nvme_mi_init_ctrl(2)

✨ nvme_mi_init_ctrl — a whole manual page, bestie edition ✨

okay so this one lives in the libnvme API manual and it's giving "let me introduce you to a controller" energy. section 2 vibes, obviously. let's get into it 🫶

---

💖 NAME 💖

nvme_mi_init_ctrl — initialise a NVMe controller.

like, that's it. that's the whole job. it's the "hey bestie, meet your controller" function. 🎀

---

🌸 SYNOPSIS 🌸

nvme_mi_ctrl_t nvme_mi_init_ctrl (nvme_mi_ep_t ep , __u16 ctrl_id );

two args in, one shiny controller object out. no cap. ✨

---

🦋 ARGUMENTS 🦋

• ep — the endpoint you wanna create this thing under. your home base, your launchpad, your little nest. 🪺
• ctrl_id — the ID of the controller to initialize. you gotta know which controller, bestie, you can't just vibe your way in. 💅

---

💜 DESCRIPTION 💜

so what this does: it creates a connection to a controller that lives behind the endpoint you passed in as ep. that's the whole thing. one endpoint in, one connection out. iconic behavior honestly. 👑

now, where do you get those controller IDs from, you ask? not from thin air, bestie 😭 — controller IDs may be queried from the endpoint through nvme_mi_mi_read_mi_data_ctrl_list. go look there, that's the plug. 🌈

also, like... when you're done? See nvme_mi_close_ctrl. close your doors, we're not leaving loose controllers lying around. cleanliness is main character energy. 🧚

---

⭐ RETURN ⭐

New controller object on success — slay, congrats, hug it, it's yours 💖

...or NULL on failure. 😭 in which case, no controller for you. sad little moment. check your args.

---

fr fr: the only NULL in this house is a failure. a valid nvme_mi_ctrl_t is never NULL. lowkey the most important thing on this page. 🔥

and that's the page!! written for the libnvme API manual, dated July 2026, titled nvme_mi_init_ctrl in section nvme_mi_init_ctrl(2) — yes the header and the footer said the same thing twice, we love a consistent queen 💅✨
