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::moneypunct facet for narrow character I/O |
| std::moneypunct_byname<wchar_t, Intl> | locale-specific std::moneypunct facet for wide character I/O |

| (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 = 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(); |
||
Destroys the facet.

|
one or more whitespace characters are required |
symbol
|
the sequence of characters returned by std::moneypunct::curr_symbol is required |

the first of the characters returned by std::moneypunct::positive_sign or std::moneypunct::negative_sign is required |
value
|

Example
This example demonstrates how to apply monetary formatting rules of another language without changing the rest of the locale.
Run this code
#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
