Localization functionality base class.
The facet class is the base class for a localization feature, such as money, time, and number printing. It provides common support for facets and reference management.
Facets may not be copied or assigned.
|std::locale::facet::facet||(||size_t||__refs = ||)|| throw ()
This is the constructor provided by the standard. If refs is 0, the facet is destroyed when the last referencing locale is destroyed. Otherwise the facet will never be destroyed.
|refs||The initial value for reference count.|
