ldns_dname_is_subdomain()  test  whether the name sub falls under parent (i.e. is a subdomain of parent).
              This function will return false if the given dnames are equal.
              sub: the name to test
              parent: the parent's name
              Returns true if sub falls under parent, otherwise false

       ldns_dname_str_absolute() Checks whether the given dname string is absolute (i.e. ends with a '.')
              *dname_str: a string representing the dname
              Returns true or false

       ldns_dname_label() look inside the rdf and if it is an LDNS_RDF_TYPE_DNAME try and  retrieve  a  specific
              label. The labels are numbered starting from 0 (left most).
              rdf: the rdf to look in
              labelpos: return the label with this number
              Returns a ldns_rdf* with the label as name or NULL on error
