If there's an +unfinished line, s6-tai64n processes it, adds a newline character to it, +and writes it before exiting. </li> +</ul> + +<h2> Notes </h2> + +<p> + s6-tai64n does neither "line buffering" nor "block buffering". It does +<em>optimal buffering</em>, i.e. it flushes its output buffer every time +it risks blocking on input. Every filter should behave this way, whether +its output is a tty or not: it's simpler and more efficient in every +case. +</p> + +</body> +</html> |
