I want to know if WDK support “new” and “delete” operator?
I found my driver code with “new” operator cannot be compiled successfully.
but “new” can be used in driverstudio tool? why?
I found a article wrote by Microsoft, which said MS don’t advise driver engineer use C++ to write driver,especially the “new” operator.
thanks
Denny
You need to provide your own global new and delete (or provide them as static operators on your class(es))

Did you “read” and understand the article from Microsoft? Was it:
http://www.microsoft.com/whdc/driver/kernel/KMcode.mspx ?
Answers for these two questions should be ‘yes’. If not, do it.
Are you fluent in C++ in user mode? Are you addicted to C++ exception
handling in your user mode code?
Answers for these two questions should be ‘no’ as it will be a major effort
on your part to retrain your mind to only think of kernel safe C++
constructs. C++ exceptions will NOT work in the kernel as only SEH is
supported.
Have you ever used ‘placement new’ constructs? Have you ever provided your
own ‘new’ operator in a class to override the standard C++ version available
in the RTL for user mode?
Using the words ‘driverstudio tool’ is a great way to prove your
inexperience, though it can be used to learn if you don’t think it really
works without a lot of effort to fix the bugs.

Using C++ in the kernel is something that only VERY experienced driver
programmers should attempt. If you didn’t immediately understand Doron’s
answer and how to do what he said, you should not use C++ in a driver.

The include file <kcom.h> in the DDK includes kernel-friendly definitions
for operator new and operator delete. Even if you don’t use the rest of
the file, you can copy that section to your own include file.

Write your own “operator new” routine, and note that C++ exceptions are not supported in the kernel, so, you will need to check each “new” call for a NULL return manually.
BTW - DriverStudio is a heap of bugs. The sooner you will abandon this product, the better. Use KMDF instead.

That’s probably a language issue for the OP rather than a failure of
understanding.

No matter how you look at it, using a framework that had been officially retired 3 years ago , indeed, suggests lack of experience, rather than anything else - I fully agree with David here…

That’s because DriverStudio defined the class libraires and header files
needed to use classes in the kernel. However, DriverStudio, which is dead
and buried, produces a piece of crap that will fail PreFast and Driver
Verifier, unless you FIX the DriverStudio files yourself.

And I suspect you do not want to waste the time to do that, since the last
time I looked DriverStudio was producing over 1000 significant errors by
PreFast (and that was with a PreFast before the full annotations were
supported)! It really is a piece of crap.

Hmm. I use Visual Studio v. 6 for all my development. So what does that make
me?

If we assume that your current work is not limited to the UM development (I am sure it is not), objectively, you just cannot use it for ALL your development - even if you generate your binaries with VC, rather than WDK compiler, you still need WDK headers and libraries. If you mean using Visual Studio v. 6 for writing and managing code…well, I don’t know about other posters, but I don’t see anything particularly wrong with it - after all, this is exactly how I was writing Windows drivers myself. Again, I don’t know about other posters, but my only requirement to code editor is highlighting. For example, my current tool of choice is Gedit, which is nothing more than just a Linux equivalent of Notepad - it does highlighting job fairly well, and this is the only thing I need.
However, we are speaking about totally different thing here - we are speaking about using a_framework_, i.e a set of classes, headers and libraries…

Every time DB says DriverStudio has 1,000 errors in PREfast, you have to take a drink.
One drink per bug or one drink per mention ?

Actually it is a lot more than 1000, I had a customer ask me to analyze why
they were crashing so often and the result of running things like PreFast
was their code was good, and Driver Studio was shit.

thank you everyone all your response.

Generally, the only type of driver you may use c++ to write is the AVStream
Driver, the driver that interacts with MS Kernel Streaming Framework.
