std::moneypunct_byname(3) C++ Standard Libary std::moneypunct_byname(3) NAME std::moneypunct_byname - std::moneypunct_byname Synopsis Defined in header <locale> template< class CharT, bool Intl = false > class moneypunct_byname : public std::moneypunct<CharT, Intl>; std::moneypunct_byname is a std::moneypunct facet which encapsulates monetary formatting preferences of a locale specified at its construction. Two specializations are provided by the standard library Defined in header <locale> std::moneypunct_byname<char, Intl> locale-specific std::money- punct facet for narrow character I/O std::moneypunct_byname<wchar_t, Intl> locale-specific std::money- punct facet for wide character I/O Member types Member type Definition pattern std::money_base::pattern string_type std::basic_string<CharT> Member functions constructor constructs a new moneypunct_byname facet (public member function) destructor destroys a moneypunct_byname facet (protected member function) std::moneypunct_byname::moneypunct_byname explicit moneypunct_byname( const char* name, std::size_t refs = 0 ); explicit moneypunct_byname( const std::string& name, std::size_t refs (since C++11) = 0 ); Constructs a new std::moneypunct_byname facet for a locale with name. refs is used for resource management: if refs == 0, the implementa- tion destroys the facet, when the last std::locale object holding it is destroyed. Otherwise, the object is not destroyed. Parameters name - the name of the locale refs - the number of references that link to the facet std::moneypunct_byname::~moneypunct_byname protected: ~moneypunct_byname(); Destroys the facet.
