💅 snd_pcm_format_width(9) — from the Kernel API Manual ✨

okay so bestie, listen — this is snd_pcm_format_width, a little function from the Kernel API Manual that does exactly one iconic thing: it tells you how wide a PCM format is in bits. that's it. that's the whole vibe. 🎀

---

🦋 NAME 🦋

snd_pcm_format_width — return the bit-width of the format. literally just that, no cap 💖

---

✨ SYNOPSIS ✨

int snd_pcm_format_width (snd_pcm_format_t format );

yep, that's the whole signature, she's cute and she's short 🫶

---

🌸 ARGUMENTS 🌸

• format — the format you want to check 👀 that's the one and only argument, bestie, just hand over the format and let her do her thing.

⭐ RETURN ⭐

she gives you back the bit-width of the format — slay 💅 — or, if the format is unknown, a negative error code. so like, if you get a negative number back, that's your sign the format wasn't a real one 😭 no guessing, check it fr fr.
