✨ snd_pcm_format_linear(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for snd_pcm_format_linear — yes it's a 9th-section page, yes it's a kernel function, yes we're doing this 💅

---

🌸 NAME 🌸

snd_pcm_format_linear — the vibe check that tells you whether a PCM format is linear 🔥

---

🎀 SYNOPSIS 🎀

int snd_pcm_format_linear (snd_pcm_format_t format );

that's it. one function, one argument, no drama 🦋

---

💖 ARGUMENTS 💖

• format — the format to check 👀 like, the actual PCM format you're side-eyeing. that's the whole input, she's lowkey simple and we love her for it.

---

⭐ RETURN ⭐

returns 1 if the given PCM format is linear, 0 if not. that's it, that's the answer — a little yes/no binary moment, no cap 🫶

fr fr it only ever hands you back 1 or 0, so don't go looking for negative error codes here, she's not that kind of function 💀
