.SH NAME

CURLOPT_DNS_LOCAL_IP6 \- IPv6 address to bind DNS resolves to
|
2014-06-20 06:58:18 +08:00
|
|
|
.SH SYNOPSIS
|
|
|
|
|
#include <curl/curl.h>
|
|
|
|
|
|
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_LOCAL_IP6, char *address);
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
Set the local IPv6 \fIaddress\fP that the resolver should bind to. The
|
|
|
|
|
argument should be of type char * and contain a single IPv6 address as a
|
|
|
|
|
string. Set this option to NULL to use the default setting (don't bind to a
|
|
|
|
|
specific IP address).
|
2016-12-21 21:48:35 +08:00
|
|
|
|
|
|
|
|
The application does not have to keep the string around after setting this
|
|
|
|
|
option.

.SH AVAILABILITY
|
|
|
|
|
This option requires that libcurl was built with a resolver backend that
|
|
|
|
|
supports this operation. The c-ares backend is the only such one.
|
|
|
|
|
|
|
|
|
|
Added in 7.33.0
|
|
|
|
|
.SH RETURN VALUE

|
|
|
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not,
|
|
|
|
|
CURLE_NOT_BUILT_IN if support was disabled at compile-time, or
|
|
|
|
|
CURLE_BAD_FUNCTION_ARGUMENT when given a bad address.
