* [Here we could connect client and server to the ends
* of a single BIO pair, but then this code would be less
* suitable as an example for BIO pairs in general.]
*
* Useful functions for querying the state of BIO pair endpoints:
*
* BIO_ctrl_pending(bio) number of bytes we can read now
* BIO_ctrl_get_read_request(bio) number of bytes needed to fulfill
* other side's read attempt
* BIO_ctrl_get_write_guarantee(bio) number of bytes we can write now

* ..._read_request is never more than ..._write_guarantee;
* it depends on the application which one you should use.
