Detailed Description

template<typename _CharT>

class std::messages< _CharT >" Primary class template messages.

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

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

Definition at line 44 of file messages_members.h.

template<typename _CharT > std::messages< _CharT >::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.
__refs Refcount to pass to the base class.
