add_rr_to_tree() add_opt_rr_to_tree() proto_tree_add_item(rr_tree, hf_dns_rr_len, tvb, offset, 2, ENC_BIG_ENDIAN); dissect_dns_answer() case T_PTR: /* Domain Name Pointer (12) */ { const gchar *pname; int pname_len; used_bytes = get_dns_name(tvb, cur_offset, 0, dns_data_offset, &pname, &pname_len); https://osqa-ask.wireshark.org/questions/24732/how-to-get-data-inside-proto_tree-tree/ I understand from Graham's response above that as much as I'd like to find proto_tree_get_item, it doesn't exist. How can I get the value of hf_dns_rr_len that is set in one of the add_xxx_rr_to_tree() functions when the code is running in dissect_dns_answer()? thanks chuckc
