✨ kho_radix_walk_tree(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 today we're doing kho_radix_walk_tree, and honestly? it's giving "scenic drive through the whole tree" energy 🌳✨

🎀 NAME 🎀

kho_radix_walk_tree — literally walks the radix tree and calls a callback for each key 🫶

🌸 SYNOPSIS 🌸

int kho_radix_walk_tree (struct kho_radix_tree *tree , const struct
kho_radix_walk_cb *cb , void *data );

🦋 ARGUMENTS 🦋

  • tree — a pointer to the KHO radix tree you're about to walk 💅 this is the main character, the tree in question.
  • cb — the set of callbacks that get invoked during the tree walk. yes, plural, it's a whole little squad 🎀
  • data — an opaque data pointer, passed to each callback in cb. opaque means don't peek, just pass it along 🙈

💜 DESCRIPTION 💜

so what does this actually do? it walks the radix tree, searching from the top level down to the lowest level (level 0), invoking the appropriate callbacks as it goes ✨

top-down, no cap. it hits the levels in order and lets cb handle the vibes at each stop 🧚

⭐ RETURN ⭐

  • 0 if the walk completed the specified tree 👑 (a full, clean run, slay)
  • or the non-zero return value from the callback that stopped the walk 💀 yep — a callback can call it and end the whole thing, and you get its value back.
