into or retrieved out of the BIO before being able to continue.
+When using a generic method (see L<SSL_CTX_new(3)|SSL_CTX_new(3)>), it

=head1 RETURN VALUES
The following return values can occur:
by the specifications of the TLS/SSL protocol. Call SSL_get_error() with the
return value B<ret> to find out the reason.

+=item E<lt>0
The TLS/SSL handshake was not successful because a fatal error occurred either
at the protocol level or a connection failure occurred. The shutdown was
