STRUCT EC_RESPONSE_CEC_GET(9)

💜 struct ec_response_cec_get(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel API manual (iconic behaviour, honestly) and you hit struct ec_response_cec_get, which is the CEC parameters get response. That's the whole vibe. It's the little reply struct the EC sends back when you ask it about CEC stuff, and she is tiny but she is doing her job. 🎀

✨ SYNOPSIS ✨

struct ec_response_cec_get {
    uint8_t val;
 };

yes bestie that's it, one single field, minimalism ate 💅

🌸 Members 🌸

• val — okay so this one field is a little shapeshifter and which personality she shows depends entirely on what cmd was:
  • if cmd was CEC_CMD_ENABLE, then val is 0 when CEC is disabled, or 1 when CEC functionality is enabled 🔥
  • if cmd was CEC_CMD_LOGICAL_ADDRESS, then val encodes the configured logical address — a number between 0 and 15 — or 0xff if it's unregistered 🙈

ngl the double-duty thing is giving main character energy, so keep track of which cmd you sent or you'll misread the whole vibe check 💀
