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_ttree 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
