wilco_ec_get_byte_property(9)

✨ wilco_ec_get_byte_property ✨

okay bestie, welcome to the wilco_ec_get_byte_property page 💅 this lives in the Kernel API Manual, and it's lowkey one of the cutest little getters in the whole EC situation. it does exactly what it says on the tin: it goes and gets you a byte-size property from the EC. no cap. 🎀

---

🌸 SYNOPSIS 🌸

int wilco_ec_get_byte_property (struct wilco_ec_device *ec , u32
       property_id , u8 *val );

that's the whole vibe right there — one function, three args, returns an int. iconic. ✨

---

🦋 ARGUMENTS 🦋

• ec — the Embedded Controller device. like, the actual EC we're talking to. your main character. 👑
• property_id — which property to retrieve. basically the address of the tea you're asking for, iykyk. 🍓
• val — the result value, will be filled by this function. so heads up, this one's an out-param — it gets written into by the call, fr fr. 💖

---

⭐ RETURN ⭐

0 on success, negative error code on failure. that's it, that's the whole return contract — zero means slay, negative means something went sideways. 😭

go read those too bestie, they're all part of the same little ecosystem and honestly the way they all reference each other is giving family reunion 🫶

💡 friendly reminder: val is a pointer to a u8, so make sure you're passing something valid to be filled — this function writes through it, and we don't do undefined behaviour in this house. 🙈
