💫 rio_enum_peer(9) 💫

okay so this is a page from the Kernel API Manual, bestie, and it's literally all about rio_enum_peer — the function that recursively enumerates a RIO network through a master port. yes queen, we're going networking today 🦋

---

✨ NAME ✨

rio_enum_peer — recursively enumerate a RIO network through a master port. that's the whole vibe. no cap. 💅

---

🌸 SYNOPSIS 🌸

int rio_enum_peer (struct rio_net *net , struct rio_mport *port , u8
hopcount , struct rio_dev *prev , int prev_port );

look at her. five arguments. she's iconic, she's built different, she returns an int. periodt. 👑

---

🎀 ARGUMENTS 🎀

• net — the RIO network being enumerated. like, the whole friend group we're walking through 💖
• port — the master port that sends the transactions. she's the one doing the talking, fr fr 📣
• hopcount — number of hops into the network. the deeper we go, the bigger this gets 🧚
• prev — the previous RIO device connected to the one being enumerated. the one who came before, holding hands with the new one 🫶
• prev_port — the port on that previous RIO device. yeah. that specific port. 🎯

---

💜 DESCRIPTION 💜

so basically: this function recursively enumerates a RIO network. the transactions get sent via the master port you passed in as port — that's it, that's the whole story. she recurses, she enumerates, she slays. and honestly? the way that she just keeps going deeper into the network? main character energy, lowkey. 🔥
