ieee80211_has_morefrags(9)

💅 ieee80211_has_morefrags — kernel API manual, section 9 🎀

okay so bestie, welcome to ieee80211_has_morefrags(9) from the Kernel API Manual. this is a tiny little helper that lives in the wireless headers and it does exactly one (1) thing, and honestly? it does it flawlessly. main character energy: minimal, focused, no notes. 🦋

---

✨ NAME ✨

ieee80211_has_morefrags — check if IEEE80211_FCTL_MOREFRAGS is set

like… that's the whole job. it checks if the bit is set. that's it. and we stan a function that knows its purpose. 👑

---

🌸 SYNOPSIS 🌸

bool ieee80211_has_morefrags (__le16 fc );

literally just hand it the frame control bytes and it hands you back a bool. no drama, no side quests, no allocation. 🫶

---

🎀 ARGUMENTS 🎀

• fc — the frame control bytes, in little-endian byteorder. yes, little-endian, bestie, keep that in mind, the byteorder is not a vibe you can just ignore. 🙈

---

⭐ RETURN ⭐

it returns whether or not the frame has more fragments — i.e. whether the more frags bit is set. true = more frags, false = no more frags. that's the vibe check. ✨

ngl this page is short but it ate. one argument, one return value, zero confusion. periodt. 💅

okay that's the page!! this came from ./include/linux and it's tagged October 2026 — so like, mark your calendars bestie, and go check that more frags bit. mwah! 🍓🧚💜
