🎀 ir_nec_decode 🎀

okay so this is a page from the Kernel API Manual, and it's about one (1) little function that does one (1) little job, and honestly? she's doing great 💅

---

✨ NAME ✨

ir_nec_decode — decodes, like, exactly one NEC pulse or space. one. single. pulse. or space. that's the whole gig bestie 🫶

---

🌸 SYNOPSIS 🌸

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

---

🦋 ARGUMENTS 🦋

• dev — the struct rc_dev descriptor of the device 💖 like, the device in question, in struct form
• ev — the struct ir_raw_event descriptor of the pulse/space ✨ the actual little pulse-or-space being handed over

---

💀 DESCRIPTION 💀

so here's the vibe check: this function returns -EINVAL if the pulse violates the state machine 😭 that's it, that's the description, no notes.

lowkey important though — if your pulse is out here breaking the state machine rules, you get -EINVAL and that's the consequence, no cap 🚩
