470 * server_io: server's SSL communication
472 * server: pseudo-I/O for SSL library
474 * s_ssl_bio: SSL filter BIO
476 * The client and the server each employ a "BIO pair":
477 * client + client_io, server + server_io.
478 * BIO pairs are symmetric. A BIO pair behaves similar
479 * to a non-blocking socketpair (but both endpoints must
480 * be handled by the same thread).
481 * [Here we could connect client and server to the ends
482 * of a single BIO pair, but then this code would be less
483 * suitable as an example for BIO pairs in general.]
485 * Useful functions for querying the state of BIO pair endpoints:
487 * BIO_ctrl_pending(bio) number of bytes we can read now
488 * BIO_ctrl_get_read_request(bio) number of bytes needed to fulfil
489 * other side's read attempt
490 * BIO_ctrl_get_write_gurantee(bio) number of bytes we can write now
492 * ..._read_request is never more than ..._write_guarantee;
493 * it depends on the application which one you should use.

497 * can be sure that there is *some* progress in each iteration; so
