libnvme(2)

💖 libnvme(2) — the manual, but make it cute 💖

okay bestie, listen. you're reading the API Manual for libnvme, section 2, and today's main character is a struct. yes, a struct. and honestly? she's giving ✨infrastructure✨. let's get into it.

---

🌸 NAME 🌸

struct nvme_reachability_association_desc — the Reachability Association Descriptor 💅

like, that's her full government name. no nicknames. use it with respect.

---

🎀 SYNOPSIS 🎀

here's the whole fit, laid out exactly as she wears it:

struct nvme_reachability_association_desc {
    __le32 rasid;
    __le32 nrid;
    __le64 chngc;
    __u8 rac;
    __u8 rsvd17[15];
    __le32 rgid[];
};

no cap, that's the entire thing. she's small. she's structured. she knows what she's about. 🦋

👑 Members 👑

okay so let's meet the cast, one field at a time, because every single one of them matters:

• rasid — the Reachability Association ID. her little ID badge. who she is in this association, fr fr.
• nrid — the Number of RGID Values. literally just how many RGIDs are about to show up. it's giving headcount energy.
• chngc — the Change Count. the counter that tells you when things shifted. if she starts acting different, this is the field that snitched. 😭
• rac — the Reachability Association Characteristics. the vibe check field, basically. the traits of this association, all packed into one byte.
• rsvd17 — Reserved. not for you. not for me. reserved. hands off, bestie. 🙈
• rgid — the Reachability Group Identifier List. the flexible array hanging off the end, holding all the RGID values. she's the <italic>[]</italic> at the bottom and she's thriving. 🌈

---

quick note bestie: a few of these fields hang out in little arrays and reserved padding, so always respect the exact layout above. the struct said what she said. 💯

and that's the whole page, no crumbs left behind. this lil icon lives in the libnvme docs and got her glow-up in July 2026 — so if you're reading this later than that, hi, you're in the right place, mwah 🫶💜
