小编NUL*_*ULL的帖子

我试图在Windows 7上使用GCC从MSDN编译一些示例代码(请忽略使用goto和可怕的格式化;它不是我的代码):

#include <stdio.h>
#include <windows.h>

typedef struct _TOKEN_ELEVATION {
    DWORD TokenIsElevated;
} TOKEN_ELEVATION, *PTOKEN_ELEVATION;

BOOL IsProcessElevated()
{
BOOL fIsElevated = FALSE;
DWORD dwError = ERROR_SUCCESS;
HANDLE hToken = NULL;

if (!OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY, &hToken))
{
    dwError = GetLastError();
    goto Cleanup;
}

TOKEN_ELEVATION elevation;
DWORD dwSize;
if (!GetTokenInformation(hToken, TokenElevation, &elevation,
    sizeof(elevation), &dwSize))
{
    dwError = GetLastError();
    goto Cleanup;
}
fIsElevated = elevation.TokenIsElevated;

Cleanup:
if (hToken)
{
    CloseHandle(hToken);
    hToken = NULL;
}
if (ERROR_SUCCESS != dwError)
{
    throw dwError;
}
return fIsElevated; …
