cik_create_bitmask(9)

💅 cik_create_bitmask(9) — like, the kernel API manual, bestie

Ok so real talk: this is cik_create_bitmask from section 9 of the Kernel API Manual, and she is a whole mood — tiny function, immaculate vibes. Let's get into it ✨

---

🌸 NAME 🌸

cik_create_bitmask — create a bitmask. That's it. That's the whole job. She builds a mask. Iconic behavior, no notes 💅

---

🦋 SYNOPSIS 🦋

u32 cik_create_bitmask (u32 bit_width );

---

🎀 ARGUMENTS 🎀

• bit_width — the length of the mask. Yes bestie, length, she's variable and she's proud of it 🫶

---

✨ DESCRIPTION ✨

So what does she actually do? She creates a variable length bit mask (CIK), and then — plot twist — returns the bitmask. That's the entire arc. Beginning, middle, end. Main character energy from start to finish 👑

ngl this is one of those pages where the function does exactly what the name says and the docs are like "yeah. that." — respect honestly 🙈
