nvme_get_log_ana(2)

✨ nvme_get_log_ana ✨

okay bestie, so this is a page from the libnvme API manual 💖 and it's all about one little function called nvme_get_log_ana — she retrieves the Asymmetric Namespace Access log page. Yeah. That's the whole assignment. Let's get into it 🦋

---

🌸 NAME 🌸

nvme_get_log_ana — Retrieve Asymmetric Namespace Access log page 💅

---

✨ SYNOPSIS ✨

int nvme_get_log_ana (int fd , enum nvme_log_ana_lsp lsp , bool rae ,
__u64 offset , __u32 len , void *log );

like. six arguments. she's got range, ok 💀

---

🎀 ARGUMENTS 🎀

• fd — the file descriptor of the nvme device. that's your ticket in, no ticket no log 🎟️
• lsp — log specific, see enum nvme_get_log_ana_lsp. the ✨flavor✨ selector, iykyk
• rae — retain asynchronous events. a bool, so it's giving true/false main character energy
• offset — offset to the start of the log page. like where you start reading in the group chat 📜
• len — the allocated length of the log page. how much room you gave her
• log — user address to store the ana log. this is where the tea gets poured 🫖

---

💜 DESCRIPTION 💜

so this log literally consists of a header describing the log, plus descriptors that contain the asymmetric namespace access information for ANA Groups that contain namespaces attached to the controller processing the command. that's the vibe. that's what you're getting back.

if you wanna see the definition of the returned structure, go look at struct nvme_ana_log — she's right there, go say hi 🫶

---

🌈 RETURN 🌈

so what comes back? either the nvme command status if a response was received — check enum nvme_status_field for that — or -1 with errno set otherwise. so like. -1 means it did NOT slay. set your errno-checking habits accordingly 😭

ngl bestie, always check the return value before you start celebrating. -1 is not the moment for confetti 🎊

and that's the page!! she was written in July 2026 for the libnvme API manual, which means the source is libnvme and the date on her birth certificate is that month. iconic. periodt. go log some asymmetric namespace access information, queen 👑💖
