         * SSL_ERROR_NONE corresponds with retval > 0. With SSL_(read, write)
         * this is the number of plaintext bytes sent or received. With

         * (retval = -1, errno = ETIMEDOUT) when the time limit is exceeded.
         *
         * All other SSL_ERROR_* cases correspond with retval <= 0. With
         * SSL_(read, write, accept, connect) retval == 0 means that the
         * remote party either closed the network connection or that it
         * requested TLS shutdown; with SSL_shutdown() retval == 0 means that
         * our own shutdown request is in progress. With all operations
         * retval < 0 means that there was an error. In the latter case,
         * SSL_ERROR_SYSCALL means that error details are returned via the
         * errno value.

         * network I/O.

         * isn't really complete when the call returns. We could hide that
