DESCRIPTION

21       ldns_dname_compare() Compares the two  dname  rdf's  according  to  the
22              algorithm for ordering in RFC4034 Section 6.
23              dname1: First dname rdf to compare
24              dname2: Second dname rdf to compare
25              Returns  -1  if  dname1  comes  before dname2, 1 if dname1 comes
26              after dname2, and 0 if they are equal.
27
28       ldns_dname_interval() check if middle lays in the interval  defined  by
29              prev  and  next  prev <= middle < next. This is usefull for nsec
30              checking
31              prev: the previous dname
32              middle: the dname to check
33              next: the next dname return 0 on error or unknown, -1 when  mid‐
34              dle is in the interval, +1 when not
