problem with my code

[Attila Csosz]

Hi,

I'm trying to connect to www.google.com on 443 port with SSL but my code
shows an error at ssl_write.
This code is written in C++ Builder on Windows.
Everything is good before this point
 err = SSL_write(ssl, buf, strlen(buf));

But after that err=-1 and code=1 (means SSL_ERROR_SSL )

What may the problem?

My question also: I have found that maybe I have to use ERR_get_error but
this function is in an another dll (libeay32) how will this function
connect to the ssl instance?

Thanks for your help
