std::basic_...am::is_open(3)

🌸 NAME 🌸

Okay bestie, welcome to the std::basic_...am::is_open(3) page from the C++ Standard Libary manual. The NAME situation is std::basic_ofstream::is_open — std::basic_ofstream::is_open. Yes, it's the same on both sides of the dash, and that's on purpose. 💅

✨ Synopsis ✨

Here's the whole signature, no cap:

bool is_open() const;

This checks if the file stream has an associated file. 💖

It effectively calls rdbuf()->is_open(). That's the whole vibe.

🧸 Parameters 🧸

(none) — literally no parameters, bestie. Nothing to pass in. 🫶

🎀 Return value 🎀

true if the file stream has an associated file; false otherwise. Simple, iconic, done. ✨

😭 Example 😭

This section is incomplete. Reason: no example. Not me opening the example section and finding it empty. 💀

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
