std::wbuffer_convert::~wbuffer_convert(3)

NAME
std::wbuffer_convert::~wbuffer_convert - std::wbuffer_convert::~wbuffer_convert

Synopsis
   Defined in header <locale>
   ~wbuffer_convert();
   Destroys the wbuffer_convert object and deletes the pointer to the conversion facet.

Notes
   Some implementations are able to delete any facet, including the locale-specific
   facets with protected destructors. Other implementations require the facet to have a
   public destructor, similar to the locale-independent facets from <codecvt>.

Example
// Run this code
 #include <locale>
 #include <utility>
 #include <iostream>
 #include <codecvt>
 // utility wrapper to adapt locale-bound facets for wstring/wbuffer convert
 template<class Facet>
 struct deletable_facet : Facet
 {
     template<class ...Args>
     deletable_facet(Args&& ...args) : Facet(std::forward<Args>(args)...) {}
     ~deletable_facet() {}
 };
 int main()
 {
     // GB18030 / UCS4 conversion, using locale-based facet directly
     // typedef std::codecvt_byname<char32_t, char, std::mbstate_t> gbfacet_t;
     // Compiler error: "calling a protected destructor of codecvt_byname<> in ~wbuffer_convert"
     // std::wbuffer_convert<gbfacet_t, char32_t> gbto32(std::cout.rdbuf(),
     // new gbfacet_t("zh_CN.gb18030"));
     // GB18030 / UCS4 conversion facet using a facet with public destructor
     typedef deletable_facet<std::codecvt_byname<char32_t, char, std::mbstate_t>> gbfacet_t;
     std::wbuffer_convert<gbfacet_t, char32_t> gbto32(std::cout.rdbuf(),
                        new gbfacet_t("zh_CN.gb18030"));
 } // destructor called here
