[libmicrohttpd] About an HTTPS connection Upgraded

[Nicolas Mora]

Hello,

I'm still working on a websocket implementation based on MHD, the non 
secure websocket works fine, but the secure websocket doesn't work yet.

I'm having problems with the socket and the tls session. I get my 
inspiration from the test_upgrade.c file but I can't have a valid tls 
session anyway.

Inside the upgrade callback function, I use the same sequence as in the 
example program to initiate the tls session and the result tells me it's 
connected:
https://github.com/babelouest/ulfius/blob/2.0/src/u_websocket.c#L127

But when it comes to reading or sending data, I got nothing or errors, 
whether the socket is in blocking mode or not.

The read/write functions are at the end of the file:
https://github.com/babelouest/ulfius/blob/2.0/src/u_websocket.c#L720

Does anyone see what's wrong with my code?

Thanks in advance
