nvme_mi_adm...allocated_ns(2)

✨ nvme_mi_admin_identify_allocated_ns — the "who dis" for an allocated namespace ✨

okay bestie, real talk: this one lives in the libnvme API manual, it's a function in the <purple>libnvme</purple> family, and its whole vibe is asking a namespace "so... what ARE you?" 💅

No cap, the name is a whole mouthful — nvme_mi_admin_identify_allocated_ns — but it's giving very main character once you know what it does. Let's get into it. 🦋

---

🌸 SYNOPSIS 🌸

int nvme_mi_admin_identify_allocated_ns (nvme_mi_ctrl_t ctrl , __u32
       nsid , struct nvme_id_ns *ns );

Yes that's the exact signature, character for character, don't @ me. 💖

---

🎀 ARGUMENTS 🎀

• ctrl — the Controller you're sending this identify command through. It's the one holding the AUX cord. 🔌
• nsid — the namespace ID. Which namespace are we snooping on? This one. 👀
• ns — the namespace identification struct you want populated. It goes in empty-ish and comes out ✨informed✨.

---

👑 DESCRIPTION 👑

Perform an Identify (namespace) command, and set the namespace id data into ns.

That's the whole thing, bestie — it literally runs an Identify (namespace) command and drops the namespace ID data into your ns struct. It's giving "hi, please fill out this form" but make it NVMe. 📋✨

💀 RETURN 💀

Here's the important part, fr fr:

• If a response came back, you get the nvme command status (peep enum nvme_status_field for the deets on what those statuses mean).
• Otherwise you get -1 and errno is set. 😭

not the -1... if you see that, go check errno immediately, that's your clue, iykyk 🔍

that's the whole page angel, no filler, all facts, periodt 💅🫶
