The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at <cvt-wbuffer>.

The header <cvt/wstring> in previous versions of Visual Studio defined the template class wbuffer_convert Class in the stdext::cvt namespace. The header is maintained for backward compatibility. New code should use the version of the class that is defined in <locale> in the std namespace

#include <cvt/wbuffer>
