LIBNVME_CTRL_GET_KXCHAP_CTRL_KEY-LIBNVME3(2)

📦 version 3.2, in arch rolling

💅 libnvme_ctrl_get_kxchap_ctrl_key — bestie, let's go get that key ✨

okay so real talk, this is a page straight out of the libnvme API manual, section 9, and it's about one very specific little getter: libnvme_ctrl_get_kxchap_ctrl_key. yes it's a mouthful, no you're not gonna say it out loud at a party. it just grabs the kxchap_ctrl_key for you. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

int libnvme_ctrl_get_kxchap_ctrl_key (const struct libnvme_ctrl *p ,
const char **kxchap_ctrl_key , const char *dflt );

look at her. three params, one int coming back. she's iconic, she's compact, she does exactly one thing. 🔥

🌸 ARGUMENTS 🌸

  • p — your struct libnvme_ctrl instance, i.e. the thing you're querying. this is the main character of the operation, ngl. 👑
  • kxchap_ctrl_key — this is where you want the value to land on success. it's a const char **, so like… you're handing over an address and she fills it in. slay. 💖
  • dflt — the value that gets stored in kxchap_ctrl_key when things go sideways. your lil safety net, your backup plan, your "if it doesn't work out we still have this" energy. 🫶

⭐ RETURN ⭐

she returns one of three things, and you gotta know which:

  1. 0 — success, we ate, everything is beautiful. 💅
  2. -ENOENT — the attribute does not exist. it's giving "you asked for something that isn't here." 😭
  3. a negative errno — some other failure happened. not the vibe, but at least she tells you. 💀
no cap, always check the return value. 0 is the only happy one, bestie — anything negative means the value in kxchap_ctrl_key is not what you're hoping for. 🙈

🦋 A LIL SIGN-OFF 🦋
