libnvme_ctrl_get_subsysnqn(9)

✨ libnvme_ctrl_get_subsysnqn ✨

okay so bestie, welcome to the libnvme API manual 💅 this one is a tiny lil function page and honestly it's giving "short but essential" — it's libnvme_ctrl_get_subsysnqn, and yes she's a section 9 girly (kernel/API vibes, iykyk).

---

🔍 NAME

libnvme_ctrl_get_subsysnqn — get subsysnqn 🎀

Like, that's literally her whole job. She gets the subsysnqn. No cap.

---

🦋 SYNOPSIS

const char * libnvme_ctrl_get_subsysnqn (const struct libnvme_ctrl *p );

Copy it exactly like that, bestie — spacing and all, don't be creative with code 💀

---

🌸 ARGUMENTS

• p — the struct libnvme_ctrl instance you're querying 👑 this is the controller you're like... asking about. She needs to know which one, so hand her the pointer, mwah.

---

💖 RETURN

The value of the subsysnqn field, or NULL if it's not set 🫶

so like — if you get NULL back, that's not a crash, that's just the function being honest with you: nothing's set. vibe check passed, but the field is empty, fr fr.

---

🌈 that's it, that's the page

no hidden lore, no extra flags, no environment variables — she's a one-job icon and she ate ✨

made with love (and a genuinely alarming amount of struct knowledge) — this was the libnvme API manual, October 2026 edition 🎀 go forth and query your controllers, bestie 💜🦋
