Detailed Description

template<typename _CharT>
class std::messages< _CharT >

This facet encapsulates the code to retrieve messages from message catalogs. The only thing defined by the standard for this facet is the interface. All underlying functionality is implementation-defined.

This library currently implements 3 versions of the message facet. The first version (gnu) is a wrapper around gettext, provided by libintl. The second version (ieee) is a wrapper around catgets. The final version (default) does no actual translation. These implementations are only provided for char and wchar_t instantiations.

The messages template uses protected virtual functions to provide the actual results. The public accessors forward the call to the virtual functions. These virtual functions are hooks for developers to implement the behavior they require from the messages facet.

Constructor & Destructor Documentation

messages

(

size_t

__refs = 0

)

[explicit]

Constructor performs initialization.

This is the constructor provided by the standard.

Parameters:

refs

Passed to the base facet class.

messages	(	__c_locale	__cloc,
		const char *	__s,
		size_t	__refs = 0
	)			[explicit]

Internal constructor. Not for general use.

This is a constructor for use by the library itself to set up new locales.

Parameters:

	cloc	The "C" locale.
	s	The name of a locale.
