💖 libnvme(2) — the API Manual, bestie edition 💖

okay so welcome to the libnvme manual page, section 2, and today's main character is a lil struct called nvme_media_unit_stat_desc — yes that's a mouthful, yes it ate, we move 💅

---

✨ NAME ✨

struct nvme_media_unit_stat_desc — the Media Unit Status Descriptor 🎀

---

🌸 SYNOPSIS 🌸

like, here's the whole vibe, laid out exactly as it lives in the code:

struct nvme_media_unit_stat_desc {
    __le16 muid;
    __le16 domainid;
    __le16 endgid;
    __le16 nvmsetid;
    __le16 cap_adj_fctr;
    __u8 avl_spare;
    __u8 percent_used;
    __u8 mucs;
    __u8 cio;
 };

---

🦋 Members 🦋

okay bestie, field-by-field, no skips, we're doing all of them 🌈

• muid — the Media Unit Identifier. that's the name tag every media unit wears at the party.
• domainid — the Domain Identifier. which domain this cutie belongs to.
• endgid — the Endurance Group Identifier. yes, endurance, she's got stamina 💪
• nvmsetid — the NVM Set Identifier. which NVM set she runs with.
• cap_adj_fctr — the Capacity Adjustment Factor. lowkey the math girlie of the struct.
• avl_spare — Available Spare. how much spare is still in the tank ✨
• percent_used — Percentage Used. how much wear she's already been through, ngl 😭
• mucs — the Number of Channels attached to media units. yes, channels, plural, we counted.
• cio — the Channel Identifiers Offset. where the channel identifiers start, fr fr.

---

and that's the whole struct, every single field, nothing left behind, periodt. 🫶

ngl there are no options, no exit statuses, no environment variables and no errors on this page — it's literally just the descriptor and her nine fields. iconic of her honestly.
