EC_NODE_EXPR(3)

💖 EC_NODE_EXPR 💖

okay bestie, so you know ec_node_expr(3)? that's from the Libecoli Programmer's Manual and it's literally the cutest little constructor for an expression node 🌸 this is your girl's guide, no cap.

---

✨ NAME ✨

ec_node_expr — Create an expression node. that's it. that's the whole job. she makes a node, she slays 💅

---

🦋 SYNOPSIS 🦋

#include <ecoli/node_expr.h>

struct ec_node * ec_node_expr(
    const char   *id   /* The node identifier. */
);

so you pull in the header, then you hand her one little id — that's the node identifier — and boom, node time 🎀

---

👑 RETURN VALUE 👑

she gives you back the node, or NULL on error — and when that happens, bestie, errno is set, so go check it, don't just sit there 😭

fr fr: NULL means something went wrong. errno is your bestie here. look it up.
