NAME¶

std::ctype::~ctype - std::ctype::~ctype

Synopsis¶

Defined in header <locale>
protected: ~ctype();

Destructs a std::ctype facet. This destructor is protected and virtual (due to base
class destructor being virtual). An object of type std::ctype, 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::ctype and implements a
public destructor.

Example¶

// Run this code

#include <iostream>
#include <locale>

struct Destructible_ctype : public std::ctype<wchar_t>
{
Destructible_ctype(std::size_t refs = 0) : ctype(refs) {}
// note: the implicit destructor is public
};

int main()
{
Destructible_ctype dc;
// std::ctype<wchar_t> c; // compile error: protected destructor
}
