[ros-dev] Public ddk headers vs ntoskrnl

[Timo Kreuzer]

Hi,

I am currently having a small problem on the x64 branch, maybe someone
can help me.

In wdm.h there's the following declarations:

#if defined (_WIN64)
#if defined(_NTDRIVER_) || defined(_NTDDK) || defined(_NTIFS_) || \
    defined(_NTHAL_) || defined(_NTOSP_)
NTKRNLAPI
USHORT
ExQueryDepthSList(IN PSLIST_HEADER Listhead);
#else
FORCEINLINE
USHORT
ExQueryDepthSList(IN PSLIST_HEADER Listhead)
{
    return (USHORT)(ListHead->Alignment & 0xffff);
}
#endif
#else
#define ExQueryDepthSList(listhead) (listhead)->Depth
#endif

So when compiling ntoskrnl, ExQueryDepthSList is not inlined. Later in
wdm.h (currently in our winddk.h, but to be moved to wdm.h)
ExQueryDepthSList is used in ExFreeToNPagedLookasideList inline function.

But I want ExQueryDepthSList to be inlined from within ntoskrnl. The
question is how can I achieve this?
If I #define it to be inline in ntoskrnl's private headers, it will not
affect ExFreeToNPagedLookasideList.
When I declare it as an inline function after the header is included, I
get a warning that it was declared inline after being used and that a
static declaration follows a non-static. (Does anyone know hoe to
disable these stupid warnings?)
Declaring it inline before including wdm.h doesn't work, as the needed
declaration for SLIST_HEADER is missing.

Anyone got any other idea? I'd like to avoid hacking our public headers,
to keep them as compatible to ms headers as possible.

Regards,
Timo
