如何使用程序重启计算机?

如题：

typedef int (CALLBACK *SHUTDOWNDLG)(int); //显示关机对话框函数的指针
HINSTANCE hInst = LoadLibrary("shell32.dll"); //装入shell32.dll
SHUTDOWNDLG ShutDownDialog; //指向shell32.dll库中显示关机对话框函数的指针
if(hInst != NULL)
{
//获得函数的地址并调用之
ShutDownDialog = (SHUTDOWNDLG)GetProcAddress(hInst,(LPSTR)60);
(*ShutDownDialog)(0);
}

if(dwVersion < 0x80000000)

}


LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid); //获得本地机唯一的标识
tkp.PrivilegeCount = 1;

AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0); //调整获得的权限

if (GetLastError() != ERROR_SUCCESS)
{
MessageBox("AdjustTokenPrivileges enable failed!");
}

BOOL fResult =InitiateSystemShutdown(
"Lf",
"WINDOWS将在上面的时间内关机，请做好保存工作!", // 显示的消息
10, // 关机所需的时间
TRUE,
TRUE); //设为TRUE为重起，设为FALSE为关机

if(!fResult)
{
MessageBox("InitiateSystemShutdown failed.");
}
}

else
{//95
ExitWindowsEx(EWX_FORCE | EWX_SHUTDOWN,0);
}

以下代码能实现注销，关闭，重起，挂起计算机以及关闭显示器，运行屏保的功能
98下使用不需要调用EnablePrivilege
//shutdown and reboot system
//uFlag=
#define SD_LOGOFF EWX_LOGOFF
#define SD_SHUTDOWN EWX_POWEROFF
#define SD_REBOOT EWX_REBOOT
#define SD_SUSPEND 0x00000020
//if bForce==false, the display is in low power.
// bForce==true , turn off the display .
#define SD_MONITOR 0x00000040
//run the current screen saver application
#define SD_SCREENSAVE 0x00000080 //the parameter bForce will be ignored

//change the privilege of this process.
BOOL EnablePrivilege(LPCTSTR lpszPrivilegeName,BOOL bEnable)
