mesh_path_lookup_by_idx(9)

💫 mesh_path_lookup_by_idx(9) 💫

okay so bestie, welcome to the Kernel API Manual entry for mesh_path_lookup_by_idx — yes it's a mouthful, yes it's iconic, and yes we're gonna get through it together 🫶

✨ NAME ✨

mesh_path_lookup_by_idx — it looks up a path in the mesh path table by its index. that's the whole vibe. index in, path out 🎀

🌸 SYNOPSIS 🌸

struct mesh_path * mesh_path_lookup_by_idx (struct ieee80211_sub_if_data
*sdata , int idx );

it's giving "one function, two arguments, zero drama" ✨

🦋 ARGUMENTS 🦋

• sdata — the local subif bestie 💅 or, plot twist, NULL if you want all entries. yeah. NULL means everybody gets an invite to the party 🎉
• idx — the index. that's it. that's the argument. it's literally just the index 😭

🔥 RETURN 🔥

a pointer to the mesh_path structure 💖 — or NULL if it wasn't found 🙈 (no path for you, babes).

👑 DESCRIPTION 👑

Locking: you must call this within a read rcu section. not "should", not "maybe", must ⚠️ so like… do that first, okay? i'm not gonna say it twice (i will say it twice).
