NVME_SET_FEATURES_TIMESTAMP(2)

✨ nvme_set_features_timestamp — the libnvme API manual, bestie edition ✨

okay so picture this: it's the libnvme API manual and we're doing nvme_set_features_timestamp(2). yeah she's a whole syscall-wrapper vibe and honestly? iconic. let's get into it 🎀

---

💖 NAME 💖

nvme_set_features_timestamp — set that timestamp feature, periodt ⏰✨

---

🦋 SYNOPSIS 🦋

int nvme_set_features_timestamp (int fd , bool save , __u64 timestamp );

look at her. three little arguments. no cap, that's the whole signature 💅

---

🌸 ARGUMENTS 🌸

• fd — the file descriptor of your nvme device. literally the doorway to the drive, bestie 🚪✨
• save — save the value across power states. yes girl, make it persistent 💾
• timestamp — the current timestamp value you wanna assign to this feature. it's a __u64, so big numbers are welcome here 👑

---

🫶 RETURN 🫶

so here's what comes back at you:

• the nvme command status if a response was received — peek at enum nvme_status_field for the deets 🔍
• otherwise it's -1 with errno set. sad girl hours, but at least you know why 😭

---

ngl bestie, always check that return value before you celebrate. -1 is giving "we need to talk" 💀
