nvme_get_fe...rr_recovery2(2)

💖 nvme_get_features_err_recovery2 💖

okay bestie, this one lives in the libnvme API manual (it's section 2 of the manual pages, iykyk) and it's literally just one little function called nvme_get_features_err_recovery2 — it goes and gets the error recovery feature. that's the whole vibe. 🦋

✨ NAME ✨

nvme_get_features_err_recovery2 — get the error recovery feature 💅

---

🌸 SYNOPSIS 🌸

int nvme_get_features_err_recovery2 (int fd , enum nvme_get_features_sel
sel , __u32 nsid , __u32 *result );

like… she takes four things and gives you back an int. no cap. 🎀

🫶 ARGUMENTS 🫶

• fd — the file descriptor of your nvme device, bestie. it's your little handle to the drive, okurrr.
• sel — which flavor of attribute you want back. this is not a mystery, you pick from enum nvme_get_features_sel. choose wisely 👑
• nsid — the Namespace ID. which namespace are we talking about? this one.
• result — pointer where the good stuff lands: the command completion result from CQE dword0. that's the drive's little receipt for what happened ✨

---

💀 RETURN 💀

so here's the tea:

• if a response came back, you get the nvme command status (peep enum nvme_status_field for what those mean).
• otherwise you get -1 and errno is set. 😭 yeah. it's giving "something went wrong and you gotta go read errno yourself."

and that's the whole page, fr fr. no hidden options, no extra flags, just vibes and one syscall-adjacent bestie doing her job. 💖
