std::moneypunct_byname is a std::moneypunct facet which encapsulates monetary formatting preferences of a locale specified at its construction.
The standard library is guaranteed to provide every specialization that satisfies the following type requirements:
CharT is one of char and wchar_t, and Intl is a possible specialization on a bool parameter. | Member type | Definition |
|---|---|
pattern | std::money_base::pattern |
string_type | std::basic_string<CharT> |
| (constructor) | constructs a new moneypunct_byname facet (public member function) |
| (destructor) | destroys a moneypunct_byname facet (protected member function) |
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.

| Enumeration constant | Definition |
|---|---|
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 |
This example demonstrates how to apply monetary formatting rules of another language without changing the rest of the locale.
#include <iomanip>

std::wcout << L"american locale with russian moneypunct: "

}Output:
