ctype_byname class template — Facet for classifying characters

Synopsis

template <typename charT>
class ctype_byname : public ctype<charT>
{
public:
  typedef ctype<charT>::mask mask;
  explicit ctype_byname(const char*, size_t refs = 0);
protected:
  //  . . .  Same virtual functions as in ctype
};

The ctype_byname class template is a facet for classifying characters; it uses a named locale. The ctype_byname<char> and ctype_byname<wchar_t> instantiations are standard.
