✨ NAME ✨

nvme_mi_admin_set_features_power_mgmt — Set power management feature 💅

okay so bestie, welcome to the libnvme API manual 🎀 this one's a little function that sets the power management feature, and honestly? it's giving "tiny function, big responsibilities" energy. let's get into it 🦋

---

🌸 SYNOPSIS 🌸

int nvme_mi_admin_set_features_power_mgmt (nvme_mi_ctrl_t ctrl , __u8 ps
, __u8 wh , bool save , __u32 *result );

like yes, it's a mouthful of a name, but the way that it just works? obsessed 💖

---

💫 ARGUMENTS 💫

• ctrl — the Controller to send command to. this is your main character, the one you're talking to 🫶
• ps — Power State. an __u8, so keep it smol and cute ✨
• wh — Workload Hint. also an __u8, also here to help 🌸
• save — a bool, and its whole deal is Save value across power states 👑 so if you want it to stick around, say yes fr fr
• result — a __u32 * and The feature data is returned in this argument 🍓 she's a pointer, she's writing back to you, she's literally the messenger

🦋 RETURN 🦋

so here's the tea: you get the nvme command status if a response was received — and yes, you should go peek at enum nvme_status_field for what those statuses actually mean, iykyk 👀

but if no response came back at all? it returns -1 with errno set instead. so like, check your errno, bestie, don't just stare at the -1 and hope for the best 😭

no cap: -1 means the whole thing fell through and errno is holding the receipts. read it. 💀
