🦋 Kernel API Manual energy: xbc_root_node(9) 🦋

🌸 NAME 🌸

Okay so this page is xbc_root_node(9) from the Kernel API Manual, and the name is literally xbc_root_node — Get the root node of extended boot config. Iconic behavior, no notes. 👑

✨ SYNOPSIS ✨

The whole synopsis, bestie, exactly like this:

struct xbc_node * xbc_root_node (void );

🎀 ARGUMENTS 🎀

• void — no arguments. Not one. It's giving zero-argument main character energy. 💅

💖 DESCRIPTION 💖

So this function returns the address of the root node of extended boot config. If the extended boot config isn't initialized yet, it returns NULL — that's the whole story, fr fr. No cap. ✨
