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). The application does not have to keep the string around after setting this option. .SH DEFAULT NULL .SH PROTOCOLS All .SH EXAMPLE TODO .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. .SH "SEE ALSO" .BR CURLOPT_DNS_INTERFACE "(3), " CURLOPT_DNS_LOCAL_IP4 "(3), "
