q6asm_open_read(9)

💖 q6asm_open_read — the manual page, but make it make sense 💖

okay so bestie, this is q6asm_open_read(9) from the Kernel API Manual — yes, section 9, we're in kernel-land now, put your seatbelt on 🎀

---

✨ NAME ✨

q6asm_open_read — open an audio client for reading 🎧 like, you're about to pull audio out, not push it in. icon behaviour only.

---

🦋 SYNOPSIS 🦋

int q6asm_open_read (struct audio_client *ac , uint32_t stream_id ,
       uint32_t format , uint16_t bits_per_sample );

that's the whole vibe. returns an int, takes four things. no cap, that's it 💅

---

🌸 ARGUMENTS 🌸

here's the tea on every single parameter, no skipping, we don't do that here 🫶

• ac — the audio client pointer. yes bestie, that audio client. the main character of this whole function 🫡
• stream_id — the stream id. it's the id... of the stream. identifying it. iconic behaviour honestly.
• format — the audio sample format. this is where you tell it what kind of audio situation we're dealing with ✨
• bits_per_sample — bits per sample. literally how many bits go into one little sample 🍓 it's a uint16_t, so be normal about it.

---

⭐ RETURN ⭐

so what comes back? 👀

• a negative value if something went wrong 😭 (on error, bestie, that's the bad timeline)
• zero on success 🎉 periodt.

that's it. negative = sad. zero = slay.
