radix_tree_insert(9)

📦 version 7.3.1, in nixpkgs unstable

💖 radix_tree_insert — a.k.a. the "put my stuff in the tree" moment ✨

okay so real talk, this is a page from the Kernel API Manual, section 9 — the kernel devs' very own corner of the manpage universe 🧚. Buckle up bestie, it's short and sweet.

🌸 SYNOPSIS 🌸

int radix_tree_insert (struct radix_tree_root *root , unsigned long
index , void *item );

that's it. that's the whole vibe. three args, returns an int, lowercase int not INT because the kernel is dramatic like that 💅.

🎀 ARGUMENTS 🎀

  • root — the radix tree root 🫶. this is literally the tree itself, the main character. you're handing it your stuff so it can hold onto it for you.
  • index — the index key 🔑. this is where in the tree your item lands — the position label, iykyk.
  • item — the item to insert 📦. your precious little pointer, going into the tree at that index. slay.

🦋 DESCRIPTION 🦋

Insert an item into the radix tree at position index. 🌈

lowkey that's the entire description ngl. put the thing in the tree at the spot. that's the whole bit. no cap. 💀✨
