<streambuf> <iostream>
std::wstreambuf
typedef basic_streambuf<wchar_t> wstreambuf;
Base buffer class for streams (wide)
This template is designed as base virtual class for all stream buffer classes that handle wide characters (of type wchar_t). See basic_streambuf for more info on the template.
It instantiates basic_streambuf with the following template parameters:
| template parameter | definition | comments |
|---|
| charT | wchar_t | Aliased as member char_type |
| traits | char_traits<wchar_t> | Aliased as member traits_type |
