Hi Ye,
I have yet another question on TCP_IP4_PROTOCOL handle I got from
NetLibCreateServiceChild().
I wanted to use this TCP4 handle for SSL communication. To create SSL
connection, ssl_set_fd() needs socket FD. My question is how to get
underlying socket fd from TCP4 handle? I don't see socket fd details in
TCP4 structure. If it is not possible from TCP_IP4_PROTOCOL then do I need
to create TCP socket separately to make a SSL connection?
Thanks,
Ritesh
