ir_rc6_decode(9)

💅 ir_rc6_decode(9) — the Kernel API Manual, bestie edition ✨

okay so picture this: ir_rc6_decode() — the little function whose whole entire job is Decode one RC6 pulse or space 🎀 like that's it, that's the gig, and honestly? iconic.

---

✨ SYNOPSIS ✨

int ir_rc6_decode (struct rc_dev *dev , struct ir_raw_event ev );

literally just one line, no drama, no cap 🫶

---

🌸 ARGUMENTS 🌸

• dev — the struct rc_dev descriptor of the device 💖 this is the main character, the remote-control device struct itself.
• ev — the struct ir_raw_event descriptor of the pulse/space 🌈 like which pulse or space are we even talking about, this one, this is the one.

---

🦋 DESCRIPTION 🦋

so the whole vibe check here is: this function returns -EINVAL if the pulse violates the state machine 😭💀

that's the entire tea. if the incoming pulse doesn't play nice with the state machine's rules, you get -EINVAL handed right back to you. not me being dramatic, that's genuinely what it does 👑

lowkey important: that -EINVAL is the error path, so don't be surprised when it shows up — it means the state machine said "girl, no" 🙈
