🌈 struct rtrs_msg_conn_rsp(9) 🌈

💖 NAME 💖

struct rtrs_msg_conn_rsp — the server connection response to the client, bestie. This one's from the Kernel API Manual, and it's giving “server replies in the group chat” energy. 💅

🦋 SYNOPSIS 🦋

okay so the struct is literally this, no edits:

struct rtrs_msg_conn_rsp {
    __le16 magic;
    __le16 version;
    __le16 errno;
    __le16 queue_depth;
    __le32 max_io_size;
    __le32 max_hdr_size;
    __le32 flags;
};

🎀 Members 🎀

• magic — RTRS magic ✨
• version — RTRS protocol version 🦋
• errno — if rdma_accept then 0; if rdma_reject it indicates error 💀
