rsi_set_channel(9)

🌸 rsi_set_channel — NAME 💅

okay so rsi_set_channel — literally the function that programs the channel. that's it, that's the whole vibe. ✨

---

🎀 SYNOPSIS

int rsi_set_channel (struct rsi_common *common , struct
       ieee80211_channel *channel );

it takes two things and hands you back an int, bestie. we love a simple signature. 🫶

---

🦋 ARGUMENTS

• common — pointer to the driver private structure. like, the driver's whole personality lives in there.
• channel — the channel value you want set. the actual channel. the one being programmed. girl, that's the whole assignment. 🎯

---

⭐ RETURN

0 on success 🎉 — literally the yes.

on failure you get the corresponding error code instead 😭 so like, check it, don't just vibe and assume.

no cap, 0 is the slay outcome. anything else is the "we need to talk" outcome. 💀
