I think I misread some parts of specification. Thank you very much.

G'day!
Gemini, while simple, isn't quite that simple. All protocol commands and
responses are over TLS connections, so doing a send/recv on a raw
network socket will not work!
I'm not 100% sure on the best or simplest way to get a TLS stack going
in C, I've done some bits with OpenSSL, but it was not simple!
Cheers

Hello,
I've started writing a client for Gemini protocol, but since I've never been writing networking programs, I find myself at the dead end at the moment. Please could someone help me? When I send a request and get a response, the only thing I have in response is "gemini://" and nothing else. The code is given below:
