std::istrstream::istrstream (3) Linux Manual Page

std::istrstream::~istrstream – std::istrstream::~istrstream

Synopsis

virtual ~istrstream();

Destroys a std::istrstream object, which also destroys the member std::strstreambuf.

Parameters

(none)

Notes

The constructors of std::istrstream do not create the underlying std::strstreambuf in dynamically allocated mode, so the memory leaks that are possible with std::ostrstream::~ostrstream or std::strstream::~strstream do not apply.

Example

// Run this code

#include <strstream>

#include <iostream>
int main()

{
    {
        std::istrstream s("1.234");
        double d;
        s >> d;
        std::cout << d << '\n';
    } // destructor called
}

Output:

  1.234
