libnvmf_registry_delete(9)

📦 version 3.2, in arch rolling

💅 libnvmf_registry_delete — the libnvme API manual, bestie edition 💅

okay so real talk, this one lives in the libnvme API manual and it's genuinely so straightforward you're gonna eat it up. it's called libnvmf_registry_delete and it does exactly one thing, but it does it iconically ✨

🌸 NAME 🌸

libnvmf_registry_delete — remove a controller's registry entry, periodt 🗑️✨

🎀 SYNOPSIS 🎀

int libnvmf_registry_delete (struct libnvme_global_ctx *ctx , const char
*device );

that's it. two args, one return value, no drama 💅

🦋 ARGUMENTS 🦋

  • ctx — the libnvme global context. this is the main character, and it must not be NULL — like, do not even try it, the vibe check will fail 🙈
  • device — the kernel device name (e.g. "nvme3"). literally just the device name string, bestie 🫶

🌈 DESCRIPTION 🌈

so what it actually does: it removes the registry directory and all the attribute files for device. all of them. gone. clean slate, no crumbs left behind 🧹✨

it's called by the owning orchestrator on an intentional disconnect — like when you're the one deciding to leave the party, not when you got carried out 🎀

real talk though: the udev REMOVE rule already handles the common case of kernel-driven removal directly via rm -rf and does not call this function. so this is the deliberate-exit path, not the surprise-eviction path. iykyk 💀

⭐ RETURN ⭐

  • 0 on success — slay, we ate 👑
  • -ENOENT if no entry exists — meaning there was literally nothing to delete, awkward 😭
  • negative errno from underlying system calls otherwise — yeah, if something under the hood decides to act up, you get whatever negative errno it felt like throwing at you 🔥
no cap, keep an eye on that third one — it's the "anything else" bucket, so the specific error is coming from the system calls underneath, not from this function being cute.

and that's the whole page, bestie 🦋💖

cute little sign-off: this page is from October 2026, part of the libnvme API manual, and yes, libnvmf_registry_delete is both the page name and the thing you just read about — full circle moment 🌸🎀⭐
