UNION MUX_CMD_PARAM(9)

✨ NAME ✨

okay so bestie, welcome to mux_cmd_param(9) — this is the man page for union mux_cmd_param, which is literally the union-definition of the command parameters. that's the whole vibe. it's a union that holds all the inband command payloads so everybody can share one spot 💅

🌸 SYNOPSIS 🌸

union mux_cmd_param {
    struct mux_cmd_open_session open_session;
    struct mux_cmd_open_session_resp open_session_resp;
    struct mux_cmd_close_session_resp close_session_resp;
    struct mux_cmd_flow_ctl flow_ctl;
    struct mux_cmd_link_status_report link_status;
    struct mux_cmd_link_status_report_resp link_status_resp;
 };

like, that's it. that's the union. six members sharing one little home 🏠 no cap.

🎀 Members 🎀

bestie, meet the cast. each one is a different flavor of command parameter, and they all live in the same union:

• open_session — the inband command for open session. it's giving "let's start something" energy ✨
• open_session_resp — the inband command for open session response. the reply era 🫶
• close_session_resp — the inband command for close session response. wrapping it up, saying bye 😭
• flow_ctl — in-band flow control on the opened interfaces. keeping the traffic from getting messy, lowkey iconic 🌊
• link_status — in-band Link Status Report. the vibe check of the link, fr fr 📡
• link_status_resp — in-band command for link status report response. the link status report's response bestie 🦋
