If there's an 36 unfinished line, s6-tai64n processes it, adds a newline character to it, 37 and writes it before exiting. </li> 38 </ul> 39 40 <h2> Notes </h2> 41 42 <p> 43 s6-tai64n does neither "line buffering" nor "block buffering". It does 44 <em>optimal buffering</em>, i.e. it flushes its output buffer every time 45 it risks blocking on input. Every filter should behave this way, whether 46 its output is a tty or not: it's simpler and more efficient in every 47 case. 48 </p> 49 50 </body> 51 </html>
