bool ldns_dname_is_subdomain(const ldns_rdf *sub, const ldns_rdf *parent);

bool ldns_dname_str_absolute(const char *dname_str);

ldns_rdf * ldns_dname_label(const ldns_rdf *rdf, uint8_t labelpos);

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
