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
