libnvme(2)

💖 libnvme(2) — the manual page, bestie edition 💖

okay so you're in the libnvme manual, section 2, and today we're talking about one very specific little struct. she's small, she's iconic, she's the MI response message header. let's get into it 🎀

---

✨ NAME ✨

struct nvme_mi_mi_resp_hdr — the MI response message header. that's her. that's the whole name. short, sweet, slays 💅

---

🌸 SYNOPSIS 🌸

struct nvme_mi_mi_resp_hdr {
    struct nvme_mi_msg_hdr hdr;
    __u8 status;
    __u8 nmresp[3];
 };

look at her. three little members. a whole personality. 🦋

---

👑 Members 👑

• hdr — the generic MI message header. like, the standard issue one everybody gets. it's giving base layer ✨
• status — the generic response status from the command. lowkey the most important one ngl: if this is non-zero, that means failure. so if you're checking this and it's not zero, something went wrong, and you should be paying attention, fr fr 😭
• nmresp — the NVMe Management Response. this is the command-type-specific response data. so like, whatever command you sent, this is the part that answers back in its own special way. bespoke. tailored. main character energy 👑

---

💜 Description 💜

so this whole struct is the wire format for the MI response message header, and it's defined in section 5 of NVMe-MI. that's it, that's the lore. iykyk 🌈

if you're out here parsing bytes off a wire and you need to know what the response header looks like — this is the shape. don't guess, don't improvise, just use the format. periodt 💅

⚠️ friendly reminder bestie: that status field is non-zero on failure. don't just vibe past it. check it. your future self will thank you 🫶

and that's the page!! this was struct nvme_mi_mi_resp_hdr</p> from the libnvme API Manual, born July 2026, and yes the footer really does just say the struct name and libnvme(2) like a little signature. obsessed with the consistency honestly. go forth and parse responsibly, bestie 💖✨🎀
