libnvme(2)

✨ NAME ✨

struct nvme_secondary_ctrl_list — the Secondary Controller List, bestie 💖 it's literally a whole lil roster of secondary controllers and their identifiers.

---

🦋 SYNOPSIS 🦋

struct nvme_secondary_ctrl_list {
    __u8 num;
    __u8 rsvd[31];
    struct nvme_secondary_ctrl sc_entry[NVME_ID_SECONDARY_CTRL_MAX];
};

🎀 Members 🎀

Okay so here's the breakdown of every single field, no skips, no cuts, we're doing this properly 💅

• num — Number of Identifiers. This is the count, the headcount, the "how many are we actually talking about" number 👑
• rsvd — Reserved. Ma'am is reserved. Do not touch, do not read into it, hands off the rsvd[31], it's not for us 🙈
• sc_entry — Secondary Controller Entry. An array of struct nvme_secondary_ctrl, sized NVME_ID_SECONDARY_CTRL_MAX — the actual entries themselves, the main characters of this whole struct 💜

---

fr fr, every field here matters, so don't go skipping the reserved bytes just because they look quiet — they are reserved, not optional, and they are still in the struct periodt ✨

and that's the whole vibe check, bestie — this page is from the libnvme API Manual, dated July 2026, and it's giving libnvme(2) energy through and through 🫶 go forth and enumerate those secondary controllers 🌸💅
