mpp_path_lookup_by_idx(9)

💅 mpp_path_lookup_by_idx 💅

okay so this is a page from the Kernel API Manual (mpp_path_lookup_by_idx(9)), and honestly? it's short, it's sweet, and it does exactly what it says on the tin. let's get into it bestie 🫶

---

✨ NAME ✨

mpp_path_lookup_by_idx — look up a path in the proxy path table by its index 🔍

like, you give it an index, it goes digging in the proxy path table, and it comes back with a path. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

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

that's the whole call, bestie — two args, one return, no drama. ✨

---

🎀 ARGUMENTS 🎀

• sdata — the local subif. you can also pass NULL to mean all entries 👀 (yes, literally all of them, it's giving main character energy)
• idx — the index. that's it. that's the arg. 💅

---

💖 RETURN 💖

a pointer to the proxy path structure 🎯 … or NULL if it wasn't found 😭 (ngl, that's the sad path)

---

🦋 DESCRIPTION 🦋

Locking: this one has to be called within a read rcu section. no cap. that's not a suggestion, that's the rule 🔒✨

fr fr, respect the locking. it's giving "read it and weep if you don't."
