libnvme(9)

💅 libnvme(9) — the API Manual, bestie edition 🎀

Okay so this is a page from the libnvme API Manual, and it's literally just one little enum, but it's an important little enum, so let's get into it ✨

---

🦋 NAME 🦋

enum nvme_mi_dtyp — the Data Structure Type field. That's it. That's the whole name. Short, sweet, iconic 👑

---

🌸 SYNOPSIS 🌸

Here's the whole thing, verbatim, no edits, no cap:

enum nvme_mi_dtyp {
    nvme_mi_dtyp_subsys_info ,
    nvme_mi_dtyp_port_info ,
    nvme_mi_dtyp_ctrl_list ,
    nvme_mi_dtyp_ctrl_info ,
    nvme_mi_dtyp_opt_cmd_support ,
    nvme_mi_dtyp_meb_support

};

Six constants, in that order, with that trailing comma energy. Slay 💅

---

✨ Constants ✨

These are the six values, and ngl each one is doing its own little job. Here's the rundown:

• nvme_mi_dtyp_subsys_info — NVM Subsystem Information. The big-picture subsystem tea 🫖
• nvme_mi_dtyp_port_info — Port information. All the port deets 🔌
• nvme_mi_dtyp_ctrl_list — Controller List. A whole list of controllers, bestie 📋
• nvme_mi_dtyp_ctrl_info — Controller Information. The controller's whole lore 🧚
• nvme_mi_dtyp_opt_cmd_support — Optionally Supported Command List. The commands that are like "maybe, depends" — optional girlies 💁
• nvme_mi_dtyp_meb_support — Management Endpoint Buffer Command Support List. Long name, big main-character energy 👑

---

💖 Description 💖

So what is this thing? It's the Data Structure Type field for the Read NVMe-MI Data Structure command. Basically it tells the endpoint which particular structure you wanna query from it — like pointing at the menu and going "that one, please" 🍓

That's the entire vibe check: pick a constant, ask the endpoint for that structure, done. Periodt ✨

💀 Real talk though: this page is just the enum definition and the meaning of each constant. There's no extra lore here, so don't go looking for it — everything you need is up above, fr fr.

and that's the whole page, bestie 🌈 This absolute gem landed in the libnvme manual as enum nvme_mi_dtyp, dated October 2026, and it's signed off with the source/version tag libnvme(9) — so if anyone asks where you got your Data Structure Type info, you say libnvme, October 2026, and you say it with your chest 💜🫶
