💖 libnvme(9) — API Manual 💖

okay bestie, pull up a chair, we're doing a whole struct today. this is from the libnvme(9) API Manual, and it's giving "i need to know where my LBAs stand" energy. no cap, it's a good one. 🦋

---

✨ NAME ✨

struct nvme_get_lba_status_args — literally just the arguments bag for the NVMe Get LBA Status command. that's it, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

struct nvme_get_lba_status_args {
    __u64 slba;
    __u32 *result;
    struct nvme_lba_status *lbas;
    int args_size;
    int fd;
    __u32 timeout;
    __u32 nsid;
    __u32 mndw;
    enum nvme_lba_status_atype atype;
    __u16 rl;
 };

look at her. ten fields. absolutely iconic. 👑

okay so every single one of these fields, one by one, no skipping, we respect the lore:

• slba — the starting logical block address you wanna check statuses on. this is where the little investigation begins, bestie 🔍
• result — the command completion result, straight from CQE dword0. the receipts, fr fr 💅
• lbas — the data payload that's gonna come back holding your status descriptors. it's giving "the answer sheet" 📋
• args_size — the size of struct nvme_get_lba_status_args. yes it knows its own size, self-aware queen ✨
• fd — file descriptor of the nvme device. your lil portal to the drive 🌀
• timeout — timeout in ms. don't wait forever, we have places to be ⏰
• nsid — namespace ID to retrieve LBA status from. gotta specify which namespace, we don't do ambiguity here 🎯
• mndw — maximum number of dwords to return. set your limit, know your limit 🚦
• atype — the action type mechanism that decides which LBA status descriptors get returned, see enum nvme_lba_status_atype. the choose-your-own-adventure field 🌈
• rl — range length from slba to perform the action over. how far down the block road are we going 🛣️

heads up bestie: that atype one points you at enum nvme_lba_status_atype — go read it before you just toss a random value in there, iykyk 👀

and that's the whole page!! every field, every type, every detail, preserved with love and zero skips. periodt. 💜

this cutie came to you from the libnvme source, and the version we're repping is dated August 2026 — yeah, from the future, she's that ahead. mwah, bye bestie!! 💖✨🎀🦋🌸💅
