nvme_get_log_error(2)

💖 nvme_get_log_error — bestie's guide to the error log 💖

okay so this is nvme_get_log_error from the libnvme API manual, section 2, and honestly? she's a whole vibe. she goes and grabs the NVMe error log for you. that's it. that's the girl. ✨

---

✨ SYNOPSIS ✨

int nvme_get_log_error (int fd , unsigned int nr_entries , bool rae ,
       struct nvme_error_log_page *err_log );

like yes she takes four things and gives you back an int, no cap. 🫶

---

🎀 ARGUMENTS 🎀

• fd — the file descriptor of your nvme device. your lil handle to the hardware. the passport. the ✨access✨.
• nr_entries — how many error log entries you allocated. as in, how much room you set aside. you gotta actually make room, bestie, she's not gonna conjure it out of thin air. 💅
• rae — retain asynchronous events. a bool. yes or no, iconic or not. 🌸
• err_log — an array of error logs, sized 'entries'. this is where all the tea gets poured. 🍓

---

🌈 DESCRIPTION 🌈

so listen. this log page spills the extended error info for a command that completed with an error — like, the receipts on what went wrong. and sometimes? sometimes it's also reporting an error that isn't even tied to one specific command. just a general "something's off" moment. main character error energy, honestly. 💀

---

⭐ RETURN ⭐

you get back the nvme command status if a response actually came through — check enum nvme_status_field for what that status means, iykyk.

but if things went sideways? you get -1, and errno is set. that's the "not me getting an error while getting the errors" situation. 😭

---

🌸 SEE ALSO 🌸

okay so there's no SEE ALSO section in this one — go look at enum nvme_status_field if you wanna decode your status, that's the one she points at. 💜

---

and that's the whole page, bestie, you ate. mwah. 💅✨
