Mirror Driver - *tracking changes

NTDEV
1

Hi.
I wrote mirror driver, and I have problem with tracking.

I wrote functions which save changes of rectangle and path. And
I don’t understand how to track all changes for example in DrvBitBlt function:
Do I need to save just prclDst variable or I need to save also for example pco and others to calculate area which was modified?
Could someone can answer please.

Figure it out! You have to figure this out! It’s not hard, and you
have all the information you need, but it is simply UNREASONABLE for you
to ask us to write this driver for you, piece by piece, 5 lines at a
time, via e-mail, for free.
