libnvme_ns_get_csi(9)

✨ libnvme_ns_get_csi(9) ✨

okay so bestie, welcome to the libnvme API manual 💖 this one is about a tiny lil function called libnvme_ns_get_csi, and honestly? she's a vibe check for your namespace. let's get into it 🦋

---

🌸 NAME 🌸

libnvme_ns_get_csi — bestie, it gets the csi. that's it. that's the whole job 💅

---

⭐ SYNOPSIS ⭐

int libnvme_ns_get_csi (const struct libnvme_ns *p , enum nvme_csi *csi
, enum nvme_csi dflt );

like, look at her go. three args, one int back. iconic behavior fr fr 👑

---

🎀 ARGUMENTS 🎀

• p — the struct libnvme_ns instance you wanna query. this is your main character, the namespace in question 🫶
• csi — where the value gets stored on success. think of it as the lil basket you're handing over so the function has somewhere to drop the goods 🧺
• dflt — the value to store in csi on failure. so if things go sideways, at least csi isn't just sitting there empty and confused 😭 it's giving safety net energy

---

💜 RETURN 💜

• 0 on success — slay, we love a clean zero ✨
• -ENOENT if the attribute does not exist — like, she looked and there's literally nothing there 💀
• or a negative errno on failure — any other bad vibes land here 🙈

ngl, always check the return value. 0 is the happy path, everything else is your cue to go read the errno. no cap 🔥

---

and that's the whole page, bestie! short, sweet, and absolutely ate 🌈
