ieee80211_mle_get_eml_cap(9)

💅 ieee80211_mle_get_eml_cap(9) — the Kernel API Manual page, bestie edition

okay so this one's from the Kernel API Manual and it's literally so straightforward, we're just grabbing one little field out of a multi-link element and running away with it. no cap, it's giving "one-line helper, main character energy." 🎀

---

✨ NAME ✨

ieee80211_mle_get_eml_cap — returns the EML capability 🦋

✨ SYNOPSIS ✨

u16 ieee80211_mle_get_eml_cap (const u8 *data );

✨ ARGUMENTS ✨

• data — pointer to the multi-link element. that's it. that's the whole argument. she's just a const u8 * pointing at your multi-link element and honestly she's slaying 💅

✨ RETURN ✨

it hands you back the EML capability field value from the multi-link element. and if it's not present? you get 0, bestie. empty hands, zero drama 🙈

✨ DESCRIPTION ✨

so here's the vibe check: the element is assumed to be of the correct type — that's BASIC — and big enough. but "assumed" is doing so much heavy lifting here, because this function does not check any of that for you 😭

⚠️ literally must be checked using ieee80211_mle_type_ok. do not skip this step. this is not a drill. she trusts you, and you should not betray her 💀
