For example, consider a trie with\nmax_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ...\n0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with\n.prefixlen = 8 make 9 nodes be written on the node stack with size 8."

Por ejemplo, considere un trie con max_prefixlen es 8, y los nodos con clave 0x00/0, 0x00/1, 0x00/2, ... 0x00/8 insertados. Las llamadas posteriores a trie_get_next_key con _key con .prefixlen = 8 hacen que se escriban 9 nodos en la pila de nodos con tama\u00f1o 8."
