Appending an int to a wchar_t*? ..unresolved, lack of concrete example

I am building a string of int values, stored in a wchar_t*. If I have an integer, how can I append it onto the end of a wchar_t*? Windows only solutions are fine for this and I'd rather not include boost :)

Use a wide version of stringstream and the '<<' operator. The correct operator to perform the conversion for you should be defined.

If I am missing some subtlety here you could depend on boost and use this.

I'm still a fan of secure versions of sprintf and so is Herb Sutter :D.

How about boost lexical_cast<>

std::wstring  data;

data += boost::lexical_cast<std::wstring>(53);
data.c_str() // This is wchar_t*

If you are using windows you can always use wsprintf ie 

wsprintf( newStr, L"%s%d", oldStr, yourInt );

I'm sure there will be some equivalent for non-windows ...
