💖 ec_node_get_child — bestie's guide to snatching the n-th child 💖

okay so this is from the Libecoli Programmer's Manual (that's the <ecoli/node.h> crew, EC_NODE_GET_CHILD(3) for the searchable girlies) and it does exactly one thing but it does it flawlessly: it gets you the n-th child of a node. that's it. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

first, the include, no skipping:

#include <ecoli/node.h>

then the function itself, exactly as written, comments and all, because I love you and I want you to have the full picture:

int ec_node_get_child(
    const struct ec_node   *node,   /* The grammar node. */
    /*
     * The index of the child node, that must be lower than the number of
     * children.
     */
    size_t                  i,
    /*
     * The pointer where the child node pointer will be stored on success.
     */
    struct ec_node        **child
);

so like. you hand it a node, you hand it an index, you hand it a place to put the answer. the index? it MUST be lower than the number of children, okay? that's not a suggestion bestie, that's the rule. 🙈

🫶 RETURN VALUE 🫶

  • 0 on success — slay, you got your child 💅
  • -1 on error — not slay, something went sideways 😭

periodt.
