💖 libnvme(9) — API Manual 💖

okay bestie, welcome to the libnvme API manual, section 9 🎀 this one's a lil struct deep-dive and honestly it's giving "I have a very specific job and I do it flawlessly" energy ✨

---

✨ NAME ✨

struct nvme_zns_mgmt_recv_args — the arguments for the NVMe ZNS Management Receive command 🦋

no cap, that's literally the whole vibe. it's the lil bag of stuff you hand over when you wanna do a ZNS management receive.

---

🌸 SYNOPSIS 🌸

struct nvme_zns_mgmt_recv_args {
    __u64 slba;
    __u32 *result;
    void *data;
    int args_size;
    int fd;
    __u32 timeout;
    __u32 nsid;
    enum nvme_zns_recv_action zra;
    __u32 data_len;
    __u16 zrasf;
    bool zras_feat;
 };

look at her. eleven members. all accounted for. iconic. 👑

💅 Members 💅

one bullet per member, and yes we're doing all of them, because skipping members is not the move 🙈

• slba — the Starting logical block address. where the party starts 📍
• result — the command completion result, straight outta CQE dword0 🎯
• data — the userspace address of the data. yes bestie, your buffer lives here 🏠
• args_size — the size of struct nvme_zns_mgmt_recv_args. she knows her own measurements, self-aware queen 💖
• fd — the file descriptor of the nvme device 🔌
• timeout — timeout in ms ⏳ (milliseconds, fr fr)
• nsid — Namespace ID 🪪
• zra — zone receive action 🌀
• data_len — length of data 📏
• zrasf — Zone receive action specific field 🔍
• zras_feat — Zone receive action specific features ✨

ngl bestie, if you're passing this struct around, double-check args_size matches what you think it is — she's the one telling everyone how big the struct is, and she does not want to be wrong about it 😭

and that's the whole page, we ate and left no crumbs 🍓
