[modifica]Note

Questo distruttore non si esegue alcuna operazione sul streambuffer sottostante (rdbuf()): i distruttori dei flussi di input derivati ​​come std::basic_ifstream e std::basic_istringstream sono responsabili per chiamare i distruttori delle streambuffers.
Original:
This destructor does not perform any operation on the underlying streambuffer (rdbuf()): the destructors of the derived input streams such as std::basic_ifstream and std::basic_istringstream are responsible for calling the destructors of the streambuffers.

[modifica]Esempio

#include <sstream>#include <iostream>   void print_stringbuf(std::streambuf* p){std::istream buf(p);// buf shares the buffer with s1int n; buf >> n;std::cout<< n;}// calls the destructor of buf. p remains unaffected   int main(){std::istringstream s1("10 20"); print_stringbuf(s1.rdbuf());int n; s1 >> n;std::cout<<','<< n <<'\n';}

Output:

10,20
