std::basic_...sic_filebuf(3)

💖 NAME 💖

std::basic_filebuf::~basic_filebuf — bestie, this is literally the destructor for std::basic_filebuf, and yes the page header is doing that cursed std::basic_...sic_filebuf(3) abbreviation thing again (iykyk, it's the C++ Standard Libary man page, we don't talk about the typo 💀).

---

✨ Synopsis ✨

virtual ~basic_filebuf();

Okay so real talk: it calls close() to close the associated file, and then destructs all the other members of basic_filebuf. That's the whole vibe check.

And the important part 👑: if an exception happens during the destruction of the object — including inside that call to close() — it gets caught and not rethrown. No drama, no surprise throws escaping a destructor, we simply do not allow that energy here 💅.

🎀 Parameters 🎀

(none) — not a single one, she takes no arguments, main character energy fr fr 🦋

🌸 Return value 🌸

(none) — destructors don't return things, that's just how it is, periodt ✨

🧚 Notes 🧚

Typically called by the destructor of std::basic_fstream. So like, you're probably never calling this yourself — your fstream is out here doing it for you behind the scenes 🫶.

Reason: no example 🙈

(yes bestie, the page literally says that, I'm not gatekeeping an example from you, there just isn't one 😭)

💜 Defect reports 💜

The following behavior-changing defect reports were applied retroactively to previously published C++ standards. Retroactive glow-ups, we love to see it 🌈

• LWG 622 — applied to C++98 — the behavior as published was that it was unclear how to handle the exception thrown during destruction; the correct behavior is that it is caught but not rethrown 💖
