File System Driver (Memory Mapping issues)

Hi all

I am using FSD(mini Filter) Swap Buffers to get a call of opening a msword (.doc) or a notepad(.txt) READ/WRITE. Now as these operations uses memory mapping, ie paging and non-cached requests , i am trying to figure out what procedure is used to trap these calls through my code. Some guys have suggested that you have to make use of
FileObject->SectionObjectPointers but i didnt no how to use it Plz help?

Warm Regards

Any of the suggestions are welcome

Can you refer Win NT internals by Rajeev Nagar. That explains how to use SectionObjectPointers for a memory mapped file.
