STRUCT SND_COMPR_AVAIL64(9)

✨ struct snd_compr_avail64 — the kernel API manual, but make it make sense ✨

okay so bestie, you're looking at struct snd_compr_avail64 from the Kernel API Manual, and honestly? she's a little icon. lowkey she's just an avail descriptor, but the tstamp in there is in 64 bit format, which is the whole point, iykyk 💅

🌸 NAME 🌸

struct snd_compr_avail64 — avail descriptor with tstamp in 64 bit format

periodt. that's the vibe. descriptor? avail. tstamp? 64 bit. no notes. ✨

---

🎀 SYNOPSIS 🎀

the whole struct, exactly as she is, no cap:

struct snd_compr_avail64 {
    __u64 avail;
    struct snd_compr_tstamp64 tstamp;
 };

like… three lines and she's already serving struct realness 🫶

🦋 Members 🦋

• avail — the number of bytes available in the ring buffer for writing/reading. yes bestie, writing/reading — she does both, main character energy fr fr 🔥
• tstamp — timestamp information. that's it, that's the info 🌸

---

💜 SEE ALSO 💜

go look at the kernel file ./include/uapi/sound/compress_offload.h — that's where the whole friend group lives, and honestly the whole squad is iconic:

• struct snd_compressed_buffer(9)
• struct snd_compr_params(9)
• struct snd_compr_tstamp(9)
• struct snd_compr_tstamp64(9)
• struct snd_compr_avail(9)

• struct snd_compr_metadata(9)
• struct snd_compr_task(9)
• enum snd_compr_state(9)
• struct snd_compr_task_status(9)

not me listing all twelve of them 💀 but like, every single one matters, bestie — go read them, they ate 👑

and that's the whole page, bestie — no crumbs left behind 🎀✨🌸💅

this masterpiece of documentation came out of ./include/uapi/sound in October 2026, and it's still filed under struct snd_compr_avail64(9). slay, honestly. 💖🦋
