Hello Elmar,<br>

<blockquote type="CITE">
<pre>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);
</pre>
</blockquote>
<br>
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>
