.SH NAME
named-wireformat \- parse DNS wire format messages
.SH SYNOPSIS
.sp
\fBnamed\-wireformat\fP [\fB\-b\fP] [\fB\-d\fP] [\fB\-h\fP] [\fB\-m\fP flag] [\fB\-p\fP] [\fB\-r\fP] [\fB\-s\fP] [\fB\-t\fP] [{filename}]
.SH DESCRIPTION
.sp
\fBnamed\-wireformat\fP reads a DNS message in wire format, either
in hexidecimal form or as raw data, from a file or from standard input,
and translates it to text format to check whether it is formatted correctly.
.SH OPTIONS
.INDENT 0.0
.TP
.B \-b
Use best\-effort parsing. Errors in message content will be
ignored, so long as the message itself can still be parsed as valid
DNS wire data.
.UNINDENT
.INDENT 0.0
.TP
.B \-d
Read input as raw binary data instead of hexidecimal text.
.UNINDENT
.INDENT 0.0
.TP
.B \-h
Print out the help menu.
.UNINDENT
.INDENT 0.0
.TP
.B \-m flag
Turn on memory debugging flags. Possible flags are \fBusage\fP,
\fBtrace\fP and \fBrecord\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B \-p
Preserve the order of records in the message, instead of sorting
by name and type.
.UNINDENT
.INDENT 0.0
.TP
.B \-r
After parsing and displaying the input message, render it back to wire
format, parse that, and display it again. This is used to confirm
that parsing and rendering are idempotent.
.UNINDENT
.INDENT 0.0
.TP
.B \-s
Print memory statistics on shutdown.
.UNINDENT
.INDENT 0.0
.TP
.B \-t
Parse the input as a TCP DNS message, with a two\-byte length header.
.UNINDENT
.SH ARGUMENTS
.INDENT 0.0
.TP
.B filename
If specified, the message to be parsed is read from this file.
Otherwise, it is read from the standard input.
