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 .PP .SH AUTHOR The ldns team at NLnet Labs. .SH REPORTING BUGS Please report bugs to dns-team@nlnetlabs.nl or on GitHub at https://github.com/NLnetLabs/ldns/issues .SH COPYRIGHT Copyright (c) 2004 - 2006 NLnet Labs. .PP Licensed under the BSD License.
