin
