💖 ipc_mux_open_session(9) 💖

okay bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 🫶 and today's main character is a little function called ipc_mux_open_session.

✨ NAME ✨

ipc_mux_open_session — literally just opens a MUX session for IP traffic. that's it, that's the whole vibe 💅

✨ SYNOPSIS ✨

int ipc_mux_open_session (struct iosm_mux *ipc_mux , int session_nr );

look at her. two args. very demure, very mindful 🌸

✨ ARGUMENTS ✨

• ipc_mux — a pointer to the MUX data-struct 🎀 (yes the actual struct, not a copy, we're not playing games here)
• session_nr — the Interface ID or the session number, whichever name you're feeling today 🦋

✨ RETURN ✨

on success you get the channel id back — slay 👑 — and on error you get a failure value 😭 so like, always check her return value fr fr.

✨ SEE ALSO ✨

okay this is the friend group and they ALL need their shoutouts, no one gets left out 💜
