💅 ieee80211_is_cts — check if IEEE80211_FTYPE_CTL && IEEE80211_STYPE_CTS

okay so bestie, welcome to the Kernel API Manual entry for ieee80211_is_cts, and honestly? it's a little icon. it does one tiny thing and it does it flawlessly. no notes.

---

✨ NAME ✨

ieee80211_is_cts — check if IEEE80211_FTYPE_CTL && IEEE80211_STYPE_CTS

like, that's the whole job description. it checks whether your frame control situation is giving type = control AND subtype = CTS. slay.

---

🌸 SYNOPSIS 🌸

bool ieee80211_is_cts (__le16 fc );

copy it exactly bestie, don't freestyle the signature 💀

---

🎀 ARGUMENTS 🎀

• fc — the frame control bytes, in little-endian byteorder. that's it. that's the whole input. she's low maintenance.

---

🦋 RETURN 🦋

returns whether or not the frame is a CTS frame 💖 — so like, true if yes, and if it's not a CTS frame, well… not true. the vibe check happens, the answer comes back.

ngl there are no warnings, no bugs, no exit statuses on this one — it's a pure little "is it or is it not" check and it understood the assignment.

mwah 💋 that's the whole page! quick cute sign-off: this lil masterpiece lives in the kernel file at ./include/linux, it's stamped October 2026, and it goes by ieee80211_is_cts(9) — periodt. ✨🍓
