std::basic_ostream<CharT,Traits>::~basic_ostream
From cppreference.com
< cpp | io | basic ostream
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
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.
