✨ ieee80211_is_rts — check if IEEE80211_FTYPE_CTL && IEEE80211_STYPE_RTS ✨

okay so bestie, welcome to the ieee80211_is_rts(9) page from the Kernel API Manual 💅 this one is short and sweet and honestly kind of iconic — it's the little helper that looks at your frame control bytes and goes "hmm… is this an RTS frame or not?" 🎀

🌸 NAME 🌸

ieee80211_is_rts — check if IEEE80211_FTYPE_CTL && IEEE80211_STYPE_RTS 🦋

💖 SYNOPSIS 💖

bool ieee80211_is_rts (__le16 fc );

🧚 ARGUMENTS 🧚

• fc — the frame control bytes, in little-endian byteorder ⭐ like, that's the whole vibe check right there, no cap.

👑 RETURN 👑

returns whether or not the frame is an RTS frame 💀 so like, true if it is, and not-if-it-isn't. slay.

ngl this one is a pure predicate — it doesn't mutate anything, it just tells you what's up 🫶
