eeh_pe_next(9)

💖 eeh_pe_next 💖

okay so this is a page from the Kernel API Manual (yes, the kernel has lore too, and this is part of it 🫶) — and bestie, it's a short one, so let's get into it.

---

✨ NAME ✨

eeh_pe_next — retrieve the next PE in the tree 🌳

like, it walks the tree and hands you the next PE. that's the whole vibe check.

---

🌸 SYNOPSIS 🌸

struct eeh_pe * eeh_pe_next (struct eeh_pe *pe , struct eeh_pe *root );

look at that signature. it's giving "give me a pointer, get a pointer". iconic honestly.

---

🎀 ARGUMENTS 🎀

• pe — current PE. as in, the one you're standing on right now, bestie. where you're at.
• root — root PE. the top of the tree, the main character of the hierarchy, the one everything else hangs off of 👑

---

💅 DESCRIPTION 💅

so what does it do? the function is used to retrieve the next PE in the hierarchy PE tree. that's it. that's the whole thing. you give it your current spot (pe) and the root of the tree (root), and it gets you the next PE in the hierarchy PE tree.

no cap, that's the entire description. sometimes the kernel is just chill like that 🦋
