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
       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

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
           curl_easy_setopt(curl, CURLOPT_DNS_LOCAL_IP6, "fe80::a9ff:fe46:b619");
           res = 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.
