snd_compr_se...ntime_buffer(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so this is snd_compr_set_runtime_buffer — literally the function that sets the Compress runtime buffer. that's the whole vibe. main character energy for your audio compression stream setup 🎧✨

so yeah, you're reading the page for snd_compr_se...ntime_buffer(9) out of the Kernel API Manual — welcome bestie, stay a while 🫶

✨ SYNOPSIS ✨

void snd_compr_set_runtime_buffer (struct snd_compr_stream *stream ,
struct snd_dma_buffer *bufp );

that's it. that's the whole call. two args, no return value, no drama 💅

🎀 ARGUMENTS 🎀

  • stream — the compress stream you're setting stuff on. like, the actual thing being configured. the icon 👑
  • bufp — the buffer information. and listen, this one's got a secret: pass NULL here and it clears everything instead. so NULL is not a mistake, it's a mood 🫧

🌸 DESCRIPTION 🌸

so here's what's happening, no cap: when bufp is non-NULL, it just copies the buffer information over to the runtime buffer. super chill, super straightforward 💖

but when bufp is NULL? it clears the current buffer information instead. so it's giving "two modes, one function" and honestly? we love a versatile queen 🎀

that's literally the whole thing. short and sweet, which is rare for a kernel function ngl 😭

🦋 SEE ALSO 🦋

the kernel file lives at ./include/sound/compress_driver.h — go read it, iykyk 📖

and then the whole friend group of structs and friends, all repping their (9) pages:

that's a whole lotta snd_compr besties fr fr 🌈

reminder bestie: NULL for bufp is a legit "clear it out" move, not a typo. don't come for me if you forget 💀

mwah 💋 that's the page — sourced from ./include/sound, dated October 2026, and yes it's still called snd_compr_se...ntime_buffer(9) (the truncation is iconic at this point, we don't question it 🙈). go set some buffers, slay, periodt. 🦋✨
