2269 * client_io: client's SSL communication; usually to be
2270 * relayed over some I/O facility, but in this
2271 * test program, we're the server, too:
2273 * server_io: server's SSL communication
2275 * server: pseudo-I/O for SSL library
2277 * s_ssl_bio: SSL filter BIO
2279 * The client and the server each employ a "BIO pair":
2280 * client + client_io, server + server_io.
2281 * BIO pairs are symmetric. A BIO pair behaves similar
2282 * to a non-blocking socketpair (but both endpoints must
2283 * be handled by the same thread).
2284 * [Here we could connect client and server to the ends
2285 * of a single BIO pair, but then this code would be less
2286 * suitable as an example for BIO pairs in general.]
2288 * Useful functions for querying the state of BIO pair endpoints:
2290 * BIO_ctrl_pending(bio) number of bytes we can read now
2291 * BIO_ctrl_get_read_request(bio) number of bytes needed to fulfil
2292 * other side's read attempt
2293 * BIO_ctrl_get_write_guarantee(bio) number of bytes we can write now
2295 * ..._read_request is never more than ..._write_guarantee;
2296 * it depends on the application which one you should use.
2300 * We have non-blocking behaviour throughout this test program, but
2301 * can be sure that there is *some* progress in each iteration; so we
2302 * don't have to worry about ..._SHOULD_READ or ..._SHOULD_WRITE --
