EC_NODE_OPTION(3)

💖 EC_NODE_OPTION(3) 💖

okay bestie, welcome to the Libecoli Programmer's Manual — this is the page for ec_node_option(3) and it's literally about making things optional. main character energy fr fr ✨

---

🌸 NAME 🌸

ec_node_option — makes a node that treats its child like it's optional 👑 like yes queen, you can show up, but also? no pressure 🫶

---

✨ SYNOPSIS ✨

#include <ecoli/node_option.h>

struct ec_node * ec_node_option(
    const char       *id,    /* The node identifier. */
    /*
     * The child node. It is consumed and will be freed when the parent is
     * freed, or immediately on error.
     */
    struct ec_node   *node
);

so we got two args, no cap:

• id — this is The node identifier. that's her name tag, her little ID, we love that for her 💅
• node — The child node. and listen, she gets consumed. like, fully. she will be freed when the parent is freed, OR immediately on error 😭 the way that she does not survive on her own. she's attached to the parent's whole vibe, iykyk.

---

🦋 RETURN VALUE 🦋

you get the node back, or NULL on error — and if it errors, errno is set. so check that errno, bestie, don't just ignore her 💀
