ntddk.h and wdm.h

NTDEV
1

I used to include <wdm.h> in my driver. Now I need to include some function
that is included only in <ntddk.h>. It’s not possible to include both, I
therefore only include <ntddk.h>, which happens to be also what I have read
in the archive, under this thread:
http://www.osronline.com/lists_archive/ntdev/thread8453.html

The problem I’m facing now is that I also need to include <stdunk.h>, which
in turn includes <wdm.h>. Multiple definitions!! Bummer.

How should I circumvent this? I hope there is something else to do, other
than to copy-paste the function prototypes in my project.

A quick and dirty way is:

#define WDMDDK

before including stdunk.h. It should work if wdm.h is really a subset of
ntddk.h. Note I know nothing about stdunk.h and its needs.

Try creating a dummy blank wdm.h and make sure it’s installed earlier in
the include path,
or temporarily rename the real wdm.h.

If you are using c++ you could use a namespace to avoid multiple
definitions:

#include <ntddk.h>

namespace WDM
{
#include <wdm.h>
};

This will still give you many macro redefinition errors as macros are not
considered in the namespace. I have used this successfully with ntddk.h and
ntifs.h

You could try to isolate the functions using the extra part of ntddk.h and
stdunk.h from each other, encapsulate them into separated C resp. C++
modules and include only one of them - ntddk.h or stdunk.h - in each of
both. However exported interfaces of both modules (and rest of driver) must
depend only from wdm.h to realize this.

Thank you guys for your suggestions. I think the “#define WDMDDK” trick
is the cleanest one. It simply fools wdm.h into thinking it’s already been
included. Works for me.
