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);


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

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

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). .br rdf: the rdf to look in .br labelpos: return the label with this number .br Returns a ldns_rdf* with the label as name or NULL on error
