NVME_GET_FEATURES_POWER_MGMT(2)

✨ NAME ✨

nvme_get_features_power_mgmt — okay bestie, this one grabs the power management feature for you 💅

It's a lil function from the libnvme API manual, section 2, and she is so useful, no cap 🫶

---

🌸 SYNOPSIS 🌸

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

Like… that's the whole vibe. Three little things go in, an int comes out 🎀

---

🦋 ARGUMENTS 🦋

• fd — the file descriptor of your nvme device, bestie. Your lil passport to the drive 🪪✨
• sel — which type of attribute you want back. Go check enum nvme_get_features_sel for the menu, it's giving ✨build-your-own-feature✨ 🍓
• result — the command completion result, straight outta CQE dword0 👑 (yes, dword0. she's iconic like that.)

---

💖 RETURN 💖

So here's what you get back, fr fr:

The nvme command status if a response was received — peep enum nvme_status_field for the full deets on what that status could be 👀

…or -1 with errno set, if it's not that 💀 (otherwise, as the elders say)

---

lowkey important: it's either a real status code OR a -1 + errno situation. There is no third option, periodt 💅
