nvme_ctrl_reset(2)

💖 nvme_ctrl_reset(2) 💖

okay bestie, welcome to the libnvme API manual ✨ this one's short and sweet and honestly kinda iconic. we're resetting a controller. that's it. that's the whole vibe. 🎀

---

✨ NAME ✨

nvme_ctrl_reset — Initiate a controller reset 💅 like, you're telling the NVMe controller to go take a little nap and come back recharged.

---

✨ SYNOPSIS ✨

int nvme_ctrl_reset (int fd );

one function, one argument, zero drama. 🦋

---

✨ ARGUMENTS ✨

• fd — File descriptor of nvme device 🫶 the little handle you got when you opened the thing. hold onto it. love it. pass it here.

---

✨ DESCRIPTION ✨

okay so real talk: This should only be sent to controller handles, not to namespaces. 👑

that's the whole rule, and it's non-negotiable. controller handles get the reset. namespace handles do NOT. do not pass your namespace fd here, we are not doing that today, i will find out 😭

think of it like — the controller is the whole group chat, and the namespaces are just the individual threads. you reset the group chat, not one thread. it's giving top-down energy 🌈💀

---

✨ RETURN ✨

• 0 — a reset was initiated 🎉 slay, you did it, the controller is off doing its little reset ritual, go you 💖
• -1 — with errno set otherwise 🙈 something went sideways, check your errno, it'll tell you the tea.

---

⚠️ reminder bestie: this goes to controller handles only. namespace handles are a hard no. no cap. 🚫

so yeah, that's nvme_ctrl_reset. tiny page, big power moves. July 2026 era, straight out of the nvme_ctrl_reset corner of the libnvme API manual — she's been serving these exact semantics since forever and she's never once missed. periodt. 💜🌸✨
