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
