EC_NODE_SUBSET_ADD(3)

✨ EC_NODE_SUBSET_ADD(3) ✨

okay so bestie, we're in the Libecoli Programmer's Manual, section 3, and today's main character is ec_node_subset_add 💅 buckle up

---

🌸 NAME 🌸

ec_node_subset_add — Add a child to a subset node. that's it, that's the whole vibe 🫶

---

🎀 SYNOPSIS 🎀

first things first, you gotta invite the header in:

#include <ecoli/node_subset.h>

and then here's the function, looking all cute and official:

int ec_node_subset_add(
    struct ec_node   *node,   /* The subset node. */
    /*
     * The child node to add. It is consumed and will be freed when the parent
     * is freed, or immediately on error.
     */
    struct ec_node   *child
);

so like, <cyan>*node is your subset node — the one you're adding to, the parent, the one holding the group chat together 👑

and <cyan>*child is the child node you're adding. important: it gets consumed. meaning it'll be freed when the parent gets freed, or like, immediately if there's an error. so don't you dare go freeing it yourself afterward, that's not your job anymore bestie, it's giving "handed off, not your problem" ✨

🔥 RETURN VALUE 🔥

• 0 on success 🎉 slay
• -1 on error, and errno is set so you can go investigate what went wrong 😭
