AVAILABILITY
Added in 7.33.0. This option also requires that libcurl was built with a
resolver backend that supports this operation. The c-ares backend is the only
such one.
RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not,
or CURLE_NOT_BUILT_IN if support was disabled at compile-time.
