std::numpunct::~numpunct(3)

NAME
std::numpunct::~numpunct - std::numpunct::~numpunct

Synopsis
   Defined in header <locale>
   protected: ~numpunct();
   Destructs a std::numpunct facet. This destructor is protected and virtual (due to
   base class destructor being virtual). An object of type std::numpunct, like most
   facets, can only be destroyed when the last std::locale object that implements this
   facet goes out of scope or if a user-defined class is derived from std::numpunct and
   implements a public destructor.

Example
// Run this code
 #include <iostream>
 #include <locale>
 struct Destructible_numpunct : public std::numpunct<wchar_t>
 {
     Destructible_numpunct(std::size_t refs = 0) : numpunct(refs) {}
     // note: the implicit destructor is public
 };
 int main()
 {
     Destructible_numpunct dc;
     // std::numpunct<wchar_t> c; // compile error: protected destructor
 }
