789 * server_io: server's SSL communication
791 * server: pseudo-I/O for SSL library
793 * s_ssl_bio: SSL filter BIO
795 * The client and the server each employ a "BIO pair":
796 * client + client_io, server + server_io.
797 * BIO pairs are symmetric. A BIO pair behaves similar
798 * to a non-blocking socketpair (but both endpoints must
799 * be handled by the same thread).
800 * [Here we could connect client and server to the ends
801 * of a single BIO pair, but then this code would be less
802 * suitable as an example for BIO pairs in general.]
804 * Useful functions for querying the state of BIO pair endpoints:
806 * BIO_ctrl_pending(bio) number of bytes we can read now
807 * BIO_ctrl_get_read_request(bio) number of bytes needed to fulfil
808 * other side's read attempt
809 * BIO_ctrl_get_write_guarantee(bio) number of bytes we can write now
811 * ..._read_request is never more than ..._write_guarantee;
812 * it depends on the application which one you should use.
815 /* We have non-blocking behaviour throughout this test program, but
816 * can be sure that there is *some* progress in each iteration; so
817 * we don't have to worry about ..._SHOULD_READ or ..._SHOULD_WRITE
