dns_txt(3)dns_txt(3)NAME
dns_txt - look up TXT records
SYNTAX
#include <dns.h>
int dns_txt(stralloc* out,stralloc* fqdn);
DESCRIPTION
dns_txt looks up TXT records for the fully-qualified domain name in
fqdn. It puts the concatenation of the TXT records into out and returns
0. If the domain does not exist in DNS, or has no TXT records, out
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 out.
