classes in a driver

NTFSD
1

Hi.
I am implementing a driver and I opted for the object oriented desing. So I am implementing classes in my driver.
By now I am just using my classes without dynamic memory allocation. Because I would have to redefine new and delete operators. So I have to remove the virtual destructors of my classes.

I tried to redefine delete operator like this:
void operator delete(void * p);

I got this error:

error C2373: ‘delete’ : redefinition; different type modifiers

How should I redefine operator delete.

I tried to redefine delete operator like this:
void operator delete(void * p, unsigned int size);

And I got this error:

error LNK2001: unresolved external symbol “void __cdecl operator delete(void *)” (??xxxxx@YAXPAX@Z)

These two links should give you enough information.

DDK uses __stdcall as default calling convention. Specify __cdecl
explicitely to make linker happy.

Now I get it. Thanks.
Well, anyway I used the files I downloaded from the links Rob gave me and
that was what I needed.
Thanks, Rob.
