请问ExitWindowsEx如何用阿？

Question

vc 6.0 中使用ExitWindowsEx注销操作直接可以成功。但关机和重起都失败了。
关机时是不是还要设置process特权阿？
请大虾指教。

void ShutDown(void)
{
 OSVERSIONINFO osv;
 osv.dwOSVersionInfoSize=sizeof OSVERSIONINFO;
 GetVersionEx(&osv);
 if(osv.dwPlatformId==VER_PLATFORM_WIN32_NT)
 {
  HANDLE hProcess,hToken;
  TOKEN_PRIVILEGES Privileges;
  LUID luid;
  hProcess=GetCurrentProcess();
  OpenProcessToken(hProcess,TOKEN_ADJUST_PRIVILEGES,&hToken);
  Privileges.PrivilegeCount=1;
  LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,&luid);
  Privileges.Privileges[0].Luid=luid;
  Privileges.Privileges[0].Attributes=SE_PRIVILEGE_ENABLED;
  AdjustTokenPrivileges(hToken,FALSE,&Privileges,NULL,NULL,NULL);
 }
 ExitWindowsEx(EWX_POWEROFF,0);
}

void ShutDown()
{
OSVERSIONINFO osversioninfo;
osversioninfo.dwOSVersionInfoSize=sizeof(OSVERSIONINFO);
GetVersionEx(&osversioninfo);
int nID=osversioninfo.dwPlatformId;
if(nID<=1)
goto Exit;
HANDLE Handle;
Handle=::GetCurrentProcess();
HANDLE HandleProcess;
OpenProcessToken(Handle,TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,&HandleProcess);
LUID tmpLuid;
LookupPrivilegeValue(NULL,"SeShutdownPrivilege",&tmpLuid);
TOKEN_PRIVILEGES tkpNew;
TOKEN_PRIVILEGES tkpPrevious;
tkpNew.PrivilegeCount=1;
tkpNew.Privileges[0].Attributes=SE_PRIVILEGE_ENABLED;
tkpNew.Privileges[0].Luid=tmpLuid;
DWORD lbufferNeeded;
AdjustTokenPrivileges(HandleProcess,false,&tkpNew,sizeof(tkpPrevious),&tkpPrevious,&lbufferNeeded);
Exit:
ExitWindowsEx(EWX_FORCE|EWX_REBOOT,0);
}
