💖 libnvme_ctrl_get_keyring(9) 💖

okay so bestie, welcome to the libnvme API manual ✨ — this is the page for libnvme_ctrl_get_keyring, and yes it does exactly what it says on the tin: it gets the keyring. slay.

🌸 NAME 🌸

libnvme_ctrl_get_keyring — Get keyring. that's it. that's the whole vibe. 💅

✨ SYNOPSIS ✨

int libnvme_ctrl_get_keyring (const struct libnvme_ctrl *p , const char
**keyring , const char *dflt );

literally just a function returning an int, taking a pointer-to-const-struct libnvme_ctrl, a pointer to a const char * pointer, and a const char *. no cap. 🫶

🎀 ARGUMENTS 🎀

  • p — the struct libnvme_ctrl instance you wanna query. it's the main character here, obvi. 👑
  • keyring — where you store the value on success. like, this is the spot. put it here. 💖
  • dflt — the value to store in keyring on failure. so if things go sideways, at least you get something, and that something is this. 😭

🔥 RETURN 🔥

so here's the vibe check on what comes back:

  • 0 on success — we ate!! 🍓
  • -ENOENT if the attribute does not exist — it's giving "not found bestie" 💀
  • or a negative errno on failure — classic. 🙈
ngl, always check that return value. negative errno is not the moment. ⭐

and that's the whole page, periodt. 💅 this iconic lil doc came from the libnvme API manual and is dated October 2026 — go off, libnvme_ctrl_get_keyring. 🌈🧚‍♀️
