q6asm_cmd(9)

💅 q6asm_cmd(9) 💅

okay bestie, so this is a page straight out of the Kernel API Manual and honestly? it's a little cutie. we're talking about q6asm_cmd — the function that runs a command on an audio client. that's it, that's the whole vibe. let's get into it. 🎀

---

✨ SYNOPSIS ✨

int q6asm_cmd (struct audio_client *ac , uint32_t stream_id , int cmd );

like, look at her. three args, returns an int. simple, iconic, no notes. 🫶

---

🌸 ARGUMENTS 🌸

• ac — the audio client pointer, aka your main character. hand her over and we're in business. ✨
• stream_id — the stream id. yes, exactly what it sounds like. it's a uint32_t, it identifies the stream, we love a straightforward queen. 💜
• cmd — the command to run on the audio client. an int. you pick it, it runs it. iykyk. 💅

---

🔥 RETURN 🔥

so here's the vibe check on the return value:

• it'll be a negative value if something goes wrong 😭 (error, bestie, not great)
• or zero on success ✨ (slay, we ate)

ngl, "negative on error, zero on success" is the classic Kernel API move — no cap, that's just how she operates. keep an eye on that return fr fr.
