💖 libnvme(9) — API Manual 💖

okay bestie, welcome to the libnvme zone, where we talk about the C API like it's the group chat and every struct is a little main character. this one? it's about struct nvme_zns_mgmt_send_args, aka the argument bundle for the NVMe ZNS Management Send command. no cap, it's giving "one struct to hold all your send-command vibes." ✨

🌸 NAME 🌸

struct nvme_zns_mgmt_send_args — the arguments for the NVMe ZNS Management Send command 🦋

✨ SYNOPSIS ✨

here's the whole glow-up, verbatim, don't touch a single semicolon bestie:

struct nvme_zns_mgmt_send_args {
    __u64 slba;
    __u32 *result;
    void *data;
    int args_size;
    int fd;
    __u32 timeout;
    __u32 nsid;
    enum nvme_zns_send_action zsa;
    __u32 data_len;

okay so let's go field by field, like we're doing a little tour of the struct. every single one, no skipping, periodt. 💅

• slba — starting logical block address. this is where the party begins 📍
• result — the command completion result, straight from CQE dword0 👑
• data — the userspace address of the data. that's your buffer's home address fr fr 🏠
• args_size — the size of struct nvme_zns_mgmt_send_args. yes she knows her own size, iconic 🌈
• fd — file descriptor of the nvme device 🔌
• timeout — timeout in ms ⏳
• nsid — namespace ID 🏷️
• zsa — zone send action 🌸
• data_len — length of the data 📏
• select_all — the select all flag ✨
• zsaso — Zone Send Action Specific Option 🎀

lowkey reminder bestie: these fields get copied and referenced exactly as written. don't be out here renaming things or "fixing" types, that's not the vibe. 🙈
