如何查询正在运行的进程的登录类型？

Question

我希望至少区分我的软件作为批处理作业（LOGON32_LOGON_BATCH）以交互方式运行（LOGON32_LOGON_INTERACTIVE）时运行的情况。

HANDLE hToken; 
// Open the current process's token 
if (OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY, &hToken)) 
{ 
    // Get the token statistics, which include the logon session id 
    TOKEN_STATISTICS stats; 
    DWORD length; 
    if (GetTokenInformation(hToken, TokenStatistics, &stats, sizeof(stats), &length)) 
    { 
     // Get data about the logon session, which includes the logon type 
     PSECURITY_LOGON_SESSION_DATA pData; 
     if (LsaGetLogonSessionData(&stats.AuthenticationId, &pData) == 0) 
     { 
      // From SECURITY_LOGON_TYPE enumeration 
      switch (pData->LogonType) 
      { 
      case Interactive: 
       wprintf(L"Interactive\n"); 
       break; 
      case Batch: 
       wprintf(L"Batch\n"); 
       break; 
      default: 
       wprintf(L"Other: %i\n", pData->LogonType); 
       break; 
      } 
      LsaFreeReturnBuffer(pData); 
     } 
    } 
    CloseHandle(hToken); 
}
