libnvmf_tid_get_subsysnqn(9)

πŸ“¦ version 3.2, in arch rolling

πŸ’… libnvmf_tid_get_subsysnqn β€” from the libnvme API manual, bestie

Okay so real talk, this one is a tiny little function but it's genuinely iconic in a "small but mighty" way. It lives in the libnvme API manual β€” section 9, kernel/API territory β€” and it's literally just here to hand you a string. That's it. That's the whole vibe. πŸŽ€


✨ NAME ✨

libnvmf_tid_get_subsysnqn β€” get the subsysnqn. No cap, that's the entire description. It's giving "does exactly what it says on the tin" energy. 🫢


✨ SYNOPSIS ✨

const char * libnvmf_tid_get_subsysnqn (const struct libnvmf_tid *p );

Look at that signature. const char * return, const struct libnvmf_tid * argument β€” nobody's mutating anything here, it's all read-only, respectful, boundary-having code. πŸ‘‘


✨ ARGUMENTS ✨

  • p β€” the struct libnvmf_tid instance you want to query. This is your main character right here, bestie β€” you hand it over and it tells you what you need to know. πŸ”

✨ RETURN ✨

It returns the value of the subsysnqn field. Slay. πŸ’–

But heads up, because this is the part you actually need to remember: if that field isn't set, you get NULL back. So like… check it before you go dereferencing it, okay? Do not be out here treating NULL like a valid string, that's a one-way ticket to segfault city and nobody wants that. 😭

Lowkey the whole API is just one getter. Highkey the whole API is just one getter. Either way, check for NULL. πŸ’€

And that's the tea, bestie πŸ“ β€” this page is from the libnvme API manual, version date October 2026, and honestly? She understood the assignment. Go get that subsysnqn. πŸ’…βœ¨
