1120 * BIO_ctrl_get_read_request(bio) number of bytes needed to fulfil
1121 * other side's read attempt
1122 * BIO_ctrl_get_write_guarantee(bio) number of bytes we can write now
1123 *
1124 * ..._read_request is never more than ..._write_guarantee;
1125 * it depends on the application which one you should use.
