bool bson_iter_recurse (const bson_iter_t *iter, bson_iter_t *child);
- iter: A bson_iter_t.
- child: A bson_iter_t.
The bson_iter_recurse() function shall initialize child using the embedded document or array currently observed by iter.
If there was a failure to initialize the iter, false is returned and both iter and child should be considered invalid.
This should only be called when observing an element of type BSON_TYPE_ARRAY or BSON_TYPE_DOCUMENT.
If iter observes an element of type BSON_TYPE_ARRAY or BSON_TYPE_DOCUMENT, then child is initialized and the function returns true. Otherwise, the function returns false and child is invalid.
