ZwCreateFile fail with error STATUS_TOO_LATE

NTDEV
1

Hi,
I’m writing a miniport NDIS driver and I need to update a file during computer restart.
The problem is that in my shutdown handler when I’m trying to access the file I get error STATUS_TOO_LATE when I call ZwCreateFile.
According to header file this error code mean that “A write operation was attempted to a volume after it was dismounted”
is there an earlier callback that I can use that happen during computer restart?
is there a way to ensure that the filesystem will go down after my Miniport driver will unload?
This is a driver for a wifi card.

Thanks,
Sagi

Register a power ex notification callback. It will be called right before power down starts.

Hi,

Thanks for the reply.
Do you mean to use the PoRegisterPowerSettingCallback API?
Can it be used from an NDIS Miniport driver?

Thanks,
