std::locale::id::id(3)

NAME
std::locale::id::id - std::locale::id::id

Synopsis
   Defined in header <locale>
   id(); (1)
   id( const id& ) = delete; (2)
   1) Default constructor: creates an object of type std::locale::id with
   implementation-specific content.
   2) Copy constructor is deleted; std::locale::id is not copyable.

Notes
   Because locales and facets must be available for the IO stream objects with static
   storage duration, such as std::cout, typical implementations let implicit default
   constructor zero-initialize the contents of std::locale::id during static
   initialization (before constructors run for static objects), and when a facet is
   added to any locale for the first time, the locale completes initialization of the
   facet's id.
