🦋 ieee80211_generic_frame_duration — the duration-field girlie 💅

okay so first things first, hi bestie, welcome to the Kernel API Manual ✨ this is the page for ieee80211_generic_frame_duration(9) and honestly? it's a little cutie. it does exactly one thing and it does it slayfully: it tells you how long a frame is gonna take on the air. that's it. that's the whole vibe. 🎀

🌸 NAME 🌸

ieee80211_generic_frame_duration — Calculate the duration field for a frame ⏱️✨

🧚 SYNOPSIS 🧚

__le16 ieee80211_generic_frame_duration (struct ieee80211_hw *hw ,
struct ieee80211_vif *vif , enum nl80211_band band , size_t frame_len ,
struct ieee80211_rate *rate );

💖 ARGUMENTS 💖

  • hw — a pointer you got from ieee80211_alloc_hw. like, the hardware's whole identity, no cap.
  • vif — a struct ieee80211_vif pointer that comes from the add_interface callback. it's giving "this is the interface we're doing the thing on" energy 🫶
  • band — the band you want to calculate the frame duration on. yes queen, tell it which band. 🌈
  • frame_len — the length of the frame. how big is she? 📏
  • rate — the rate at which the frame is going to be transmitted. the speed, the pace, the main character energy of the transmission 🔥

✨ DESCRIPTION ✨

so what does it actually do? it calculates the duration field of some generic frame, given its length and transmission rate (in 100kbps). that's literally the whole function. length + rate in, duration out. iconic, lowkey, extremely efficient 💅

👑 RETURN 👑

The duration. that's it. that's the return value. she gives you the duration and she goes home 💜

🔥 SEE ALSO 🔥

bestie. sit down. this list is long long. like, "she has a lot of friends" long. but every single one of them matters, so here we go, no skipping, fr fr 🌸
