DESCRIPTION

       ldns_dnssec_trust_tree_new() Creates a new (empty) dnssec_trust_tree structure

              Returns ldns_dnssec_trust_tree *

       ldns_dnssec_trust_tree_free() Frees the dnssec_trust_tree recursively

              There is no deep free; all data in the trust tree consists of pointers to a
              data_chain

              tree: The tree to free

       ldns_dnssec_trust_tree_depth() returns the depth of the trust tree

              tree: tree to calculate the depth of
              Returns The depth of the tree

       ldns_dnssec_derive_trust_tree() Generates a dnssec_trust_tree for the given rr from the
              given data_chain

              This does not clone the actual data; Don't free the data_chain before you are done
              with this tree

              *data_chain: The chain to derive the trust tree from
              *rr: The RR this tree will be about
              Returns ldns_dnssec_trust_tree *

       ldns_dnssec_trust_tree_contains_keys() Returns OK if there is a trusted path in the tree
              to one of the DNSKEY or DS RRs in the given list

              \param *tree The trust tree so search \param *keys A ldns_rr_list of DNSKEY and DS
              rrs to look for

              Returns LDNS_STATUS_OK if there is a trusted path to one of the keys, or the
              *first* error encountered if there were no paths

       ldns_dnssec_trust_tree_print() Prints the dnssec_trust_tree structure to the given file
              stream.

              If a link status is not LDNS_STATUS_OK; the status and relevant signatures are
              printed too

              *out: The file stream to print to
              tree: The trust tree to print
              tabs: Prepend each line with tabs*2 spaces
              extended: If true, add little explanation lines to the output

       ldns_dnssec_trust_tree_print_sm()

       ldns_dnssec_trust_tree_add_parent() Adds a trust tree as a parent for the given trust tree

              *tree: The tree to add the parent to
              *parent: The parent tree to add
              *parent_signature: The RRSIG relevant to this parent/child connection
              parent_status: The DNSSEC status for this parent, child and RRSIG
              Returns LDNS_STATUS_OK if the addition succeeds, error otherwise

       ldns_dnssec_derive_trust_tree_normal_rrset() Sub function for derive_trust_tree that is
              used for a 'normal' rrset

              new_tree: The trust tree that we are building
              data_chain: The data chain containing the data for the trust tree
              cur_sig_rr: The currently relevant signature

       ldns_dnssec_derive_trust_tree_dnskey_rrset() Sub function for derive_trust_tree that is
              used for DNSKEY rrsets

              new_tree: The trust tree that we are building
              data_chain: The data chain containing the data for the trust tree
              cur_rr: The currently relevant DNSKEY RR
              cur_sig_rr: The currently relevant signature

       ldns_dnssec_derive_trust_tree_ds_rrset() Sub function for derive_trust_tree that is used
              for DS rrsets

              new_tree: The trust tree that we are building
              data_chain: The data chain containing the data for the trust tree
              cur_rr: The currently relevant DS RR

       ldns_dnssec_derive_trust_tree_no_sig() Sub function for derive_trust_tree that is used
              when there are no signatures

              new_tree: The trust tree that we are building
              data_chain: The data chain containing the data for the trust tree
