I need example codes for the initial handshake for C codes that use
normal I/O sockets.

I need codes for Server DNS, Server HTTPS, Server IMAP, POP3, and STMP.

I found only this:
https://www.gnutls.org/manual/html_node/GnuTLS-application-examples.html

But those examples are incomplete and don't exist for the servers that i need.
