💖 NAME 💖

ok so bestie, welcome to the libnvme_mi_mi_read_mi_data_ctrl page — it's a straight-up Read MI Data Structure command that pulls controller info for you. that's the whole vibe. 🎀

(this is from the libnvme API manual, btw — like, that's the family it belongs to ✨)

---

🌸 SYNOPSIS 🌸

int libnvme_mi_mi_read_mi_data_ctrl (struct libnvme_mi_ep *ep , __u16 ctrl_id , struct nvme_mi_read_ctrl_info *ctrl );

---

🦋 ARGUMENTS 🦋

• ep — your endpoint for MI communication, like the little phone line the two of you are talking on 📞
• ctrl_id — the ID of the controller you wanna query, iykyk 👑
• ctrl — the controller data you're gonna populate, like a little empty cup waiting to be filled 🍓

---

✨ DESCRIPTION ✨

It retrieves the Controller Information Data Structure for the attached controller with ID ctrlid. no cap, that's literally its whole job 💅

also, go peep struct nvme_mi_read_ctrl_info — that's where the tea lives 🫖

🔥 RETURN 🔥

So what comes back? Either:

• the nvme command status if a response was received (check enum nvme_status_field for the deets), or
• a negative error code otherwise 😭

fr fr, negative error code = something went sideways, bestie. handle it, don't ghost it 💀
