#include <
stdbool.h>
#include <ldns/ldns.h>
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);
DESCRIPTION
-
ldns_dname_compare()
- Compares the two dname rdf's according to the algorithm for ordering
in RFC4034 Section 6.
.br
dname1: First dname rdf to compare
.br
dname2: Second dname rdf to compare
.br
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
.br
prev: the previous dname
.br
middle: the dname to check
.br
next: the next dname
return 0 on error or unknown, -1 when middle is in the interval, +1 when not
