💖 libnvme(9) — like, the API Manual, bestie 💖

Okay so gather round, because today we're looking at a tiny little struct that lives in the API Manual and it's honestly such a vibe. It's giving "small but mighty" and I'm obsessed. 🫶

---

✨ NAME ✨

struct nvme_id_iocs — the NVMe Identify IO Command Set data structure. Yes, that's the whole name, and yes she ate. 👑

---

🌸 SYNOPSIS 🌸

Here's the whole thing, fr fr — no cap, this is literally all of it:

struct nvme_id_iocs {
    __le64 iocsc[512];
 };

That's it. That's the struct. Main character energy in like four lines. 💅

---

🦋 Members 🦋

• iocsc — the list of supported IO Command Set Combination vectors. Lowkey the whole personality of this struct ngl. It's a __le64 array of 512, and it's holding all the supported combos for you. Iconic. ⭐

---

Real talk though bestie: the values in iocsc are little-endian (__le64), so don't go reading them raw on a big-endian machine unless you enjoy chaos. 😭 That's just what the type says — the manpage told me, I'm just passing it along. 💀

---

And that's the page! Short, sweet, and to the point — much like struct nvme_id_iocs herself. 🌈

Hope that cleared things up, bestie — go forth and identify those IO Command Sets. 🧚💜
