nvme_lookup_keyring(2)

✨ nvme_lookup_keyring ✨

okay bestie, so this is a page from the libnvme API manual, section 2 (that's the syscall/function girlies 💅). It's giving very short, very sweet, very "one job and she does it" energy. Let's get into it 🫶

---

💖 NAME 💖

nvme_lookup_keyring — Lookup keyring serial number

🌸 SYNOPSIS 🌸

long nvme_lookup_keyring (const char *keyring );

🎀 ARGUMENTS 🎀

• keyring — the Keyring name. That's it. That's the whole input. She takes a name and she goes looking 👀

🦋 DESCRIPTION 🦋

So basically, nvme_lookup_keyring looks up the serial number of the keyring you handed it in keyring. You give her a name, she comes back with the serial number. No cap, that's the entire plot 💖

⭐ RETURN ⭐

You get back the key serial number of the keyring — slay ✨

But if it can't do that, you get 0 back with errno set. So like, zero is not a vibe here, it's the "something went wrong" flag, and errno is the little note she leaves explaining what happened 🙈

⚠️ bestie listen: if you see 0, don't go assuming there's a keyring with serial number zero. Check errno. Periodt.

and that's the whole page, iconically short, we love a low-effort queen 👑
