NVME_GET_FEATURES_LBA_RANGE(2)

💖 nvme_get_features_lba_range 💖

okay bestie, so this one lives in the libnvme API manual, and honestly? It's giving legacy. Let's get into it 🎀

---

✨ NAME ✨

nvme_get_features_lba_range — grab the LBA range feature, that's the whole job 💅

---

✨ SYNOPSIS ✨

int nvme_get_features_lba_range (int fd , enum nvme_get_features_sel sel
, struct nvme_lba_range_type *data , __u32 *result );

like yes she's a function, yes she takes four things, yes she's lowkey deprecated (we'll get there 🙈)

---

🌸 ARGUMENTS 🌸

• fd — the file descriptor of your nvme device. that's your whole entire connection to the drive, do not lose her 🫶
• sel — tells it which type of attribute to return. options live in enum nvme_get_features_sel, go look 👀
• data — the user address of the feature data, if applicable. like, only if it applies, bestie, no pressure ✨
• result — the command completion result from CQE dword0. that's where the tea comes back to you 🍓

---

💀 DESCRIPTION 💀

Deprecated: doesn't support specifying a NSID. Use nvme_get_features_lba_range2 instead.

not me having to tell you this 😭 she's deprecated, periodt. The one thing she cannot do — literally cannot — is let you specify an NSID. So if that's what you need (and it probably is), go use nvme_get_features_lba_range2 instead. She ate, but her time has passed 👑

---

⭐ RETURN ⭐

You get back the nvme command status if a response was received — peek at enum nvme_status_field for the deets. If not? You get -1, with errno set otherwise. So check that errno, girlie, she's trying to tell you something 💜

---

that's the whole page, no skips, no crumbs left behind ✨

cute lil sign-off time: this gem comes from the libnvme API manual, dated July 2026. mwah 💋
