STRUCT SND_COMPR_STREAM(9)

💅 struct snd_compr_stream(9)

okay so bestie, welcome to the kernel API manual — specifically the page for struct snd_compr_stream, which lives in the Kernel API Manual. yes this is the compressed-stream glow-up you've been waiting for. buckle up 🎀

✨ NAME ✨

struct snd_compr_stream — the compressed stream struct itself. that's it, that's the vibe. it's giving core data structure energy 👑

🌸 SYNOPSIS 🌸

here she is, in all her glory — copy this exactly, no typos, i'm watching 👀

struct snd_compr_stream {
    const char *name;
    struct snd_compr_ops *ops;
    struct snd_compr_runtime *runtime;
    struct snd_compr *device;
    struct delayed_work error_work;
    enum snd_compr_direction direction;
    bool metadata_set;
    bool next_track;
    bool partial_drain;
    bool pause_in_draining;
    void *private_data;
    struct snd_dma_buffer dma_buffer;
 };

🦋 Members 🦋

okay now the actual members, one by one, no skipping, we don't do that here 💖

• name — the device name. literally just the name. iconic of her.
• ops — a pointer to the DSP callbacks. the whole personality lives here ngl.
• runtime — a pointer to the runtime structure. yes, another struct, it's structs all the way down 🫶
• device — device pointer. you know the drill.
• error_work — delayed work used when closing the stream due to an error 😭 so when things go wrong, this is the cleanup crew.
• direction — the stream direction, playback/recording. which way the audio is flowing, bestie.
• metadata_set — metadata set flag, true when set. yes the name is the description, she's self-aware 💅
• next_track — has userspace signal next track transition, true when set. bop incoming 🔥
• partial_drain — undergoing partial_drain for the stream, true when set. mid-drain main character moment.
• pause_in_draining — paused during draining state, true when set. pausing while draining, the multitasking queen that she is ✨
• private_data — a pointer to DSP private data. secrets 🤫 keep it private, hence the name.
• dma_buffer — the allocated buffer, if any. if any!! sometimes there just isn't one and that's fine 🍓
