ENUM SDCA_IT_CONTROLS(9)

💅 enum sdca_it_controls(9) — the Kernel API Manual moment

okay so bestie, welcome to enum sdca_it_controls(9), straight out of the Kernel API Manual ✨ this is the little enum that holds all the SDCA Controls for the Input Terminal, and honestly? it's giving "short but iconic." 🎀

🌸 NAME 🌸

enum sdca_it_controls — SDCA Controls for Input Terminal. that's it, that's the whole vibe 💖

---

✨ SYNOPSIS ✨

enum sdca_it_controls {
    SDCA_CTL_IT_MIC_BIAS ,
    SDCA_CTL_IT_USAGE ,
    SDCA_CTL_IT_LATENCY ,
    SDCA_CTL_IT_CLUSTERINDEX ,
    SDCA_CTL_IT_DATAPORT_SELECTOR ,
    SDCA_CTL_IT_MATCHING_GUID ,
    SDCA_CTL_IT_KEEP_ALIVE ,
    SDCA_CTL_IT_NDAI_STREAM ,
    SDCA_CTL_IT_NDAI_CATEGORY ,
    SDCA_CTL_IT_NDAI_CODINGTYPE ,
    SDCA_CTL_IT_NDAI_PACKETTYPE

};

like, copy it exactly okay, don't be cute with the commas, they're part of the fit 😭

🦋 Constants 🦋

so here's the thing bestie — every single one of these is marked -- undescribed -- in the doc, so like, the source of truth is being mysterious on purpose 🙈 i'm not gonna make stuff up for you (no cap, that would be a betrayal), so here's the full roster, each one living its undescribed truth:

• SDCA_CTL_IT_MIC_BIAS — -- undescribed --
• SDCA_CTL_IT_USAGE — -- undescribed --
• SDCA_CTL_IT_LATENCY — -- undescribed --
• SDCA_CTL_IT_CLUSTERINDEX — -- undescribed --
• SDCA_CTL_IT_DATAPORT_SELECTOR — -- undescribed --
• SDCA_CTL_IT_MATCHING_GUID — -- undescribed --
• SDCA_CTL_IT_KEEP_ALIVE — -- undescribed --
• SDCA_CTL_IT_NDAI_STREAM — -- undescribed --
• SDCA_CTL_IT_NDAI_CATEGORY — -- undescribed --
• SDCA_CTL_IT_NDAI_CODINGTYPE — -- undescribed --
• SDCA_CTL_IT_NDAI_PACKETTYPE — -- undescribed --

bestie if you need the lore on what each selector actually does, you're gonna have to go read the spec, because this manpage is NOT spilling 🫶

🌈 Description 🌈

these are the Control Selectors for the Input Terminal, and the receipts are the SDCA specification v1.0, section 6.2.1.3 👑 that's the main character source, periodt.
