get_tree_page_by_index(9)

💖 NAME 💖

Hey bestie! You're on the page for get_tree_page_by_index(9) from the Kernel API Manual, and this little icon is here to get the tree page for a given height and page index. That's the whole vibe, no cap. 🦋

✨ SYNOPSIS ✨

struct tree_page * get_tree_page_by_index (struct forest *forest ,
root_count_t root_index , height_t height , page_number_t page_index );

🌸 ARGUMENTS 🌸

• forest — the block map forest. Like, the whole forest, not just one tree. 🌳
• root_index — the root index of the tree to search. You're telling it which root to check, bestie. 👑
• height — the height in the tree. Yes, actual height. Not a personality trait. 💅
• page_index — the page index. That's the page coordinate, periodt. 🎀

🫶 RETURN 🫶

The requested page. That's it — you ask, it returns the requested page, and we love a straightforward queen. ✨
