basic_ostream对象。这个析构函数不执行任何操作上的的基本streambuffer（rdbuf()）的析构函数派生的输出流，如std::basic_ofstreamstd::basic_ostringstream是负责调用析构函数的streambuffers.Original:
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 streambuffers.The text has been machine-translated via Google Translate.

#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.
