Failing the last write

NTFSD
1

Hello,

i have a scenerio where i would like to catch the last write operation to a file .

For example if the user mode programs creates a new file and writes data to it, i would like to return an error/success to the program based on some logic. And the logic can only be detrmined once i see all teh writes to the block.

Any thought how can this achieved?

Thank you,
OCN

If you need to fail writes - fail CREATE with write in DesiredAccess.
Failing writes themselves is not an option.
