rsi_set_antenna(9)

🦋 rsi_set_antenna(9) — a Kernel API Manual moment 🦋

okay so bestie, listen. this one lives in the Kernel API Manual, section 9, and it's genuinely such a neat little function. no cap.

---

✨ NAME ✨

rsi_set_antenna — this function sends the antenna configuration request to the device. that's it. that's the whole job. she's focused, she's got main character energy, she ships the antenna config and she leaves 💅

---

🌸 SYNOPSIS 🌸

int rsi_set_antenna (struct rsi_common *common , u8 antenna );

literally right there. two arguments, returns an int. iconic.

---

🎀 ARGUMENTS 🎀

• common — pointer to the driver private structure. yes queen, hand over your driver's whole inner world, she needs it 🫶
• antenna — the bitmap for tx antenna selection. it's giving "which antennas are we transmitting on" and honestly? obsessed 🌈

---

⭐ RETURN ⭐

• 0 on Success 🔥
• a negative error code on failure 😭

so like, vibe check the return value, bestie. 0 means slay, anything negative means something went sideways.
