✨ snd_pcm_hw_params_bits(9) ✨

okay so bestie, we're in the Kernel API Manual rn and this page is literally about snd_pcm_hw_params_bits 💅 it's a tiny one but it's iconic, no cap.

---

🎀 NAME 🎀

snd_pcm_hw_params_bits — get the number of bits per the sample. that's it. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

int snd_pcm_hw_params_bits (const struct snd_pcm_hw_params *p );

---

💖 ARGUMENTS 💖

• p — hardware parameters. yes that's the whole description, she's lowkey mysterious like that 🙈

---

⭐ RETURN ⭐

it hands you back the number of bits per sample, and the way it decides is based on the format, the subformat and msbits that the specified hw params has. so it's not just vibes — it's actually reading all three of those, periodt 🔥
