Question

I am writing a program in c++ where I need to call a function at periodic time intervals, say every 10ms or so. I\'ve never done anything related to time or clocks in c++, i

If you're coding with Visual C++, you could add a timer element to the form you want to call a periodic function (here it's called my form is MainForm, and my timer MainTimer). Add a call to the tick event in the "Events". The designer will add such line in your .h file:

this->MainTimer->Enabled = true;
this->MainTimer->Interval = 10;
this->MainTimer->Tick += gcnew System::EventHandler(this, &MainForm::MainTimer_Tick);

Then, at each interval (specified in ms), the application will call this function

private: System::Void MainTimer_Tick(System::Object^  sender, System::EventArgs^  e) {
   /// Enter your periodic code there
}
