I essentially want to reconstruct the getTickCount() windows function so I can use it in basic C++ without any non standard libraries or even the STL. (So it complies with the libraries supplied with the Android NDK)

I have looked at

But I'm still unsure whether it is possible to replicate the getTickCount windows function with the time library.

Can anyone point me in the right direction as to how to do this or even if its possible?

An overview of what I want to do:

I want to be able to calculate how long an application has been "doing" a certain function. 

So for example I want to be able to calculate how long the application has been trying to register with a server 

I am trying to port it from windows to run on the linux based Android, here is the windows code:

---

```
int TimeoutTimer::GetSpentTime() const
{
if (m_On)
{
    if (m_Freq>1)
    {
        unsigned int now;
        QueryPerformanceCounter((int*)&now);
        return (int)((1000*(now-m_Start))/m_Freq);
    }
    else
    {
        return (GetTickCount()-(int)m_Start);
    }
}
return -1;
}

```
