max_pow_of_two_factor(9)

💖 max_pow_of_two_factor(9) — the kernel API glow-up 🎀

okay bestie, welcome to the max_pow_of_two_factor(9) page from the Kernel API Manual ✨ this one is short but she's iconic, ngl.

---

🌸 NAME 🌸

max_pow_of_two_factor — returns the highest power-of-2 factor, periodt 💅

---

⭐ SYNOPSIS ⭐

unsigned int max_pow_of_two_factor (unsigned int n );

like, you hand her an unsigned int and she hands you back an unsigned int. that's the whole vibe 🦋

---

🎀 ARGUMENTS 🎀

• n — parameter 🙈 that's literally the whole description the original gives, so i'm not gonna invent lore for it. she's just n, the argument, the main character of this function 💜

---

👑 DESCRIPTION 👑

so what she does is: find the highest power-of-2 which is evenly divisible into n 🔥 like genuinely, evenly divisible, no remainder crumbs left over.

and the special-case tea ☕: 0 is returned for n == 0 or 1. both of those get you a 0, no cap 💀

careful bestie — that 0 back is a real return value, not an error code, so don't go reading drama into it that isn't there 🫶
