cfg80211_wext_freq(9)

💖 cfg80211_wext_freq — like, the whole vibe 💖

okay so bestie, this one's a lil kernel function from the Kernel API Manual (yes that's the manual name, we're fancy now ✨), and honestly? she's short but she delivers. Let's get into it 🎀

🌸 NAME 🌸

cfg80211_wext_freq — get wext frequency for non-"auto" 🦋

Like, the whole point: you hand her a wext frequency thingy and she tells you the actual frequency. But — and this is the iconique part — only for the non-"auto" case. If it's "auto", girl has a whole other answer for you (spoiler: it's 0, scroll down 💅).

---

✨ SYNOPSIS ✨

int cfg80211_wext_freq (struct iw_freq *freq );

That's it. One function, one argument, no cap. Copy it exactly, spaces and all, because kernel code does not do ~vibes~ with your formatting 🙈

---

🫶 ARGUMENTS 🫶

• freq — the wext freq encoding. That's the input, bestie. It's a struct iw_freq *, and it's carrying the encoded frequency info. She reads it, she decodes the situation, she reports back. Main character energy honestly 👑

---

🔥 RETURN 🔥

So what comes back? One of three moods, depending on the day:

• a frequency — the happy path, she found you a real number 🌈
• a negative error code — something went sideways, and the negative value is her telling you how sideways 💀
• 0 — for auto. That's the "auto" case from NAME, coming back around to say hi ⭐

Heads up: 0 is a real, meaningful return here — it means "auto", not "everything's fine, here's a zero frequency." Don't get it twisted 😭

👑 SEE ALSO 👑

Kernel file ./net/wireless/wext-compat.c — that's where she lives, go say hi 🧚

and that's the page, bestie 🍓 fr fr you read the whole thing, proud of you 💜 this was the Kernel API Manual, from ./net/wireless, dated October 2026 — mwah, slay, periodt 💅✨
