FREEBSD::FILE_UP(3)

🌸 NAME 🌸

okay so this is the FREEBSD::FILE_UP(3) page, bestie — and it's literally about freebsd::FILE_up, the std::unique_ptr specialization for stdio FILE objects. No cap, that's the whole name vibe. 💅

---

📚 LIBRARY 📚

library “libutil++” — yep, that's the one, bestie. 🫶

---

✨ SYNOPSIS ✨

#include <libutil++.hh>

using FILE_up = std::unique_ptr<FILE, fclose_deleter>;

---

💖 DESCRIPTION 💖

This class is a specialization of std::unique_ptr for stdio FILE objects. Iconic behavior, honestly. ✨

When a FILE object managed by an instance of this class is disposed, fclose(3) is invoked to dispose of the FILE object. That's it. That's the slay. 🎀

🧪 EXAMPLES 🧪

             freebsd::FILE_up fp(fopen("foo.txt", "w"));
             if (!fp)
                     err(1, "fopen");
             fprintf(fp.get(), "hello0);
             // `fp' is implicitly closed on destruction
