snd_interval_ranges(9)

✨ snd_interval_ranges(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual — it's called snd_interval_ranges, and it's lowkey the glow-up artist for interval values 💅

---

🌸 NAME 🌸

snd_interval_ranges — refine the interval value from the list of ranges

---

🎀 SYNOPSIS 🎀

int snd_interval_ranges (struct snd_interval *i , unsigned int count ,
       const struct snd_interval *ranges , unsigned int mask );

no cap, that's the whole signature 👑

---

🦋 ARGUMENTS 🦋

• i — the interval value to refine. this is the main character we're giving a makeover to 💖
• count — the number of elements in the list of ranges, fr fr
• ranges — the ranges list itself
• mask — the bit-mask to evaluate ✨

---

🌈 DESCRIPTION 🌈

So here's the vibe: it refines the interval value from the list of ranges. That's it, that's the whole thing 🫶

And when mask is non-zero, only the elements corresponding to bit 1 are evaluated. like, it's selective. it has standards. periodt 💅

---

⭐ RETURN ⭐

• Positive if the value is changed 💫
• zero if it's not changed 😌
• or a negative error code 😭
