cec_msg_opcode(9)

💅 cec_msg_opcode(9) — like, the Kernel API Manual era 🎀

okay bestie, welcome to cec_msg_opcode — it's a kernel API page, it lives in the Kernel API Manual, and it's about to tell you which opcode a CEC message is carrying. tiny function, big main character energy ✨

---

🌸 NAME 🌸

cec_msg_opcode — return the opcode of the message, -1 for poll 🫶

yep, that's the whole vibe. you ask it what opcode the message has, and if this thing is a poll, it hits you with a -1. no cap. 💀

---

✨ SYNOPSIS ✨

int cec_msg_opcode (const struct cec_msg *msg );

literally that's it. one function, one argument, int coming back at you. iconic.

---

🦋 ARGUMENTS 🦋

• msg — the message structure. that's the one you're passing in, and yes it's a const struct cec_msg *, so this function is not about to go messing with your data. respectful king behavior 👑💜
