💅 snd_pcm_format_size(9) 💅

okay bestie, welcome to this lil page from the Kernel API Manual — it's short, it's useful, and it's literally about figuring out how many bytes your samples take up. slay. 🎀

✨ NAME ✨

snd_pcm_format_size — return the byte size of samples on the given format. no cap, that's the whole gig. 💖

🌸 SYNOPSIS 🌸

ssize_t snd_pcm_format_size (snd_pcm_format_t format , size_t samples );

🦋 ARGUMENTS 🦋

  • format — the format to check. yes bestie, the format in question 👀
  • samples — sampling rate. that's what the page says, so that's what we're telling you 💅

⭐ RETURN ⭐

The byte size of the given samples for the format, or a negative error code if the format is unknown. so if it's a mystery format, you get a negative error code — not a vibe, but useful 😭
