samples_to_bytes(9)

💖 samples_to_bytes(9) 💖

okay so bestie, this page is from the Kernel API Manual, and it's literally about converting a size from samples to bytes. that's the whole vibe. no cap ✨

🎀 NAME 🎀

<hotpink>samples_to_bytes</hotpink> — unit conversion of the size from samples to bytes 💅

🦋 SYNOPSIS 🦋

the way this function gets called is exactly this, bestie:

ssize_t samples_to_bytes (struct snd_pcm_runtime *runtime , ssize_t size
);

🌸 ARGUMENTS 🌸

• runtime — PCM runtime instance. that's the PCM runtime you're working with 🫶
• size — size in samples. yes, samples, not bytes — that's the whole point lol 🎀

✨ RETURN ✨

it returns the byte size. periodt 💅

okay bye bestie 🫶 — this page came from ./include/sound, dated October 2026, and it's samples_to_bytes(9). mwah 💋✨
