cfg80211_any...ble_channels(9)

📦 version 7.3.1, in nixpkgs unstable
🌸 bestie welcome to part 1 of 3 of the cfg80211_any...ble_channels page — that truncated title is the man page being dramatic, it's really cfg80211_any_usable_channels — straight out of the Kernel API Manual, section 9. grab a snack, we're just getting started 💖

✨ NAME ✨

cfg80211_any_usable_channels — check for usable channels 🎀

✨ SYNOPSIS ✨

bool cfg80211_any_usable_channels (struct wiphy *wiphy , unsigned long
band_mask , u32 prohibited_flags );

🦋 ARGUMENTS 🦋

  • wiphy — the wiphy we're checking, like, the actual thing you want the vibe check on 🔍
  • band_mask — which bands to check on, so you pick the bands, no cap 🌈
  • prohibited_flags — which channels to not consider usable. and heads up bestie, IEEE80211_CHAN_DISABLED is always taken into account, every single time, it's not optional 💀

⭐ RETURN ⭐

true if usable channels found, false otherwise — that's it, that's the whole answer, short and iconic 👑

still with me? good, because the next parts are coming and there's more to cover 🫶

✨ SEE ALSO ✨

okay bestie, this is the part where the page just lists everyone. it's giving end-of-movie credits, except every single name is a struct or a function from the cfg80211 cinematic universe 🌈. i'm keeping every single one, no skipping, no cap — because missing one of these is how you end up lost at 2am 🫶.

and that's the capability squad ✨. now we get into the configuration era, which lowkey is the main character of this whole page 💅:

station info? station iconic 👑. anyway, next up is the scanning chapter and honestly it ate:
