std::istrst...~istrstream(3)

🌸 NAME 🌸

okay bestie, welcome to the std::istrst...~istrstream(3) page from the C++ Standard Libary 💅 this one is all about the destructor, and it's lowkey iconic.

std::istrstream::~istrstream - std::istrstream::~istrstream

✨ Synopsis ✨

virtual ~istrstream();

so yeah, it's virtual ✨ and here's the timeline tea: deprecated in C++98, removed in C++26 😭. It destroys a std::istrstream object, which also destroys the member std::strstreambuf. periodt.

🎀 Parameters 🎀

(none) — literally no parameters, bestie. zero. nada. 🫶

🦋 Notes 🦋

okay so the notes are giving “don't panic about leaks” energy: 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. slay for safety, no cap ✨

💖 Example 💖

// Run this code

#include <iostream>
#include <strstream>

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

🌈 Output 🌈

1.234

and that's the tea 🍓 this page came from http://cppreference.com, dated/versioned 2024.06.10, and it's the std::istrst...~istrstream(3) manual page. mwah 💋
