💖 nvme_get_features_auto_pst(2) 💖

okay so bestie, welcome to the libnvme API manual 🌸 this one's all about grabbing the autonomous power state feature off your NVMe device. yes, autonomous. yes, power. it's giving self-sufficient energy management 👑

---

✨ NAME ✨

nvme_get_features_auto_pst — Get autonomous power state feature 🦋

---

✨ SYNOPSIS ✨

int nvme_get_features_auto_pst (int fd , enum nvme_get_features_sel sel
, struct nvme_feat_auto_pst *apst , __u32 *result );

like, four arguments, one int, no drama 💅

---

✨ ARGUMENTS ✨

• fd — File descriptor of nvme device 🔥 this is the whole "which drive are we talking to" situation.
• sel — Select which type of attribute to return, see enum nvme_get_features_sel ✨ you literally pick the flavor of attribute you want back.
• apst — so… the original manual page has literally no description here 🙈 like, blank. nothing. empty. I'm not gonna make something up about it because that would be lying to you and we don't do that in this group chat. It's there, it's a struct nvme_feat_auto_pst *, and the manpage said nothing else. periodt.
• result — The command completion result from CQE dword0 👑 that's the lil value the controller hands back when it's done.

---

✨ RETURN ✨

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

fr fr, if you get -1 go check errno, that's where the tea is ☕
