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.
