nvme_get_fe..._temp_thresh(2)

✨ nvme_get_features_temp_thresh ✨

okay bestie, welcome to the libnvme API manual 💖 this one lives in section 2 of the manual, and it's literally the cutest tiny little function whose entire job is asking your NVMe drive "hey girl, what's your temperature threshold? 🌡️"

---

🎀 NAME 🎀

nvme_get_features_temp_thresh — get the temperature threshold feature, no cap 🔥

---

🦋 SYNOPSIS 🦋

int nvme_get_features_temp_thresh (int fd , enum nvme_get_features_sel
sel , __u32 *result );

so it takes a file descriptor, a selector, and a pointer to a result, and it hands you back an int. that's it, that's the whole vibe ✨

---

🌸 ARGUMENTS 🌸

• fd — the file descriptor of your nvme device 🫶 that's your little portal to the drive, so obviously you need it.
• sel — which type of attribute you want back, okurrr? go peek at enum nvme_get_features_sel to see your options, iykyk 👑
• result — the command completion result from CQE dword0 💅 that's where the answer lands when the drive replies.

---

💜 RETURN 💜

if a response came back, you get the nvme command status — and yes, you should go check enum nvme_status_field to decode that lil guy 🔍

and if things went sideways? you get -1 and errno gets set. it's giving "we don't know her" energy, but that's just how errors work, not me being dramatic 😭

---

⚠️ real talk: -1 is the failure signal here, and errno is doing the emotional labor of telling you why. always check it, bestie, fr fr 🍓

---

🌈 SEE ALSO 🌈

• enum nvme_get_features_sel
• enum nvme_status_field

both of those were already name-dropped up in ARGUMENTS and RETURN because they're literally load-bearing, so go read them if you want the full tea 🧚

okay that's the whole page!! it's short, it's sweet, it's iconic, it ate and left no crumbs 💅
