ldns_dnssec_data_chain_new() Creates a new dnssec_chain structure
Returns ldns_dnssec_data_chain *

ldns_dnssec_data_chain_free() Frees a dnssec_data_chain structure

*chain: The chain to free

ldns_dnssec_data_chain_deep_free() Frees a dnssec_data_chain structure, and all data contained therein

*chain: The dnssec_data_chain to free

ldns_dnssec_build_data_chain() Build an ldns_dnssec_data_chain, which contains all DNSSEC data that is needed to derive the trust tree later

The data_set will be cloned

*res: resolver structure for further needed queries
qflags: resolution flags
*data_set: The original rrset where the chain ends
*pkt: optional, can contain the original packet (and hence the sigs and maybe the key)
*orig_rr: The original Resource Record

Returns the DNSSEC data chain

ldns_dnssec_data_chain_print() Prints the dnssec_data_chain to the given file stream

*out: The file stream to print to
*chain: The dnssec_data_chain to print
