NTSTATUS 转到 Win32 error ？？

#include <windows.h>
#include <stdio.h>
//#include <Winternl.h>
//#include <LMACCESS.h>// typedef LONG NTSTATUS, *PNTSTATUS;
#include <NtSecApi.h>// typedef LONG NTSTATUS, *PNTSTATUS;

// 下面函数是某英文网站看到的
/*
 * This is an alternative to the RtlNtStatusToDosError()
 * function in ntdll.dll. It uses the GetOverlappedResult()
 * function in kernel32.dll to do the conversion.
 */
DWORD ConvertNtStatusToWin32Error(LONG ntstatus)
{
    DWORD oldError;
    DWORD result;
    DWORD br;
    OVERLAPPED o;

    o.Internal = ntstatus;
    o.InternalHigh = 0;
    o.Offset = 0;
    o.OffsetHigh = 0;
    o.hEvent = 0;
    oldError = GetLastError();
    GetOverlappedResult(NULL, &o, &br, FALSE);
    result = GetLastError();
    SetLastError(oldError);
    return result;
}

void main()

    printf("%d\n", dw);

// *** ***

顺路看到几个宏，记下来：

1. MAKE_HRESULT(sev, fac, code): 将 severity、facility、code 合并为 HRESULT  
2. HRESULT_CODE(hr): 取得 HRESULT 的 code 部分  
3. HRESULT_FACILITY(hr): 取得 HRESULT 的 facility 部分  
4. HRESULT_SEVERITY(hr): 取得 HRESULT 的 severity 位  
5.   
6. HRESULT_FROM_NT(nt_stat): 从 NTSTATUS 变换到 HRESULT  
7. HRESULT_FROM_WIN32(win_err): 从 Win32 状态码变换到 HRESULT  
8.   
9. SUCCEEDED(hr): HRESULT 是否表示成功  
10. FAILED(hr): HRESULT 是否表示失败  
11. IS_ERROR(hr): HRESULT 是否表示一个错误
