436 | * client_io: client's SSL communication; usually to be | |

447 | * client + client_io, server + server_io. | |
448 | * BIO pairs are symmetric. A BIO pair behaves similar | |
449 | * to a non-blocking socketpair (but both endpoints must | |
450 | * be handled by the same thread). | |
451 | * | |
452 | * Useful functions for querying the state of BIO pair endpoints: | |
453 | * | |
454 | * BIO_ctrl_pending(bio) number of bytes we can read now | |
455 | * BIO_ctrl_get_read_request(bio) number of bytes needed to fulfil | |
456 | * other side's read attempt | |
457 | * BIO_ctrl_get_write_gurantee(bio) number of bytes we can write now | |
458 | * | |
459 | * ..._read_request is never more than ..._write_guarantee; | |
460 | * it depends on the application which one you should use. | |
