The corresponding code is:


ULONG
NTAPI
MiQueryAddressState(IN PVOID Va,
                    IN PMMVAD Vad,
                    IN PEPROCESS TargetProcess,
                    OUT PULONG ReturnedProtect,
                    OUT PVOID *NextVa)
{
...
                /* Check if this is an image-backed VAD */
                if ((TempPte.u.Soft.Valid == 0) &&
                    (TempPte.u.Soft.Prototype == 1) &&
                    (Vad->u.VadFlags.PrivateMemory == 0) &&
                    (Vad->ControlArea))
                {
                    DPRINT1("Not supported\n");
                    ASSERT(FALSE);
