MTREE_NNODE(3)

MTREE_NNODE(3) 💅

okay bestie, welcome to the Librecast Programmer's Manual — this one lives in section 3 and it's lowkey the chillest lil function in the whole tree 🌳✨

NAME 🎀

mtree_nnode — gimme a pointer to an mtree node, bestie

LIBRARY 📚

Librecast library (liblibrecast, -llibrecast) 🦋

SYNOPSIS ✨

#include <librecast/mtree.h>

uint8_t *mtree_nnode(mtree_t *tree, size_t node);

Compile and link with -llibrecast. 🔗

DESCRIPTION 🌸

so the way that mtree_nnode works is it hands you back a pointer to the hash of node node, where 0 = root. that's it. that's the whole vibe. number zero is the root, no cap. 👑

RETURN VALUE 💖

mtree_nnode() returns a pointer to the hash of the numbered node. 🫶

but if something goes wrong, it returns NULL, and errno gets set to tell you what went wrong. so check that pointer, bestie, fr fr. 😭

ERRORS 💀

• ERANGE — the node you asked for is out of range for tree. it's giving "bestie that node does not exist". 🚫

SEE ALSO 🔥
