✨ nvme_set_features_hctm ✨

okay bestie, welcome to the libnvme API manual for nvme_set_features_hctm(2) — yes the title is doing the absolute most, it's literally the same name three times. anyway. this one's about setting the thermal management feature on your NVMe device, and honestly it's giving "I run hot" energy but make it firmware. 💅

🎀 ARGUMENTS 🎀

• fd — File descriptor of nvme device. this is your ticket in, your little backstage pass to the drive. 🎟️
• tmt2 — Thermal Management Temperature 2. the second temperature. yes there are two of them. the girlies love a sequel. 🌡️
• tmt1 — Thermal Management Temperature 1. the original temperature, the blueprint, the main character. 💖
• save — Save value across power states. so if you set this, your setting survives the drive going night-night and waking back up. persistence queen. 👑
• result — The command completion result from CQE dword0. that's where the answer comes back and lands. 🦋

🔙 RETURN 🔙

it hands you the nvme command status if a response was received — go peek at enum nvme_status_field for the full tea — or it gives you -1 with errno set if things went sideways. 🫠

---

ngl, always check that return value. -1 is not a vibe, it's an error, and errno is the friend who tells you what actually happened. 💀

that's the whole page bestie, no filler, no gatekeeping. this was the nvme_set_features_hctm page from the libnvme API manual, and the version in question is dated July 2026, footer-shaped like nvme_set_features_hctm nvme_set_features_hctm(2). slay, stay cool (literally, that's what this function is for), and go read some more manpages. bye babes 💜✨🎀
