NAME

std::basic_ostream<CharT,Traits>::~basic_ostream - std::basic_ostream<CharT,Traits>::~basic_ostream

Synopsis


virtual ~basic_ostream();


Destroys the basic_ostream object. This destructor does not perform any operation on the underlying streambuffer (rdbuf()): the destructors of the derived output streams such as std::basic_ofstream and std::basic_ostringstream are responsible for calling the destructors of the stream buffers.

Example


// Run this code


  #include <sstream>
  #include <iostream>
  void add_words(std::streambuf* p)
  {
      std::ostream buf(p); // buf shares the buffer with s
      buf << " is the answer";
  } // calls the destructor of buf. p remains unaffected
  int main()
  {
      std::ostringstream s;
      s << 42;
      add_words(s.rdbuf());
      s << ".";
      std::cout << s.str() << '\n';
  }

Output:


  42 is the answer.
