.TH dns_ip4_qualify 3

|

.SH NAME
|
||
|
|
dns_ip4_qualify \- qualify name and look up IPv4 addresses
|
||
|
|
.SH SYNTAX
|
||
|
|
.B #include <dns.h>
|
||
|
|
|
||
|
|
int \fBdns_ip4_qualify\fP(stralloc* \fIout\fR,stralloc* \fIfqdn\fR,
|
||
|
|
const stralloc* \fIudn\fR);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
dns_ip4_qualify feeds the name \fIudn\fR through qualification and looks up
|
||
|
|
4-byte IP addresses for the result. It puts the fully qualified domain name
|
||
|
|
into \fIfqdn\fR, puts the concatenation of the IP addresses into \fIout\fR, and
|
||
|
|
returns 0. If the domain does not exist in DNS, or has no IP addresses,
|
||
|
|
\fIout\fR will be empty.
|
||
|
|
|
||
|
|
If dns_ip4_qualify has trouble with the qualification, has trouble with DNS, or
|
||
|
|
runs out of memory, it returns -1, setting errno appropriately. It may or may
|
||
|
|
not change \fIout\fR and \fIfqdn\fR.
