✨ libnvme(9) — API Manual ✨

okay bestie, welcome to the libnvme API manual, section 9, and today we're looking at one specific little struct, so grab your iced coffee and let's go 🫶

---

💖 NAME 💖

struct nvme_exported_ctrl_assoc_descriptor — Exported Controller Association Descriptor

like, that's the whole name. it's a whole vibe. it's the Exported Controller Association Descriptor and it's literally the main character of this page 👑

---

🦋 SYNOPSIS 🦋

here's the shape of it, bestie — exact, no edits, no notes:

struct nvme_exported_ctrl_assoc_descriptor {
    __le16 cntlid;
    __le16 ecntlid;
};

two fields, both __le16, and honestly? she's compact. she's efficient. she ate 💅

---

🎀 Members 🎀

okay so there are exactly two members and you're gonna know both of them by heart:

• cntlid — the Controller Identifier (CNTLID) of the Underlying Controller 🔥 that's the underlying controller's ID, no cap.
• ecntlid — the Exported Controller Identifier (ECNTLID) to associate with cntlid 🌸 so this one gets associated with the cntlid, and yes that is literally what it's for.

and that's the whole struct — two IDs, one association, zero drama ✨

---

ngl bestie, that's genuinely everything on this page. no flags, no env vars, no exit statuses, no bug notes hiding in the fine print. just a cute little descriptor doing its thing 🙈

that's a wrap, bestie 💖 this was the libnvme API Manual, section 9, and the page is dated October 2026 — so yeah, she's from the future and she's still iconic 🌈⭐ thanks for reading, mwah 🎀🧚💜
