Hi Daniel,
Thanks a lot for you kind info.
I found two ares call back function to set the socket option.
*ares_set_socket_configure_callback* and
*ares_set_socket_callback *
https://c-ares.haxx.se/ares_set_socket_configure_callback.html
https://c-ares.haxx.se/ares_set_socket_callback.html
Which function we can use to set the socket option? Both the call back
function is being introduced in two different ares release, so we need to
use the ares release according to the call back function we will use in our
program.
Regards,
Munna Kumar
