nvme_get_features_hctm(2)

💅 nvme_get_features_hctm — it's giving libnvme API manual energy 👑

Ok so bestie, welcome to nvme_get_features_hctm(2), straight outta the libnvme API manual. Yes this is a whole manpage, and yes we're gonna make it cute. Let's go. 🦋

✨ NAME ✨

nvme_get_features_hctm — Get thermal management feature

Like, it gets the thermal management feature. That's the whole job. She's focused, she's employed, she's serving. 🌡️💖

---

🌸 SYNOPSIS 🌸

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

There she is. Three little arguments and a dream. Periodt.

---

🎀 ARGUMENTS 🎀

• fd — File descriptor of nvme device. Lowkey your all-access pass to the drive, the VIP wristband, the ✨source of truth✨. No fd, no vibes.
• sel — Select which type of attribute to return, see enum nvme_get_features_sel. It's literally the "which flavor do you want" dropdown. Go look at the enum, the enum is right there, iykyk. 🍓
• result — The command completion result from CQE dword0. Just a __u32 * where the answer gets dropped off, like a little gift from the completion queue. No cap.

---

🔥 RETURN 🔥

• The nvme command status if a response was received (see enum nvme_status_field), or
• -1 with errno set otherwise.

So basically: you get a status, or you get -1 and errno is screaming at you from the other room. Check the enum, bestie, don't ignore the enum. 💀 (affectionately)

Fr fr though — that error path is real. -1 means it's ✨not✨ giving, and errno is the group chat explaining why.

---

Anyway, that's the whole page! She's short, she's iconic, she does exactly one thing and does it flawlessly — main character energy only 💜

Sign-off time 🫶: this was the nvme_get_features_hctm page from the libnvme API manual, dated July 2026, and the source/version footer said nvme_get_features_hctm on both sides. Slay, bye! ✨🌈🎀
