Hi,

I’m new to FSD filter and working on some filter driver code. How can
I tell if the driver is FSD filter? Is IoRegisterFsRegistrationChange
call an indication? Thanks a lot.

This is a weird question. You are the developer, you must know
what your source is for. If you cannot tell this,
how can you work on it ?

A driver code may be recognized by the “DriverEntry” function
A DLL code may be recognized by the “DllMain”
An EXE code may be recognized by the “WinMain” or “main”

Ok, basically, a FSD filter (“File System Driver Filter”)
may be recognized because it “filters file system”.
“Filters file system” means that is is a driver,
which is attached to one or more file system drivers.
IoRegisterFsRegistrationChange may or must not be there.

Yes, most properly written FSFs do this. Note that minfilters based on
FtlMgr do not - FltMgr have already did it for them.
