virtual ~basic_ostream(); | ||
Destroys thebasic_ostream object. This destructor does not perform any operation on the underlying streambuffer (rdbuf()): the destructors of the derived output streams such asstd::basic_ofstream andstd::basic_ostringstream are responsible for calling the destructors of the stream buffers.
#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.
