std::basic_ostream<CharT,Traits>::basic_ostream - cppreference.com ([original](http://en.cppreference.com/w/cpp/io/basic%5Fostream/basic%5Fostream.html)) (raw)

| 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.

[edit] Example

#include #include   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:
