✨ ieee80211_operating_class_to_band(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9 (yes, the 9 — that's the kernel-functions section, iykyk 🫶). today's main character is ieee80211_operating_class_to_band, and honestly? she's a little translator icon and we're obsessed 💅

💖 NAME 💖

ieee80211_operating_class_to_band — convert operating class to band

like, she takes an operating class and turns it into a band. that's the whole vibe. slay.

🦋 SYNOPSIS 🦋

bool ieee80211_operating_class_to_band(u8 operating_class, enum nl80211_band *band);

literally just one function call, no drama, no cap:

bool ieee80211_operating_class_to_band (u8 operating_class , enum nl80211_band *band );

🌸 ARGUMENTS 🌸

  • operating_class — the operating class to convert 🎀 this is the <italic>u8</italic> you're handing over, and she's gonna do her thing with it.
  • band — band pointer to fill ✨ note the "to fill" bestie, because this one is an out-param: it's a pointer to an enum nl80211_band and the function fills it in for you. it's giving "you bring the container, i bring the content" 🫶

👑 RETURN 👑

  • true — the conversion was successful 🌈 periodt, you got your band.
  • false — otherwise 😭 the conversion did not go through.
ngl this one is short and sweet, but don't get too comfy — there's more coming in the next parts, so stay tuned bestie 💜

✨ SEE ALSO ✨

okay bestie, this is the part where the page hands you the whole friend group 😭 — every single cross-reference, no gatekeeping, and there are literally hundreds of them. Grab a snack 🍓, we're going through them all. Not one dropped, not one merged, fr fr.
