nvme_get_features_simple(2)

💖 nvme_get_features_simple(2) 💖

okay bestie, this one lives in the libnvme API manual, and it's literally the chill little shortcut you call when you want the basic stuff without doing the whole song and dance. sit down, it's short but it's important 🫶

---

✨ NAME ✨

nvme_get_features_simple — Helper function for @nvme_get_features()

---

🌸 SYNOPSIS 🌸

int nvme_get_features_simple (int fd , enum nvme_features_id fid , __u32
nsid , __u32 *result );

---

🎀 ARGUMENTS 🎀

• fd — File descriptor of nvme device. like, your ✨entry pass✨ to the device, bestie.
• fid — Feature identifier. which feature are we asking about? this tells it 🦋
• nsid — Namespace ID, if applicable. only relevant sometimes — "if applicable" is doing a lot of work here ngl 💅
• result — The command completion result from CQE dword0. the tea. the actual answer lands in here 👑

---

⭐ RETURN ⭐

The nvme command status if a response was received (see enum nvme_status_field), or -1 with errno set otherwise. so basically: you either get a status, or a -1 with errno telling you what went wrong 😭 no in-between, it's giving very much one or the other.

not me reminding you to check errno when you get that -1 🙈 the status enum is over in enum nvme_status_field if you need the lore.

and that's the whole page, periodt 💜 this little helper is part of the libnvme API manual, dated July 2026, and it's the version where nvme_get_features_simple and nvme_get_features_simple(2) are basically holding hands in the footer. slay 🎀✨
