💅 BITOPS(3) — the bitops girlies' edition

okay so bestie, this one is a page from the Library Functions Manual — yes, the actual manual, and yes, we're gonna read it together. it's about bitops, and honestly? it ate. 🎀

✨ NAME ✨

bitops — functions related to bits and integers 🧚

like, the whole header is just vibing around bits and integers. that's the assignment. that's the lore.

🌸 SYNOPSIS 🌸

#include <sys/bitops.h>

that's it. that's the whole synopsis. one include and you're in. 🫶

💖 DESCRIPTION 💖

okay so the <sys/bitops.h> header provides macros and static inline functions related to bits and integers. highkey iconic of it.

among these are, and I'm literally quoting the roster because every single one matters:

  • bitmap(3) — bitmap manipulation macros 🎀
  • fast_divide32(3) — a function for fast 32-bit division ⚡
  • ffs32(3) — functions to find the first and last set bit in integers of type uint32_t and uint64_t 🔍
  • ilog2(3) — a macro for binary logarithm 📐

that's the whole squad. go click their pages, iykyk. 👑

🌈 HISTORY 🌈

the <sys/bitops.h> header first appeared in NetBSD 4.0. so it's got history, it's got range, it's giving legacy main character energy. ⭐

and that's the whole page, bestie — no cap, every option-free detail preserved exactly as the manual intended. 🍓

source/version: Debian. dated: December 4, 2012. so if you're reading this in 2012, hi, you're literally early to the bitops renaissance. mwah 💅✨
