Hello Elmar,<BR>
<BR>
Certainly you have found a bug. I've updated noPoll's source code to<BR>
allow defining on_ready handlers at client side...which will be called<BR>
once handshake is completed.<BR>
<BR>
<A HREF="https://github.com/ASPLes/nopoll/commit/f1d3f5151c176f0f6af80cf671cbf611c2605d4c">https://github.com/ASPLes/nopoll/commit/f1d3f5151c176f0f6af80cf671cbf611c2605d4c</A><BR>
<BR>
We should be close to release next stable release (I hope this week),<BR>
Best Regards,<BR>

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_conn_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 much
Elmar

I have just started to use nopoll as client application. I run the
basic WebSocket client example successfully.
I tried to use nopoll_conn_set_on_ready() instead of
nopoll_conn_wait_until_connection_ready(). But my on_ready call back
never appears. Did I misunderstand something? Here is my code:
#include <stdio.h>
#include <nopoll.h>
nopoll_bool on_ready(noPollCtx *ctx, noPollConn *conn, noPollPtr
user_data){
// send a message
printf("I'm ready!\n");
return nopoll_true;
}
int
main (int argc,
char *argv[])
{
noPollCtx * ctx = nopoll_ctx_new ();
if (! ctx) {
// error some handling code here
}
nopoll_log_enable(ctx, nopoll_true);
// call to create a connection
noPollConn * conn = nopoll_conn_new (ctx, "localhost", "8080", NULL,
NULL, NULL, NULL);
if (! nopoll_conn_is_ok (conn)) {
// some error handling here
}
// set ready handle
nopoll_conn_set_on_ready (conn, on_ready, NULL);

Ok, on_ready function is not fired until it is not fully established the connection.<BR>
You'll have to send something or force negotiation with something like<BR>
this:<BR>
<BR>
// block during 5 seconds until connection is ready or timeout is reached<BR>
nopoll_conn_wait_until_connection_ready (conn, 5);<BR>
<BR>
See relevant information at nopoll_conn_new explaining more details about<BR>
your question:<BR>

// now call to wait for the loop to notify events
nopoll_loop_wait (ctx, 0);
}
