Hi Mathew,

I've been using basic_static_string<> class and I was trying to get a =
Starts With function like and I found this overload.
So I just wondering what's the n parameter for since it's not being used =
[I copied the implementation below]?=20

By the way would you consider adding an "attach constructor" to =
basic_static_string? (probably a change like that would be to much work =
with little gain)
I have a class that implements some of the basic_string functionality =
and allows me to do something like this:=20
    wchar_t wch[20];

    MyString<wchar_t> str(tch);

    str +=3D L"hi";
I have this necessity because I have to work with a lot of POD types.

Somewhere in Imperfect C++ you mentioned that you implemented a memory =
pool as part of a network server (just can't remember what =
page/chapter), I'm just wondering if is it a part of STLSoft libraries?
