STRUCT EC_PARAMS_CEC_WRITE(9)

💅 struct ec_params_cec_write(9) — Kernel API Manual, but make it cute

okay so bestie, welcome to the kernel API manual ✨ this one's all about struct ec_params_cec_write, and it's literally the little messenger that carries your bytes over to the CEC bus. no cap, that's the whole vibe. 🎀

🌸 NAME 🌸

struct ec_params_cec_write — the message you send when you wanna write stuff to the CEC bus 💌

✨ SYNOPSIS ✨

like, here's the whole struct, and yes it's exactly this and nothing more, she's lowkey minimalist:

struct ec_params_cec_write {
    uint8_t msg[MAX_CEC_MSG_LEN];
 };
