libnvme(9)

✨ NAME ✨

okay so this is the libnvme(9) manual page bestie, and it's all about enum nvme_ns_id_desc_nidt_lens — literally just the Namespace Identifier Descriptor Type Lengths 💅 like, the lengths of the namespace ID descriptor types, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

here's the enum, no cap, copy it exactly:

enum nvme_ns_id_desc_nidt_lens {
    NVME_NIDT_EUI64_LEN ,
    NVME_NIDT_NGUID_LEN ,
    NVME_NIDT_UUID_LEN ,
    NVME_NIDT_CSI_LEN

};

that's it. four little constants, living their best life 🦋

💖 Constants 💖

okay so these are the members, and each one is a length in bytes — let's get into it 🫶

• NVME_NIDT_EUI64_LEN — IEEE Extended Unique Identifier length, which is 8 bytes 🍓
• NVME_NIDT_NGUID_LEN — Namespace Globally Unique Identifier length, and that one's 16 bytes ✨
• NVME_NIDT_UUID_LEN — Universally Unique Identifier length, also 16 bytes 🌈
• NVME_NIDT_CSI_LEN — Command Set Identifier length, and this cutie is just 1 byte 🙈

fr fr that's the whole page — four constants, all lengths, no drama 💀

and that's a wrap bestie!! this was enum nvme_ns_id_desc_nidt_lens from the libnvme(9) API Manual, October 2026 edition 👑💜 go forth and know your descriptor lengths, iykyk 🧚
