Is C++ allowed in File system Filter drivers?

Hi,

Could we use C++ classes inside file system filter drivers on Windows 2000
and XP?

Any information is helpful.

Thanks,
Kedar.

Before this goes into a month long thread of people on both sides of the
line, you should definitely look through the archives. For anyone who has
been on this list for awhile knows that this is likely one of the most
debated subject, aside from the benefits of OS patching.

Yes you can use it for sure. DriverWorks from compuware provides a base
template in c++ to write a file system filter driver.

Yes :stuck_out_tongue:
Frankly, I think it can lead to greater stack consumption, but I have a 6 MB C++
driver code - and I was advocating against C++ in drivers.
I suggest using NuMega’s DriverWorks for C++ support, it definitely takes care of
virtually everything you don’t want to take care of. Alternately, there are small
libraries for C++ support in drivers, with much more limited capabilities.

They have a C++ template specifically for an FSF now?

Where is that? I see no specific example or anything in the DriverWizard that makes an FSF driver. Of course you can make a barebone driver and add FSF calls, but… that’s no more specific that C++ support.
NuMega planned to add a wizard specifically for FSF creation, I guess they decided not to due to Mini-filters.
