ldns_dname_is_subdomain, ldns_dname_str_absolute, ldns_dname_label - check properties of dnames

SYNOPSIS

#include <stdint.h> #include <stdbool.h> #include <ldns/ldns.h> 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);

DESCRIPTION

ldns_dname_is_subdomain() 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. 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
