.SH DESCRIPTION
|
|
|
|
|
dns_txt looks up TXT records for the fully-qualified domain name in
|
|
|
|
|
\fIfqdn\fR. It puts the concatenation of the TXT records into \fIout\fR
|
|
|
|
|
and returns 0. If the domain does not exist in DNS, or has no TXT
|
|
|
|
|
records, \fIout\fR will be empty.
|
|
|
|
|
|
|
|
|
|
If dns_txt has trouble with the DNS lookup or runs out of memory, it returns
|
|
|
|
|
-1, setting errno appropriately. It may or may not change \fIout\fR.
