STRUCT CEC_CAPS(9)

💅 NAME

struct cec_caps — the CEC capabilities structure, bestie. It's giving "here's what this device can actually do." ✨

✨ SYNOPSIS

struct cec_caps {
    char driver[32];
    char name[32];
    __u32 available_log_addrs;
    __u32 capabilities;
    __u32 version;
 };

🎀 Members

Okay so let's go through the members one by one, no skips, fr fr 👑

• driver — the name of the CEC device driver. That's your driver's whole identity, periodt.
• name — the name of the CEC device. Heads up though: driver + name must be unique — together they're the one-of-a-kind combo, so don't be out here duplicating, iykyk 🫶
• available_log_addrs — the number of available logical addresses.
• capabilities — the capabilities of the CEC adapter. Literally the whole vibe check of what it can do 💅
• version — the version of the CEC adapter framework.

Quick little note bestie: available_log_addrs, capabilities and version are all __u32, and driver and name are char[32] each — the exact types matter, don't come for me 🌸
