ieee80211_mle_common_size(9)

💅 ieee80211_mle_common_size(9) — the kernel API manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual (yes, the (9) section, we're in deep kernel territory, main character energy fr) and it's all about ieee80211_mle_common_size. she's a tiny little function but she's important, so let's get into it ✨

---

🌸 NAME 🌸

ieee80211_mle_common_size — checks the common size of the multi-link element 👑

like, that's literally the whole job. she checks the multi-link element's common size. no cap. 💅

---

🦋 SYNOPSIS 🦋

u8 ieee80211_mle_common_size (const u8 *data );

she takes one thing, she gives you back a u8. simple. iconic. don't overthink her 🫶

---

🎀 ARGUMENTS 🎀

• data — the multi-link element itself 💖 but bestie, listen to me: it must already be checked for size using ieee80211_mle_size_ok first. like, that's not optional, that's the vibe check before the vibe check. do it before you call this. periodt 🙈

fr fr, don't skip the ieee80211_mle_size_ok step. the manpage says "must", and "must" means must, bestie 😭

---

⭐ RETURN ⭐

she returns the size of the multi-link element's "common" subfield 💫 that's it, that's the whole gift. a u8, sized at the return statement, slay 🌈
