[noPoll] nopoll_conn_set_on_ready don't work as expected

[Elmar Sieke]

Hello Francis,
according to your answer I have still one question. The debug output
shows that the connection handshake was done without error. In this
case the equivalent listener function fired on_ready. The client
function doesn't.
nopoll_conn.c:nopoll_conn_complete_handshake_check_listener()nopoll_con
n_complete_handshake_check_client()
Is this behavior desired? Or should the client function also fired
on_ready?
debug output:(proc 22914): (debug)nopoll_conn.c:2655 Sec-Websocket-
Accept matches expected
value..nopoll_conn_complete_handshake_check_client (0x1d71420,
0x1d72380)=1
Thank you so muchElmar
