SYNOPSIS

*ifname);
DESCRIPTION

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.
