💖 libnvme(2) — API Manual 💖

okay bestie, welcome to the <enum> part of the libnvme API manual 💅 if you're here it's because you're poking at namespace identifier descriptor types, and honestly? iconic behavior. let's get into it.

---

✨ NAME ✨

enum nvme_ns_id_desc_nidt — the known namespace identifier types 👑

🌸 SYNOPSIS 🌸

enum nvme_ns_id_desc_nidt {
    NVME_NIDT_EUI64 ,
    NVME_NIDT_NGUID ,
    NVME_NIDT_UUID ,
    NVME_NIDT_CSI

};

so yeah, that's the whole enum, that's the vibe check right there 🦋

🎀 Constants 🎀

each one of these lil guys is a possible value for the identifier type, and here's exactly what each means:

• NVME_NIDT_EUI64 — IEEE Extended Unique Identifier, and the NID field holds a copy of the EUI64 field in the struct nvme_id_ns.eui64. she's literally just the EUI64 with a pass-through, no cap 💫
• NVME_NIDT_NGUID — Namespace Globally Unique Identifier, and the NID field holds a copy of the NGUID field in struct nvme_id_ns.nguid. same energy, different field 🫶
• NVME_NIDT_UUID — the NID field holds a 128-bit Universally Unique Identifier (UUID) as specified in RFC 4122. very main character of her honestly 🌈
• NVME_NIDT_CSI — the NID field holds the command set identifier. the way that she just tells you the command set... obsessed 🔥

🦋 SEE ALSO 🦋

hmm, there's genuinely nothing else listed in this one bestie, so the see-also moment is just us, vibing 🧚💜

fr fr, that's the whole page. nothing left unread, every constant accounted for. slay. ✨

and that's a wrap, bestie! this was enum nvme_ns_id_desc_nidt from the libnvme(2) API Manual, dated July 2026. go forth and identify your namespaces with confidence 💅💖🎀
