✨ for_each_set_clump8(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a macro and it's honestly so iconic — it walks your bitmap in 8-bit clumps and only stops at the clumps that have set bits in them. no cap, it's giving "selective scrolling" energy 👑

🌸 NAME 🌸

for_each_set_clump8 — iterate over bitmap for each 8-bit clump with set bits 🎀

like, literally: for every 8-bit clump that has any set bits, you get a turn. the ones that are all zeroes? they don't get an invite to the group chat 🙈

🦋 SYNOPSIS 🦋

for_each_set_clump8 (start , clump , bits , size );

💅 ARGUMENTS 💅

  • start — bit offset to start the search from, and also where the current iteration offset gets stored 🔥 so it's both the starting point and the lil bookmark that moves along as you go. main character of the argument list ngl.
  • clump — the location where a copy of the current 8-bit clump gets stored 🍓 that's where you peek at what you found.
  • bits — the bitmap address you're basing the search on 🌈 your actual data, your vibe.
  • size — the bitmap size, measured in number of bits ✨ not bytes, not clumps, bits. don't get it twisted fr fr.
