nvme_identify_nvmset_list(2)

💖 nvme_identify_nvmset_list — bestie edition 💖

okay so this is a page from the libnvme API manual, section 2, and it's about one very specific little function that goes and gets you a list. a whole list. a NVM Set List, to be exact. and honestly? it's giving "quietly essential." 🦋

✨ NAME ✨

nvme_identify_nvmset_list — retrieves the NVM Set List, no cap

---

🌸 SYNOPSIS 🌸

int nvme_identify_nvmset_list (int fd , __u16 nvmsetid , struct
nvme_id_nvmset_list *nvmset );

---

🎀 ARGUMENTS 🎀

• fd — the file descriptor of your nvme device. like, your in. your connection. your little doorway into the drive. 💅
• nvmsetid — the NVM Set Identifier. this is the whole point of the function, lowkey. it's what you're starting from. 🌟
• nvmset — the user space destination address where the data gets transferred. basically, "bestie, here's a spot, please put the stuff there." 🫶

---

🦋 DESCRIPTION 🦋

So like. This function retrieves an NVM Set List, which comes back as a struct nvme_id_nvmset_list. 🎀

And here's the cute part — the data structure is an ordered list by NVM Set Identifier, starting with the first NVM Set Identifier supported by the NVM subsystem that is equal to or greater than the NVM Set Identifier. So it's not just vibes, it's ordered vibes. >= energy. 🔥

If you wanna see the definition of the returned structure, go look at struct nvme_id_nvmset_list. That's the blueprint. 📜

---

⭐ RETURN ⭐

This is the part where we find out how it went:

• If a response was received, you get the nvme command status — peep enum nvme_status_field for the deets.
• Otherwise you get -1 with errno set. 😭 that's the "it didn't go" path. check your errno, bestie, it's literally telling you what happened.

no response? no status. just -1 and an errno staring back at you. read it. 🙈

and that's the whole page, periodt. 💜 this came out of the libnvme API manual, dated July 2026 — go forth and identify those NVM sets, you beautiful main character. 👑💖
