rc_keydown(9)

✨ rc_keydown(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for rc_keydown(9) — yes the whole page is about this one tiny function and honestly? it's giving main character energy 💅

---

🌸 NAME 🌸

rc_keydown — literally generates an input event for a key press. that's it. that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

void rc_keydown (struct rc_dev *dev , enum rc_proto protocol , u64
scancode , u8 toggle );

no cap, that's the whole signature. stay with me, we're gonna walk through every single parameter 🫶

---

💖 ARGUMENTS 💖

• dev — the struct rc_dev descriptor of the device 👑 like, the whole remote control's identity card, y'know?
• protocol — the protocol for the keypress 📡 which dialect your remote is speaking, basically.
• scancode — the scancode for the keypress 🔢 the raw little number the button sent out into the world.
• toggle — the toggle value — and here's the tea, it's protocol dependent 🙈 if the protocol doesn't support toggle values, this should be set to zero. zero. not one. not "whatever". zero ⭐

---

✨ DESCRIPTION ✨

so this routine is used to signal that a key has been pressed on the remote control 💀 that's the entire description, she's short and she knows it. iconic. use it when a button goes down, periodt.
