What WCHAR * to wstring does internally?

I have a WCHAR array (say WCHAR *wszName). I want to convert it to wstring. So, I do the following:-

wstring wstrName(wszName);

It works. But I want to know what internally happens when the conversion takes place. For example, does it allocate some new buffer? While debugging an application, I looked into the code of the conversion, but could not understand it. Could you please post the code of conversion and explain it to me?

Thanks.

Yes I think in most inplementations it would allocate a buffer.

There would be no point me posting the code I might have because the code is platform dependent and my not be working in the same way the code on your platform is working. Why don't you post the code from your platform and we will try to explain it.
