netlbl_af4list_add(9)

💖 netlbl_af4list_add(9) — like, the Kernel API Manual bestie 🎀

okay so real talk, this one's from the Kernel API Manual and it's a tiny little function that does exactly one thing and does it slay ✨

---

🌸 NAME 🌸

netlbl_af4list_add — add a new IPv4 address entry to a list 🦋

---

✨ SYNOPSIS ✨

int netlbl_af4list_add (struct netlbl_af4list *entry , struct list_head
*head );

---

🎀 ARGUMENTS 🎀

• entry — the address entry, like, the actual thing you're adding 💅
• head — the list head (the main character of the list, fr fr) 👑

---

🫶 DESCRIPTION 🫶

So what it does is: it adds a new address entry to the list that head is pointing at. That's it. That's the whole vibe 🦋

On success you get zero back. Anything else and it's a negative value — not zero, so, not a slay 😭

⚠️ Heads up bestie: the caller is responsible for calling the necessary locking functions. That's on you, not on this function. No cap, don't forget it 💀
