c++ - 如何在Windows 2016 Server版本1607中访问SetThreadDescription()

Question

如果我只是从WinAPI调用SetThreadDescription()，它将在Windows 10版本2004上运行。但是，在Windows 2016 Server 1607上，它将生成以下消息框:

The procedure entry point SetThreadDescription could not be located in the dynamic link library

消息中将显示我的可执行程序的路径。

根据this article:

SetThreadDescription is only available by Run Time Dynamic Linking on Windows Server 2016, 1607.

所以我尝试了动态链接，如下所示:

typedef HRESULT (WINAPI *TSetThreadDescription)(HANDLE, PCWSTR);

namespace {
  TSetThreadDescription gpSetThreadDescription = nullptr;
}

void Initialize() {
  HMODULE hKernel32 = GetModuleHandleA("Kernel32.dll");
  if (hKernel32 == nullptr) {
    cerr << "FATAL: failed to get kernel32.dll module handle, error: " << GetLastError() << endl;
    quick_exit(5);
  }
  gpSetThreadDescription = reinterpret_cast<TSetThreadDescription>(
    GetProcAddress(hKernel32, "SetThreadDescription"));
  if (gpSetThreadDescription == nullptr) {
    cerr << "FATAL: failed to get SetThreadDescription() address, error: " << GetLastError() << endl;
    quick_exit(6);
  }
}

此代码也可以在Windows 10上使用。但是，在Windows Server 2016上出现错误127(“找不到指定的过程”)。

我在运行时动态链接上做错了什么？

显然，尽管MSDN说“DLL:Kernel32.dll”，但该函数实际上在KernelBase.DLL中，因此在更改为以下内容后，我已解决了该问题:

HMODULE hKernelBase = GetModuleHandleA("KernelBase.dll");
