💅 NAME 💅

okay so bestie, this is ovpn_nl_key_swap_notify(9) from the Kernel API Manual — say hi 👋 — and it's literally the function that notifies userspace that a peer's key must be renewed. that's the whole vibe. it's giving "hey bestie, time for a new key" 🎀

✨ SYNOPSIS ✨

int ovpn_nl_key_swap_notify (struct ovpn_peer *peer , u8 key_id );

no cap, that's the whole signature. int going in, int coming out, two args in the middle. slay 💅

🫶 ARGUMENTS 🫶

  • peer — the peer whose key needs to be renewed 🧚 like, the actual main character here. this is the one whose key is getting the glow-up.
  • key_id — the ID of the key that needs to be renewed 🔑✨ it's a u8, so keep it cute and keep it small.

🌈 RETURN 🌈

  • 0 on success 🎉 (we love a zero, zero is the happy number)
  • a negative error code otherwise 😭 (not slaying, but that's how it is)
