如何獲取C++接口VMT的地址
[英]How to get address of C++ interface VMT
問題描述
語境：
我正在嘗試使用 Delphi 應用程序中的一些 COM 接口（Direct2D 1.1）。 為此，我必須將接口移植到 Delphi。 我已經這樣做了，但是其中一個接口有問題：我調用的方法不正確。 我通過在 C++ 和 Delphi 中編寫完全相同的代碼來驗證這一點。 在調試器下運行兩者，我看到Delphi調用的代碼與C++調用的代碼不一樣。 所以我在移植那個接口時犯了一個錯誤。
為了找出我的錯誤在哪里，我想轉儲所有方法指針以比較 C++ 和 Delphi 顯示的地址。 它們應該與指向相同的 DLL 相同。
我不知道如何掌握VMT！ 我已閱讀此內容，但不適用於我的情況：.h 文件不包含 C 等效項。
我正在尋找類似於我用來檢查結構的 offsetof() 和 sizeof() 的東西。 以及獲取給定接口方法地址的東西。
任何幫助表示贊賞。 PS：我希望我的英語是可以理解的。

我找到了解決方案，所以我將回答我自己的問題：
下面是將指針為變量“Screen”的接口的 VMT 加載到指針數組 VMT 中所需的代碼。 代碼假設有 93 種方法（實際上是這樣）。 我還不知道如何獲取給定接口中的方法計數以完全自動化該過程。
UINT_PTR* Ptr1 = reinterpret_cast<UINT_PTR*>(Screen);
UINT_PTR* Ptr2 = reinterpret_cast<UINT_PTR*>(*Ptr1);
UINT_PTR* VMT[92];
for (UINT I = 0; I < ARRAYSIZE(VMT); I++) {
VMT[I] = reinterpret_cast<UINT_PTR*>(*Ptr2);
Ptr2++;
}
我通過使用調試器並加載 Windows 符號來驗證此代碼是否正常。 這在 VMT 中給出以下結果：

您可以看到前 3 個條目是 QueryInterface、AddRef 和 Release 方法，這是所有接口在其 VMT 中所具有的。
