✨ nvmf_connect_io_queue(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — it's nvmf_connect_io_queue(9), and it's literally the NVMe Fabrics I/O Queue "Connect" API function 💅

---

🎀 NAME 🎀

nvmf_connect_io_queue — the NVMe Fabrics I/O Queue "Connect" API function. that's it, that's the vibe 🦋

---

🧚 SYNOPSIS 🧚

int nvmf_connect_io_queue (struct nvme_ctrl *ctrl , u16 qid );

---

🌸 ARGUMENTS 🌸

• ctrl — this is your host nvme controller instance, and its whole job is to establish an NVMe I/O queue connection to the already allocated NVMe controller over on the target system 🫶
• qid — the NVMe I/O queue number for the brand-new I/O connection between host and target. but heads up bestie, qid == 0 is illegal because that one is the Admin queue, per the NVMe standard 💀 like don't even try it

---

💖 DESCRIPTION 💖

so what this function does is it issues a fabrics-protocol connection of an NVMe I/O queue — and it does it via the NVMe Fabrics "Connect" command — between the host system device and the allocated NVMe controller on the target system. that's the whole main character moment, no cap ✨👑

---

🌈 RETURN 🌈

• 0 — success, we ate 🍓
• > 0 — NVMe error status code 😭
• < 0 — Linux errno error code 🙈
