In addition to B<ssl> and B<ret>, SSL_get_error() inspects the
current thread's OpenSSL error queue. Thus, SSL_get_error() must be
used in the same thread that performed the SSL I/O operation, and no

+other OpenSSL function calls should appear in between. The current
thread's error queue must be empty before the SSL I/O operation is
attempted, or SSL_get_error() will not work reliably.

about the error: If B<ret == 0>, an EOF was observed that violates
the protocol. If B<ret == -1>, the underlying B<BIO> reported an
