STRUCT SND_COMPR_TASK_STATUS(9)

okay bestie, we’re in the Kernel API Manual, section 9, and today’s main character is struct snd_compr_task_status(9) — the task status struct. it’s giving kernel-internals chic 💅

💖 NAME 💖

struct snd_compr_task_status - task status. that’s the whole name, no cap. periodt. 🎀

✨ SYNOPSIS ✨

here’s the exact struct, bestie — just read her shape:

       struct snd_compr_task_status {
           __u64 seqno;
           __u64 input_size;
           __u64 output_size;
           __u32 output_flags;
           __u8 state;
           __u8 reserved[15];
        };

👑 Members 👑

okay so every field is lowkey important, and here’s the tea:

• seqno — the sequence number, aka the task identifier. iykyk 🎀
• input_size — filled data in bytes, and it comes from user space. 💖
• output_size — filled data in bytes, and this one comes from the driver. 🦋
• output_flags — reserved for future, all zeros, straight from the driver. do not come for her yet ✨
• state — the actual task state, using the SND_COMPRESS_TASK_STATE_* constants. 👑
• reserved — reserved for future extension. she’s just holding space 🫶
