libnvme_get_subsys_attr(9)

✨ libnvme_get_subsys_attr ✨

okay so this is a page from the libnvme API manual bestie, and it's literally about reading one sysfs attribute off a subsystem 🎀 it's giving "small function, big main character energy" ngl

---

💅 NAME 💅

libnvme_get_subsys_attr — read a subsystem sysfs attribute

like, you hand it a subsystem, you tell it which attribute you want, and it goes and fetches the contents for you 🦋

---

🌸 SYNOPSIS 🌸

char * libnvme_get_subsys_attr (struct libnvme_subsystem *s , const char
*attr );

yep that's the whole vibe — pointer in, pointer out ✨

---

🫶 ARGUMENTS 🫶

• s — your struct libnvme_subsystem object, aka the subsystem you're being nosy about 👀
• attr — the sysfs attribute name, like the specific little file you want the tea from 🍓

---

💖 RETURN 💖

A newly allocated string holding the contents of attr — and yes bestie, the caller frees it, that's on you, no cap 😭

Or NULL in case of an empty value or an error 💀 so fr fr, check for that NULL before you go using it.

also like… remember to free() that string when you're done, because leaking memory is not the slay you think it is 🙈
