libnvme_ns_get_uuid(9)

✨ libnvme_ns_get_uuid 💅

okay so bestie, welcome to the libnvme_ns_get_uuid</p> page — it's part of the libnvme API manual, section 9, and it's literally the whole vibe of "hey, what's the UUID on this namespace?" 🦋

---

🌸 NAME 🌸

libnvme_ns_get_uuid — get uuid. that's it. that's the whole thing. Get uuid. 🎀

---

⭐ SYNOPSIS ⭐

int libnvme_ns_get_uuid (const struct libnvme_ns *p , const unsigned
char **uuid , const unsigned char *dflt );

like, no cap, that's the signature exactly as it is — don't go "fixing" the spacing, iykyk 👑

---

💖 ARGUMENTS 💖

• p — the struct libnvme_ns instance you're querying. your main character ✨ the namespace in question.
• uuid — where the value gets stored on success. like, the cute little drop-off spot 🫶
• dflt — the value to store in uuid on failure. the backup plan, the safety net, the "if it all goes sideways at least you have this" 😭

---

🔥 RETURN 🔥

• 0 on success — slay, it worked 💅
• -ENOENT if the attribute does not exist — the attribute simply isn't there, no drama, it's giving "not found" 🌸
• or a negative errno on failure — other stuff went wrong, check your errno bestie 💀

ngl, everything here is either a clean 0, a -ENOENT because the attribute doesn't exist, or some negative errno from a failure. no invented behaviour, no extra lore — that's the whole return story fr fr 🧚

and that's the page!! mwah 💜 this was the libnvme_ns_get_uuid man page from the libnvme API manual, dated October 2026 — go forth and get those uuids, bestie, you're gonna ate 👑🎀
