Cicularbuffer in function

[bergeronnext]

Hi i can use the name buffer in fonction parameter

like. Int MyFonction (???? Buffer){

For(i=0,i<buffer.size(),i++){

Int avt +=Buffer[i]

}
Return avt
}
My code is only a exemple
I dont know how to set the type of buffer

First of all, your question is not clear at all, so my answer is my best guess of what you might have been asking.

My guess then is you want to pass an instance of CircularBuffer to a function, which you can obviously do:

long sum(CircularBuffer<int, 100> &cb) {
  long result = 0;
  for (int i = 0; i < cb.size(); i++)
    result += cb[i];
  return result;
}

You can call such function as sum(buffer) where buffer must be an instance of CircularBuffer<int, 100>.

You can define a templated function if you put the following in a header file though:

template<size_t S>
long sum(CircularBuffer<int, S> &cb) {
  long result = 0;
  for (int i = 0; i < cb.size(); i++)
    result += cb[i];
  return result;
}

As you can see the size is now variable, so the sum function can work on any buffer of any size, given they are all storing int values.

Anyways, this is plain C++ programming, so please refer to a good C++ manual or tutorial covering templates.

Thanks for your quick reply, that’s exactly what y wanted. Sorry for my question which was imprecise.
