batadv_gw_dump(9)

💅 batadv_gw_dump — NAME

okay so, bestie, this is batadv_gw_dump(9) from the Kernel API Manual (section 9, the kernel-functions girlies ✨) — and what it does is literally dump gateways into a message. that's it, that's the whole vibe 🎀

✨ SYNOPSIS ✨

int batadv_gw_dump (struct sk_buff *msg , struct netlink_callback *cb );

int function, two args, no notes. slay 🫶

🌸 ARGUMENTS 🌸

• msg — the netlink message we're dumping into. it's the canvas, the receptacle, the main character of the operation 💖 typed as struct sk_buff *, obviously.
• cb — the control block that's carrying all the extra options around. struct netlink_callback *. it's giving "guy with the clipboard" energy 📋✨

🔥 RETURN 🔥

it hands back an error code, or the length of the message — which one you get depends on whether it worked, and ngl that's the whole plot 😭
