xbc_for_each_key_value(9)

📦 version 7.3.1, in nixpkgs unstable

✨ xbc_for_each_key_value ✨ (that's section 9 of the Kernel API Manual, bestie!)

okay so real talk, this one is a kernel API page and it's giving "tiny function, huge main character energy" 💅 it lives in the Kernel API Manual, section 9, and honestly? it's a little gem.

🌸 NAME 🌸

xbc_for_each_key_value — the one that iterates key-value pairs, fr fr 🔥

🎀 SYNOPSIS 🎀

xbc_for_each_key_value (knode , value );

that's it. that's the whole vibe. two args, zero drama ✨

🦋 ARGUMENTS 🦋

  • knode — the iterated key node 🗝️ this is where the current key node lands while you're looping
  • value — the iterated value string 🧵 and this is where the matching value string lands

💖 DESCRIPTION 💖

bestie listen, it's actually so simple. this iterates over key-value pairs across the whole entire XBC tree 🌳 like, the whole tree, no cap.

each key node gets stored in knode, and each value string gets stored in value, respectively 🫶 so every trip around the loop hands you a fresh pair and you just do your thing. iconic behaviour, honestly 💅

🌈 SEE ALSO 🌈

kernel file ./include/linux/bootconfig.h — go read it, it's lowkey the whole lore drop 📖✨ and while you're at it, these besties are all in the same friend group:

and that's the whole page, mwah 💋 it comes to you straight from ./include/linux, dated October 2026, in the Kernel API Manual — slay, go iterate some key-value pairs, you've got this 👑🎀
