CURLOPT_DNS_LOCAL_IP6(3) libcurl CURLOPT_DNS_LOCAL_IP6(3)
NAME
CURLOPT_DNS_LOCAL_IP6 - IPv6 address to bind DNS resolves to
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_LOCAL_IP6, char *address);
DESCRIPTION
Set the local IPv6 address that the resolver should bind to. The argu-
ment should be of type char * and contain a single IPv6 address as a
string. Set this option to NULL to use the default setting (do not
bind to a specific IP address).
The application does not have to keep the string around after setting
this option.
DEFAULT
NULL
PROTOCOLS
All
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
curl_easy_setopt(curl, CURLOPT_DNS_LOCAL_IP6, "fe80::a9ff:fe46:b619");
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
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
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.
