creates a new dname rdf from a string.
Definition: dname.c:265
ldns_dname_absolute
signed char ldns_dname_absolute(const ldns_rdf *dname)
Checks whether the given dname is absolute (i.e.
Definition: dname.c:544
ldns_dname_reverse
ldns_rdf * ldns_dname_reverse(const ldns_rdf *d)
Returns a clone of the given dname with the labels reversed.
