Qt equivalent of timeGetTime()

Question

Is there in the QT libraries an equivalent of the timeGetTime() function of the Windows.h header? I wish my code was as platform-independent as possible. I know the <chrono> header exists, but I would like something that returns the value in DWORD

float AudioThread::br()
{
    QTime tmp(0,0);
    DWORD time = tmp.msecsSinceStartOfDay();
    QWORD pos = BASS_StreamGetFilePosition(chan, BASS_FILEPOS_CURRENT);
        if (pos != lastpos) {
          lasttime = time;
          lastpos = pos;
        }
    }
    qDebug() << tmp.msecsSinceStartOfDay() << pos;
    return 8.0 * (pos - lastpos) / (time - lasttime);
}

Inserting this code into a QTimer, tmp.msecsSinceStartOfDay() always returns 0

Can you help me?

Thanks in advance

It is a bit hard to guess, what you really want. Looking at your code, you set tmp to 0, afterwards you calculate the difference of tmp(which is still at 0) with 0 (the start of the day) which makes your variable time = 0-0 = 0. Perfectly correct but not what you want. If you want to know, what the current time is, you could use

QTime tm = QTime::currentTime();
DWORD dtime = tm.msecsSinceStartOfDay();

BTW: I would not use a variable named time as this might create confusion with the time() library function. I have seen very strange behaviour after using a variable named 'time'.
