Thanks Steven,

But this is desired?
In this way is difficult to work on indexes eg with operator[].
What I expect is that the value at index 0 is always at position
Buffer[0] unless it will be replaced by another value...

Suppose I have a producer that write to the buffer and some consumer
that reads from it, each of them at different locations, this could be
accomplish only with iterators?

Daniele.
