nvme_get_attr(2)

✨ nvme_get_attr — bestie's guide to reading a sysfs attribute ✨

okay so you're in the libnvme API manual for the nvme_get_attr(2) page, and honestly? this one is short and sweet and you're gonna eat 💅

---

🌸 NAME 🌸

nvme_get_attr — literally just: Read sysfs attribute. that's it. that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

char * nvme_get_attr (const char *d , const char *attr );

yes bestie, that's a char * coming back at you. hold onto it. 🎀

---

💖 ARGUMENTS 💖

• d — the sysfs directory, fr fr. it's a const char * and it's telling you where to look.
• attr — the sysfs attribute name, also a const char *. this is the what to look at. 👑

---

🔥 RETURN 🔥

so like, what do you actually get back? you get a string with the contents of attr, periodt. 💫

but hear me out — you can also get NULL. and that happens in two situations, no cap:

• when the value is, like, empty 🙈
• when there's an error — and that error is indicated by a non-zero errno code, so go check errno, bestie, don't just stand there 😭

---

ngl, the NULL case is the main character here. always check it. always. 💀
