STRUCT SOF_IPC4_TUPLE(9)

💅 struct sof_ipc4_tuple(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's short and sweet — it's giving "little struct, big responsibilities" and i'm obsessed 🫶

---

🌸 NAME 🌸

struct sof_ipc4_tuple — a generic type/ID + parameter tuple, fr fr 🎀

---

✨ SYNOPSIS ✨

struct sof_ipc4_tuple {
    uint32_t type;
    uint32_t size;
    uint32_t value[];
};

like… that's it. three members. she's minimal, she's iconic, she's the tuple 💅

---

🦋 Members 🦋

• type — the type/ID, aka "what flavour of thing is this" 🌈 it's the label on the box, iykyk
• size — the size of the value array, and yes bestie it's measured in bytes (not elements!! don't do that to yourself 😭)
• value — the actual value for the given type 💖 she's flexible, she's a [] flexible array member, she contains multitudes

ngl the way value is a flexible array member means the bytes just keep going after the struct — so size is literally your only clue about how much is actually there. trust her. read the size. 🙈
