-The write operation was not successful, because the write side of the
-SSL connection was shut down (the SSL_SENT_SHUTDOWN flag in the shutdown
-state is set) by calling L<SSL_shutdown(3)|SSL_shutdown(3)> or
-L<SSL_set_shutdown(3)|SSL_set_shutdown(3)>. It is also possible, that the
-underlying connection was closed.
-Call SSL_get_error() with the return value B<ret> to find out,
-whether an error occurred or the connection was shut down cleanly
-(SSL_ERROR_ZERO_RETURN).
