NVME_GET_FEATURES_ERR_RECOVERY(2)

💖 nvme_get_features_err_recovery — bestie edition 💖

okay so this is a little function from the libnvme API manual, section 2 (that's the syscall/library-functions girlies 💅). buckle up, it's a short one but it's got ✨lore✨.

---

🌸 NAME 🌸

nvme_get_features_err_recovery — get the error recovery feature 👑 lowkey iconic

---

🎀 SYNOPSIS 🎀

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

like. it takes three things. that's it. that's the whole vibe 🦋

---

✨ ARGUMENTS ✨

• fd — the file descriptor of your nvme device 🫶 the lil handle that says "yes hello, this drive right here"
• sel — which type of attribute you want back, fr fr. it's a enum nvme_get_features_sel situation, so go look at that enum for your options
• result — the command completion result, straight from CQE dword0 💀 yes that's really what it says. that's where the answer lands

---

💀 DESCRIPTION 💀

so. um. Deprecated. not me having to tell you this 😭

it doesn't support specifying a NSID. that's the whole problem. that's the tea. 🍓

use nvme_get_features_err_recovery2 instead — she's the upgraded version, she supports the NSID, she ate 💅✨

bestie if you're writing new code, please don't reach for this one. i'm not mad, i'm just disappointed 🙈

---

🌈 RETURN 🌈

the return value is the nvme command status if a response was received — peep enum nvme_status_field for what those numbers mean, iykyk 👑

or, if things went sideways: -1 with errno set. so yeah, check errno, she'll tell you what happened 💜

---

🦋 SEE ALSO 🦋

hmm, the original didn't actually give us a SEE ALSO section here 😭 (i know, i know). but the description points you at nvme_get_features_err_recovery2, so that's your girl ✨
