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 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  (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.
