QT程序实现windows重启、关机功能

1、记得要加入头文件：#include

2、代码

bool MainForm::shutDownSystem()
{
    HANDLE hToken;
    TOKEN_PRIVILEGES tkp;

    //获取进程标志
        if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
            return false;

        //获取关机特权的LUID
        LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,    &tkp.Privileges[0].Luid);
        tkp.PrivilegeCount = 1;
        tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

        //获取这个进程的关机特权
        AdjustTokenPrivileges(hToken, false, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
        if (GetLastError() != ERROR_SUCCESS) return false;

        // 强制关闭计算机
        //if (  !ExitWindow***(EWX_SHUTDOWN | EWX_FORCE,
            // SHTDN_REASON_MAJOR_OPERATINGSYSTEM | SHTDN_REASON_MINOR_UPGRADE |  SHTDN_REASON_FLAG_PLANNED))
        if (  !ExitWindow***(EWX_REBOOT | EWX_FORCE, 0))
             return false;
        return true;

}
