STRUCT SDCA_GE_CONTROL(9)

🎀 struct sdca_ge_control(9) 🎀

okay so bestie, we're deep in the Kernel API Manual today and honestly? this one's a lil cutie. it's a tiny lil struct living its best life in the sound subsystem, and it's literally just one entry in the affected controls list. that's it. that's the whole vibe. ✨

---

🌸 NAME 🌸

struct sdca_ge_control — no cap, it's a control entry in the affected controls list. that's the whole job description, and it does it slayfully 💅

---

🦋 SYNOPSIS 🦋

lowkey the entire struct is four little ints and honestly it's giving minimalism:

struct sdca_ge_control {
    int id;
    int sel;
    int cn;
    int val;
 };

---

💖 Members 💖

ooh okay now we get to the good part, the actual fields, let's go field by field, no skipping, periodt:

• id — the Entity ID of the Control affected. like, which entity are we even talking about bestie, this is how you know 🫶
• sel — the Control Selector of the Control affected. the selector of it. yes it's basically the same sentence and yes i'm telling you anyway.
• cn — the Control Number of the Control affected. the number. of the control. that's affected. iconic of it honestly.
• val — the Value written to Control for this Mode. this is the actual payload, the main character, the thing that gets written when this Mode comes through 🔥

fr fr, all four of these describe the Control affected — the val is just the one that actually carries data into it for this Mode. 💜
