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.

explicit moneypunct_byname( const char* name, std::size_t refs = 0 ); | ||
explicit moneypunct_byname( const std::string& name, std::size_t refs = 0 ); | (since C++11) |
Constructs a new std::moneypunct_byname
facet for a locale with name
.
refs
is used for resource management: if refs == 0
, the implementation destroys the facet, when the last std::locale
object holding it is destroyed. Otherwise, the object is not destroyed.
name | - | the name of the locale |
refs | - | the number of references that link to the facet |
protected: ~moneypunct_byname(); |
Destroys the facet.

none | whitespace is permitted but not required except in the last position, where whitespace is not permitted |
space | one or more whitespace characters are required |
symbol | the sequence of characters returned by moneypunct::curr_symbol is required |
sign | the first of the characters returned by moneypunct::positive_sign or moneypunct::negative_sign is required |
value | the absolute numeric monetary value is required |
This example demonistrates how to apply monetary formatting rules of another language without changing the rest of the locale.
#include <iostream> #include <iomanip> #include <locale> int main() { long double mon = 1234567; std::locale::global(std::locale("en_US.utf8")); std::wcout.imbue(std::locale()); std::wcout << L"american locale : " << std::showbase << std::put_money(mon) << '\n'; std::wcout.imbue(std::locale(std::wcout.getloc(), new std::moneypunct_byname<wchar_t>("ru_RU.utf8"))); std::wcout << L"american locale with russian moneypunct: " << std::put_money(mon) << '\n'; }
Output:
american locale : $12,345.67 american locale with russian moneypunct: 12 345.67 руб
