mptcp_token_iter_next(9)

💅 mptcp_token_iter_next — kernel API manual, but make it make sense

okay so bestie, this one's a kernel function from the MPTCP token container, and the vibe is: you're walking through a container of tokens, one socket at a time, and this function hands you the next one. it's giving tour guide energy 🧚

---

✨ NAME ✨

mptcp_token_iter_next — iterate over the token container from given pos 🎀

---

🌸 SYNOPSIS 🌸

struct mptcp_sock * mptcp_token_iter_next (const struct net *net , long
*s_slot , long *s_num );

like literally that's the whole signature, no cap 💅

---

🦋 ARGUMENTS 🦋

• net — the namespace you're iterating over. that's the world you're walking through, bestie 🌍
• s_slot — the start slot number. where you're starting your little stroll 👑
• s_num — the start number inside the given lock. yes, that's what it says, i'm just relaying the message 🫶

---

💖 DESCRIPTION 💖

so on a successful iteration, two things happen, and you need to know both:

• the iterator gets moved to the next position ➡️
• a reference to the returned socket is acquired 🔥

that reference part is the main character energy here — don't sleep on it 😭

---

⭐ RETURN ⭐

the first mptcp connection structure found inside the token container, starting from the specified position. and if there's nothing there? NULL. that's it, that's the whole answer 💀

ngl this one's short but she's got range — iterate responsibly and remember that reference gets acquired, so act accordingly 🙈
