dtikhonov / lsquic-tutorial Goto Github PK

I have two concerns about this lsquic's tutorial (https://github.com/dtikhonov/lsquic-tutorial/blob/master/tut.c).
Concern 1 :
You said that server reads a string from client, reverse it and sends it back to client.
I tried to see where the string is given in the code but I didn't see.
Can you show me how and where can I get the value of spec[n].iov in order to see the value of the
string sent between client and server, please?

Concern 2 :
How can I do to maintain the connexion between client and server and send the string many times?

Apologize me for many questions, I'm new on lsquic and also on socket programming.

Your help will be appreciated.

Regards

Hello， Is it possible that openssl is a version dependent issue？
