rsi_channel_change(9)

💅 rsi_channel_change — a kernel API manual page (section 9, bestie)

okay so picture this: you're deep in the kernel API manual, section 9, and you stumble on rsi_channel_change(9). That's her. That's the main character. 💖

✨ NAME ✨

rsi_channel_change — this function performs the checks required for changing a channel and then sets the channel accordingly. (The original page says "is a performs," which is a little typo moment, but we move — the meaning is fully giving "validate first, then commit." 🎀)

🌸 SYNOPSIS 🌸

int rsi_channel_change (struct ieee80211_hw *hw );

🦋 ARGUMENTS 🦋

• hw — a pointer to the ieee80211_hw structure. That's it. That's the whole ask. 🫶

⭐ RETURN ⭐

• 0 on success — slay, we're so back ✨
• a negative error code on failure — not slay, but honestly iconic of it to tell you 😭

heads up bestie: this page only promises what's written above — the checks happen, then the channel gets set, and you get 0 or a negative error code. Don't go inventing behaviour, that's not the vibe check we're passing today 🙈
