Sorry, let me clarify it, it is in client side I want to bind a client
local IP address either WiFi or other network interface.

Did you refer to use
boost::asio::ip::tcp::endpoint(boost::asio::ip::address::from_string(wifi_ip_address),
portNumber)?

I think you were talking about server side of default 0.0.0.0, it was
my fault not being clear. Anyway, can it be done to bind client side
interface IP address such as WiFi IP address? Is it possible to
specify local IP address in  boost::asio::ip::tcp::resolver::query
query(remoteServerIpAddress, portNumber) ?

Thank you Vinnie,

Kind Regards,
