snd_interval_refine(9)

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

Okay so picture this: you're deep in the Kernel API Manual, page snd_interval_refine(9), and you need to refine the interval value of configurator. That's the whole vibe. Let's get into it ✨

---

🌸 SYNOPSIS 🌸

int snd_interval_refine (struct snd_interval *i , const struct
       snd_interval *v );

Literally the whole function signature, no notes 💅

---

🫶 ARGUMENTS 🫶

• i — the interval value to refine. this is the one getting a glow-up ✨
• v — the interval value to refer to. this is the reference point, the icon, the blueprint 👑

---

🔥 DESCRIPTION 🔥

So what does it do? It refines the interval value with the reference value. The interval gets changed to the range that satisfies both intervals — like when you and your bestie both agree on a plan and suddenly it's actually happening 🫶

And bestie, the interval status (min, max, integer, etc.) gets evaluated. All of it. Every lil status. No cap 💯

---

⭐ RETURN ⭐

• Positive if the value is changed — slay, something happened 💅
• Zero if it's not changed — it's giving "no thoughts, head empty" 😭
• a negative error code — something went wrong, and we simply do not claim that energy 🙈

okay that's the page, mwah 💖 This lil masterpiece lives in ./sound/core, dated October 2026 — that's the source/version and date, bestie, noted and cherished. Go refine some intervals, you absolute main character 👑✨
