💅 libnvme_ctrl_get_cntlid — bestie's guide to grabbing a cntlid

okay so this is a page from the libnvme API manual, and it's literally just one little function that fishes a cntlid out for you. tiny function, big main character energy. let's get into it 🫶

✨ NAME ✨

libnvme_ctrl_get_cntlid — get that cntlid. that's it. that's the whole job. 💖

🌸 SYNOPSIS 🌸

int libnvme_ctrl_get_cntlid (const struct libnvme_ctrl *p , const char
**cntlid , const char *dflt );

three args, one int back. lowkey adorable ngl 🎀

🦋 ARGUMENTS 🦋

  • p — the struct libnvme_ctrl instance you're querying. your little controller bestie 💜
  • cntlid — where you want the value stashed on success. like, hand it a spot and it'll fill it in ✨
  • dflt — the value to store in cntlid if it fails. your fail-safe, your backup plan, your emotional support default 🙈

🔥 RETURN 🔥

  • 0 on success — slay, you got it 👑
  • -ENOENT if the attribute does not exist — it's giving "not found bestie" 💀
  • or a negative errno on failure — something went sideways, check your errno 😭
no cap, those are the only three outcomes. memorize them, they will come up iykyk ⭐

and that's the whole page!! short and iconic, honestly. this little number comes to you from the libnvme API manual, dated October 2026, filed under libnvme_ctrl_get_cntlid — go off, you understood the assignment 🧚💖🌈
