Defined in header <locale> | ||
|---|---|---|
template< class CharT > class messages; |
Class template std::messages is a standard locale facet that encapsulates retrieval of strings from message catalogs, such as the ones provided by GNU gettext or by POSIX catgets.
The source of the messages is implementation-defined.
Inheritance diagram.
Two standalone (locale-independent) specializations are provided by the standard library:
Defined in header <locale> |
|
|---|---|
std::messages<char> | accesses narrow string message catalog |
std::messages<wchar_t> | accesses wide string message catalog |
In addition, every locale object constructed in a C++ program implements its own (locale-specific) versions of these specializations.
