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
Run this code
#include <iostream> #include <sstream> 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.
