2194 * server: pseudo-I/O for SSL library
2195 *
2196 * s_ssl_bio: SSL filter BIO
2197 *
2198 * The client and the server each employ a "BIO pair":
2199 * client + client_io, server + server_io.
2200 * BIO pairs are symmetric. A BIO pair behaves similar
2201 * to a non-blocking socketpair (but both endpoints must
2202 * be handled by the same thread).
2203 * [Here we could connect client and server to the ends
2204 * of a single BIO pair, but then this code would be less
2205 * suitable as an example for BIO pairs in general.]
2206 *
2207 * Useful functions for querying the state of BIO pair endpoints:
2208 *
2209 * BIO_ctrl_pending(bio) number of bytes we can read now
44e69951 2210 * BIO_ctrl_get_read_request(bio) number of bytes needed to fulfill
35a1cc90
MC		 2211 * other side's read attempt
2212 * BIO_ctrl_get_write_guarantee(bio) number of bytes we can write now
2213 *
2214 * ..._read_request is never more than ..._write_guarantee;
2215 * it depends on the application which one you should use.
