Wait for SSL_connect() to terminate (un)successfully...
finished_connect = 0;
while (!finished_connect) {
ret=SSL_connect(ssl_con):
errcode=SSL_get_error(ssl_con, ret);
switch (errcode) {
case SSL_ERROR_NONE:
finished_connect = 1; /* Hurray, connection established */
break;
case SSL_ERROR_WANT_READ:
case SSL_ERROR_WANT_WRITE:
perform select() like functions and wait for bytes to be sent or received;
break;
case SSL_ERROR_ZERO_RETURN:
finished_connect = 1; /* The peer closed cleanly, no connection */
break;
default:
finished_connect = 1; /* Fatal error */
break;
}
}
if (errocode == SSL_ERROR_NONE)
connection_established();
else
handle_connection_failure();
Best,
Lutz
