堆栈溢出，当我使用 Detours 拦截 CreateFileW

Question

我想拦截 win32 api CreateFileW，但遇到错误“堆栈溢出”。我不知道发生了什么，有人可以帮助我吗？

错误：在 detoursExample.exe 中的 0x00007FFA76204170 (KernelBase.dll) 抛出异常：0xC00000FD：堆栈溢出（参数：0x0000000000000001、0x00000094A6A03FF0）。 detoursExample.exe 中 0x00007FFA76204170 (KernelBase.dll) 的未处理异常：0xC00000FD：堆栈溢出（参数：0x0000000000000001、0x00000094A6A03FF0）。

在newCreateFile中，您需要调用oldCreateFile，而不是CreateFileW。你这样做的方式，你的钩子最终会永远调用自己。
