find_next_or_bit(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

okay so bestie, welcome to the find_next_or_bit(9) page from the Kernel API Manual 💅. We're finding set bits, we're keeping every detail, and we're doing it with main character energy. Let's go ✨

find_next_or_bit — find the next set bit in either memory regions 💅

✨ SYNOPSIS ✨

unsigned long find_next_or_bit (const unsigned long *addr1 , const
       const unsigned long *addr2 , unsigned long size , unsigned long offset );

That's the signature exactly as written — double const and all, no cap 🫶.

💖 ARGUMENTS 💖

  • addr1 — the first address to base the search on 🔍
  • addr2 — the second address to base the search on 🔍
  • size — the bitmap size in bits 📏
  • offset — the bitnumber to start searching at 👀

🔥 DESCRIPTION 🔥

okay so the tea ☕: find_next_or_bit returns the bit number for the next set bit. If no bits are set, it returns size. That's the whole plot — no cap, periodt 💅.

So if you're hunting and there's literally nothing set, size is what comes back 🫶.
