💖 nvme_get_features_kato(2) 💖

okay bestie, we're in the libnvme API manual and this one is chef's kiss — it's all about getting the keep alive timeout feature from your NVMe device. yes, the thing that keeps the vibes alive between you and your drive. 🫶

✨ NAME ✨

nvme_get_features_kato — get the keep alive timeout feature, periodt.

---

🌸 SYNOPSIS 🌸

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

---

🎀 ARGUMENTS 🎀

• fd — the file descriptor of your nvme device. like, your little VIP pass to the drive. 💅
• sel — which type of attribute you wanna be returned to you, bestie. check enum nvme_get_features_sel for the deets. it's giving "choose your own adventure". 🌈
• result — the command completion result from CQE dword0. yes, dword0, exactly, don't come for me, that's what it is. 💀

---

⭐ RETURN ⭐

the nvme command status if a response was received (peep enum nvme_status_field for that whole situation), or -1 with errno set otherwise. so either you got the tea, or you got -1 and a lil error code to go with it. 😭

no cap: if you see the -1, go check that errno, she's trying to tell you something.
