C++ Library - <wstreambuf>

Introduction

It is a ase buffer class for streams (wide).

Below is definition of std::wstreambuf.

typedef basic_streambuf<wchar_t> wstreambuf;

charT − Character type.
traits − Character traits class that defines essential properties of the characters used by stream objects.
