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

.SH DESCRIPTION
.HP
\fIldns_dname_compare\fR()
Compares the two dname rdf's according to the algorithm for ordering
in RFC4034 Section 6.
\.br
\fBdname1\fR: First dname rdf to compare
\.br
\fBdname2\fR: 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.
.PP
.HP
\fIldns_dname_interval\fR()
check if middle lays in the interval defined by prev and next
prev <= middle < next. This is useful for nsec checking
\.br
\fBprev\fR: the previous dname
\.br
\fBmiddle\fR: the dname to check
\.br
\fBnext\fR: the next dname
return 0 on error or unknown, -1 when middle is in the interval, +1 when not
