.SH NOTE
Since c-ares 1.6.0 the ares_options struct has been "locked" meaning that it
won't be extended to cover new funtions. This function will remain
won't be extended to cover new functions. This function will remain
functioning, but it can only return config data that can be represented in
this config struct, which may no longer be the complete set of config
options. \fBares_dup(3)\fP will not have that restriction.
The ares_options struct can not handle potential IPv6 name servers the
ares_channel might be configured to use. Function \fBares_save_options(3)\fP
will only return IPv4 servers if any. In order to retrieve all name servers
an ares_channel might be using, function \fBares_get_servers(3)\fP must be
used instead.
