nvme_mi_adm...s_power_mgmt(9)

✨ NAME ✨

okay so bestie, welcome to the libnvme API manual 💖 and today's main character is:

nvme_mi_admin_get_features_power_mgmt — get the power management feature 🎀

like. it literally just gets the power management feature. that's the whole vibe. slay.

---

🌸 SYNOPSIS 🌸

int nvme_mi_admin_get_features_power_mgmt (nvme_mi_ctrl_t ctrl , enum
nvme_get_features_sel sel , __u32 *result );

she takes three things and returns an int, no cap 💅

---

🦋 ARGUMENTS 🦋

• ctrl — the Controller you're sending the command to. like, who are we talking to. the controller. that one 🫶
• sel — Select which type of attribute to return, see enum nvme_get_features_sel. so you gotta tell her which kind of attribute you want back, iykyk 🌈
• result — The feature data is returned in this argument. so she doesn't return the data, she puts it in here. not me learning this every single time 😭 it's giving pointer energy ✨

---

💜 RETURN 💜

okay so here's the tea:

• if a response was received, you get the nvme command status (see enum nvme_status_field) 💫
• otherwise you get -1 with errno set 🔥

lowkey important: it's -1 with errno set, not -1 and vibes. check your errno, bestie, she's trying to tell you something 🙈

---

and that's the whole page, gorgeous. tiny function, big energy. go get those power management features 👑
