EC_NODE_EXPR_ADD_BIN_OP(3)

✨ EC_NODE_EXPR_ADD_BIN_OP(3) ✨

okay bestie, welcome to the Libecoli Programmer's Manual 🎀 this one is a lil function page from libecoli and it's genuinely so simple you're gonna eat it up 💅

---

🌸 NAME 🌸

ec_node_expr_add_bin_op — add a binary operator to an expression node 🦋

like. that's it. that's the whole job. she adds a bin op and she slays ✨

---

💖 SYNOPSIS 💖

#include <ecoli/node_expr.h>

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

so we got two args, no cap:

• gen_node — the expression node 💫 this is your main character, the thing you're decorating. the comment in the header literally says The expression node. iconic, no notes.
• op — the operator node 🔥 and listen, this is the important part: it is consumed. she's been eaten. she will be freed when the parent is freed, or immediately on error. so do NOT go touching her afterwards, bestie, that's giving use-after-free and we don't do that here 🙈

⚠️ real talk: because op gets consumed, you don't own it anymore after this call. hand her over and let go. no takebacks 💀

---

⭐ RETURN VALUE ⭐

• 0 — success, we ate, we devoured 👑
• -1 — error, and errno is set so go check it fr fr
