netlbl_af4list_search(9)

💅 NAME 💅

okay so bestie, welcome to netlbl_af4list_search(9) — yes, that's the title, and yes, it's from the Kernel API Manual (section 9, iykyk). This one is all about searching for a matching IPv4 address entry ✨🔎

✨ SYNOPSIS ✨

struct netlbl_af4list * netlbl_af4list_search (__be32 addr , struct
list_head *head );

🎀 ARGUMENTS 🎀

• addr — the IPv4 address, literally the address you're hunting for 🕵️‍♀️
• head — the list head, aka where the list starts, the main character of this linked-list moment 👑

🦋 DESCRIPTION 🦋

So it searches the IPv4 address list given by head. If a matching address entry is found, it gets returned — slay 💅. Otherwise, you get NULL, and that's just how it is 😭.

heads up, bestie: the caller is responsible for calling the rcu_read_[un]lock functions. no cap, that part is on you 🫶
