🌸 NAME 🌸

amdtp_stream_pcm_running — check PCM substream is running or not 👀

---

✨ SYNOPSIS ✨

bool amdtp_stream_pcm_running (struct amdtp_stream *s );

like, that's it. that's the whole vibe. she takes one arg and hands you a bool. no cap. 🫶

---

🎀 ARGUMENTS 🎀

• s — the AMDTP stream 💖 literally just the stream you're checking on. your blorbo. your subject of inquiry. the one you're asking about.

---

🦋 DESCRIPTION 🦋

so here's the tea: if this function returns true, the PCM substream in the AMDTP stream is running. 🔥 that's the whole story, bestie.

and if it returns false? well… then she's not running. and you can lowkey infer that from the true case iykyk 😭 the manpage said what it said and it ate. periodt.

ngl this is a "say it once, say it right" kind of function. no hidden lore. no secret flags. just a boolean with immaculate vibes. 💀
