NAME
       ldns_dname_compare, ldns_dname_interval - compare two dnames

SYNOPSIS
       #include	<stdint.h>
       #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.
	      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 mid-
	      dle is in	the interval, +1 when not
