KTL Issues. CH 12 PG 424-426

Pavel,

I am reaching out to you because I am getting an error with the following code:

Main.cpp

include "pch.h"

include "DriverMain.h"

include "MiniFilter.h"

NTSTATUS OnCreateClose(PDEVICE_OBJECT, PIRP Irp); void UnloadFunc(PDRIVER_OBJECT DriverObject); NTSTATUS InitMiniFilter(PDRIVER_OBJECT DriverObject, PUNICODE_STRING RegistryPath);

extern "C" NTSTATUS DriverEntry(In PDRIVER_OBJECT DriverObject, In PUNICODE_STRING) { **g_State = new (PoolType::NonPaged, DRIVER_TAG) FilterState;** <- issue here

MiniFilter.h

pragma once

include <D:\Training\windowskernelprogrammingbook2e\ktl\ktl\ktl.h>

struct FilterState { FilterState(); ~FilterState();

PFLT_FILTER filter;
*********Vector<WString<PoolType::NonPaged>, PoolType::NonPaged> Files;** <- issue here
ExecutiveResource Lock;
PDRIVER_OBJECT DriverObject;

};

It appears that the overloading functions are generating errors that I am giving the functions the wrong inputs when I try to use them: For WString it's saying I am giving it too few arguments.

For new it says no instance of overloaded function matches the argument list unsigned long long, PoolType.

I was able to overcome these issues by calling functions like so: Vector<WString<PoolType::NonPaged, DRIVER_TAG>, PoolType::NonPaged, DRIVER_TAG> Files; g_State = new (PoolType::NonPaged, DRIVER_TAG) FilterState;

However, now when i try to follow along with the book I have a new problem entirely!

in MiniFilter.h UNICODE_STRING path; auto status = FLT_PREOP_SUCCESS_WITH_CALLBACK; { SharedLocker locker(g_State->Lock); for (auto& name : g_State->Files) { *****name.GetUnicodeString(path);** <- issue here } }

no instance of overloaded function "BasicString<T, Pool, Tag>::GetUnicodeString [with T=wchar_t, Pool=PoolType::NonPaged, Tag=69UL]" matches the argument list and object (the object has type qualifiers that prevent a match) DirectoryHider DriverProjects\DirectoryHider\DirectoryHider\MiniFilter.cpp

Indeed, the correct way to work is to add your Tag as part of the field. I'll check why GetUnicodeString fails to compile. I did some improvements to KTL that I may have not pushed yet.

Pushed updates to KTL. See if that resolves the compiler error.
