int ldns_dname_compare(const ldns_rdf *dname1, const ldns_rdf *dname2);

int ldns_dname_interval(const ldns_rdf *prev, const ldns_rdf *middle, const ldns_rdf *next);


ldns_dname_compare() Compares the two dname rdf's according to the algorithm for ordering in RFC4034 Section 6.
dname1: First dname rdf to compare
dname2: Second dname rdf to compare
Returns -1 if dname1 comes before dname2, 1 if dname1 comes after dname2, and 0 if they are equal.

ldns_dname_interval() check if middle lays in the interval defined by prev and next prev <= middle < next. This is useful for nsec checking
prev: the previous dname
middle: the dname to check
next: the next dname return 0 on error or unknown, -1 when middle is in the interval, +1 when not
