EC_NODE_EXPR_SET_VAL_NODE(3)

💖 ec_node_expr_set_val_node — Libecoli Programmer's Manual 💖

okay bestie, gather round, we're in the Libecoli Programmer's Manual and this page is literally about one tiny function with main character energy ✨

---

🎀 NAME 🎀

ec_node_expr_set_val_node — sets the value node for an expression, and the value node is the terminal one, no cap 🌸

---

✨ SYNOPSIS ✨

#include <ecoli/node_expr.h>

int ec_node_expr_set_val_node(
    struct ec_node   *gen_node,  /* The expression node. */
    /*
     * The node matching values. It is consumed and will be freed when the
     * parent is freed, or immediately on error.
     */
    struct ec_node   *val_node
);

so like, you pass in gen_node — that's the expression node, the main one, the parent, the one holding the whole situation together 🫶

and then val_node is the node matching values. but here's the tea, and it's important tea: val_node gets consumed 💀 it gets freed when the parent is freed, OR immediately if there's an error. so do not go touching it afterwards, bestie, it's gone, it's giving ghost 👻

🔥 RETURN VALUE 🔥

• 0 — success, we ate, slay 💅
• -1 — error, and errno is set, so go check it 😭
