NAME

std::moneypunct - std::moneypunct

Synopsis

Defined in header <locale>
template< class CharT, bool International = false >
class moneypunct;

The facet std::moneypunct encapsulates monetary value format preferences. Stream I/O
manipulators std::get_money and std::put_money use std::moneypunct through
std::money_get and std::money_put for parsing monetary value input and formatting
monetary value output.

Inheritance diagram

Four standalone (locale-independent) specializations are provided by the standard
library:

Defined in header <locale>
std::moneypunct<char> provides equivalents of the "C" locale preferences
std::moneypunct<wchar_t> provides wide character equivalents of the "C" locale
preferences
std::moneypunct<char, true> provides equivalents of the "C" locale preferences,
with international currency symbols
std::moneypunct<wchar_t, true> provides wide character equivalents of the "C" locale
preferences, with international currency symbols

In addition, every locale object constructed in a C++ program implements its own
(locale-specific) versions of these specializations.
