How Can I handle read and write request

NTFSD
1

Good morning
My first question is to read a file’s header 20 bytes when I
process IRP_MJ_CREATE in my filter , but I often get some
blue screens, could anyone tell me why and how to handle it?

My second question is how to get user buffer when I process
IRP_MJ_READ in Notepad?

Any information is helpful.
Thanks

Read the OSR FAQ to begin. It is possible to do this and I have done it
before. I can think of several ways to accomplish, but you need to read the
NT File Systems book to obtain some basic information about your task.
