FREEBSD::NVLIST_UP(3)

💖 FREEBSD::NVLIST_UP(3) 💖

okay so bestie, welcome to the FREEBSD::NVLIST_UP(3) page — a whole manual section for one tiny little std::unique_ptr glow-up, and honestly? she's serving convenience 💅

---

✨ NAME ✨

freebsd::nvlist_up — a std::unique_ptr specialization for name/value pairs. that's the whole vibe, no cap.

---

🎀 LIBRARY 🎀

library “libutil++” — that's where she lives 🫶

---

🦋 SYNOPSIS 🦋

#include <libutil++.hh>

using nvlist_up = std::unique_ptr<nvlist, nvlist_deleter>;

literally that's it. that's the whole incantation ✨

---

🌸 DESCRIPTION 🌸

so here's the tea, bestie: this class is a specialization of std::unique_ptr for nvlist_t objects. icon behaviour only 👑

and when an nvlist_t object managed by an instance of this class is disposed, nvlist_destroy(3) gets invoked to dispose of the object. automatic cleanup, no manual teardown, no leaking, we simply do not do that here 💀

it's giving main character energy with a deleter. iykyk.

---

🔥 EXAMPLES 🔥

freebsd::nvlist_up nvl(nvlist_create(0));
nvlist_add_number(nvl.get(), "answer", 42);
nvlist_add_bool(nvl.get(), "valid", true);
// `nvl' is implicitly destroyed

look at her go 🥹 create it, add a number, add a bool, then just let go and the destructor handles the rest. the comment says it all: // nvl' is implicitly destroyed— no manualnvlist_destroy` call in sight. obsessed.

• nvlist_destroy(3) — the one doing the actual cleanup work behind the scenes, so show her some respect fr fr 💖

🌈 reminder bestie: the magic here is the deleter. you don't call destroy yourself — the unique_ptr does it for you, on purpose, by design. that's not a bug, that's the entire point ⭐
