CURLOPT_DNS_LOCAL_IP6(3) curl_easy_setopt options 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.
