xbc_find_value(9)

💖 NAME 💖

hiii bestie, welcome to xbc_find_value(9) from the Kernel API Manual — today we're finding values in the XBC tree and it's giving main-character energy 💅✨

xbc_find_value — Find a value which matches the key. No cap, that's the whole assignment. 🎀

✨ SYNOPSIS ✨

const char * xbc_find_value (const char *key , struct xbc_node **vnode
       );

🎀 ARGUMENTS 🎀

• key — Search key. This is the key you're matching against, bestie. 🔑
• vnode — A container pointer of XBC value node. The found value node gets stored in *vnode. 🫶

💖 DESCRIPTION 💖

Okay so picture the whole of XBC tree, right? This searches a value whose key matches key from whole of XBC tree and returns the value if found. The found value node is stored in *vnode. Simple, iconic, slay. 🌸

ngl, there's a little plot twist: Note that this can return 0-length string and store NULL in *vnode for key-only (non-value) entry. It's not a bug, it's just the vibe for that case. 🫠💀
