🦋 libnvme(9) — API Manual 🦋

okay so bestie, we're deep in the libnvme API manual and this page is all about one very specific little struct. no cap, it's giving "admin command response header" and we're gonna get into every field. 💅

💖 NAME 💖

struct nvme_mi_admin_resp_hdr — Admin command response header. 🎀

✨ SYNOPSIS ✨

here's the struct exactly as it shows up, bestie:

       struct nvme_mi_admin_resp_hdr {
           struct nvme_mi_msg_hdr hdr;
           __u8 status;
           __u8 rsvd0[3];
           __le32 cdw0, cdw1, cdw3;
        };

• hdr — Generic MI message header. it's the header part of the vibe. ✨
• status — Generic response code, and it's non-zero on failure. so yeah, pay attention to that one. 😭
• rsvd0 — Reserved. literally reserved, bestie, don't make it a main character. 🙈
• cdw0 — Completion Queue Entry doubleword 0. 👑
• cdw1 — Completion Queue Entry doubleword 1. 🌸
• cdw3 — Completion Queue Entry doubleword 3. yes, it's cdw3, keep it exactly like that. 💜

🌈 Description 🌈

so this is the generic response format with the three doublewords of completion queue data, plus optional response data. that's the whole tea. it's giving "structured response with optional extras" and honestly? iconic. 🫶
