q6asm_unmap_memory_regions(9)

💅 q6asm_unmap_memory_regions(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the Kernel API Manual and you've stumbled onto q6asm_unmap_memory_regions(9). say hi, she's the cleanup queen 👑 — she unmaps memory regions in the dsp. that's it, that's the whole vibe. no cap.

---

✨ NAME ✨

q6asm_unmap_memory_regions — unmap memory regions in the dsp. literally the undoing of the mapping, the "you don't have to go home but you can't stay here" of DSP memory 🫶

---

🌸 SYNOPSIS 🌸

int q6asm_unmap_memory_regions (unsigned int dir , struct audio_client
*ac );

yup, that's the whole signature — she takes two things and returns an int. iconic behavior honestly.

---

🎀 ARGUMENTS 🎀

• dir — direction of audio stream 🌈 like, which way the audio is flowing, bestie. that's the whole description, she's mysterious like that.
• ac — audio client instance 💖 (the original spells it "instanace" and honestly? relatable. typos are a mood. anyway — it's your audio client instance.)

---

⭐ RETURN ⭐

Will be an negative value on failure or zero on success. so: 0 = slay ✨, anything negative = not slay 😭. keep an eye on that return value, fr fr.

🚨 no cap on this one: negative means something went wrong. do not ignore it and pretend everything's fine, that's not the main character energy we're going for.
