STRUCT EC_PARAMS_CEC_READ(9)

🦋 struct ec_params_cec_read(9) — Kernel API Manual 🦋

okay so bestie, welcome to the kernel API manual, and today's main character is struct ec_params_cec_read(9). she's small, she's cute, she has exactly one member, and she's here to help you read a message off the CEC bus. no cap. 💅

---

✨ NAME ✨

struct ec_params_cec_read — literally just: Read a message from the CEC bus. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

here's the whole entire struct, bestie, look how tiny she is:

struct ec_params_cec_read {
    uint8_t port;
 };

yes that's it. that's the girl. ✨

---

👑 Members 👑

• port — the CEC port you're reading a message on. that's the one (1) thing this struct asks you for. pick your port, bestie, and go read that message. 🫶

💀 real talk for one sec: if you came here looking for the other CEC structs, they're all up there in that list — ec_params_cec_write, ec_params_cec_write_v1, ec_response_cec_read, ec_params_cec_set, ec_params_cec_get, ec_response_cec_get and ec_response_cec_port_count. the whole cec friend group is accounted for. 🧚

and that's the page!! 💖 stay slay, read your CEC messages responsibly, and remember: one uint8_t port, infinite possibilities. 🦋
