libnvme_sub...et_subsysnqn(9)

💅 libnvme_sub...et_subsysnqn(9) — the libnvme API manual, bestie edition

okay so picture this: you're deep in the libnvme API manual (libnvme_sub...et_subsysnqn(9), yes that's the whole title, it's giving truncated-in-the-header energy 😭) and you just need ONE tiny little string. That's this page. It's short, it's sweet, it ate, no notes. ✨

🌸 NAME 🌸

libnvme_subsystem_get_subsysnqn — bestie. it gets the subsysnqn. that's it. that's the whole job. 🎀

---

🦋 SYNOPSIS 🦋

const char * libnvme_subsystem_get_subsysnqn (const struct
libnvme_subsystem *p );

like literally just hand it a pointer and it hands you back a const char *. iconic behaviour fr fr. ✨

---

💖 ARGUMENTS 💖

• p — the struct libnvme_subsystem instance you wanna query. your little guy. your main character. 🫶

---

⭐ RETURN ⭐

it gives you back the value of the subsysnqn field — 💫 — or NULL if it's not set. so like, vibe check your pointer before you use it, ngl. NULL is not a valid string, it's the absence of one, and dereferencing it is a bad time. 💀

no cap: if this returns NULL, that field genuinely isn't set. don't go inventing a value, don't go printing it with %s, just check it. 🙈
