在NT/2000下实现关机！

众所周知，在9x下关机只要ExitWindows(0,0)就行了，可是在NT/2000下这个函数

的执行结果仅是注销而已，那么如何在NT/2000下实现关机呢？看看下面这个函数吧！

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);

}
