std::moneypunct_byname is a std::moneypunct facet which encapsulates monetary formatting preferences of a locale specified at its construction.

[edit] Specializations
The standard library is guaranteed to provide every specialization that satisfies the following type requirements:
-
CharTis one of char and wchar_t, and -
Intlis a possible specialization on a bool parameter.

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.
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();
~moneypunct_byname();
Destroys the facet.

Description
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 std::moneypunct::curr_symbol is required
sign
the first of the characters returned by std::moneypunct::positive_sign or std::moneypunct::negative_sign is required
value
the absolute numeric monetary value is required
[edit] Example
This example demonstrates how to apply monetary formatting rules of another language without changing the rest of the locale.
Run this code
#include <iomanip> #include <iostream> #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ドル.67 american locale with russian moneypunct: 12 345.67 руб
