💅 mask_apply_and_normalize(9) — the glow-up edition

okay so bestie, welcome to the Kernel API Manual ✨ this one's a tiny little function that does one (1) thing and honestly? it ate. let's get into it 🎀

---

🌸 NAME 🌸

mask_apply_and_normalize</p> — applies mask on val and normalize the result 💫

like… it masks, it normalizes, it serves. that's the whole vibe check.

---

✨ SYNOPSIS ✨

u32 mask_apply_and_normalize (u32 val , u32 mask );

two u32 inputs, one u32 output. minimal, iconic, no notes. 👑

🫶 ARGUMENTS 🫶

• val — value. that's it, that's the parameter. the raw number going in 💖
• mask — mask to apply and to normalize with. it does double duty fr fr, first it masks, then it normalizes. main character energy 🌟

---

🦋 DESCRIPTION 🦋

so here's the tea: the normalization is based on the first set bit in the mask 👀

that's the whole description, no cap. the first set bit is the anchor point, everything else gets normalized relative to it. lowkey elegant, highkey underrated 💅

💀 RETURN 💀

• the extracted value 🌈

that's what you get back — the extracted value. no error codes, no weird sentinel values, just the extraction. slay ✨
