virtual ~istrstream();

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

[edit] Parameters

(none)

[edit] 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.

[edit] Example

#include <strstream>
#include <iostream>
 
int main()
{
    {
        std::istrstream s("1.234");
        double d;
        s >> d;
        std::cout << d << '\n';
    } // destructor called
}

Output:

1.234
