std::basic_istream<CharT,Traits>::~basic_istream
virtual ~basic_istream(); |
Destructs the input stream.
Notes
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.
Example
#include <sstream>
#include <iostream>
void print_stringbuf(std::streambuf* p)
{
std::istream buf(p); // buf shares the buffer with s1
int 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
