Perform a SSL handshake on a stream.
socket-stream-handshake stream &optional timeout => success
socket-stream-handshake performs a handshake on stream, which must be attached to SSL.
socket-stream-handshake returns false if the handshake does not finish in timeout seconds or if the SSL connection was cleanly closed by the other side. Other failures cause an error to be signaled.
socket-stream-handshake returns true on success.
The other socket-stream interface functions signal errors if the handshake fail for any reason, including timeout or clean close.
If SSL was attached with ssl-side
:both, then you will need to specify which side to take in the handshake by calling
ssl-set-connect-state with the ssl-pointer return by socket-stream-ssl.
