This generator is used to create a random sequence of bytes when reading from the channel. It is not possible to seek the channel. </dl> <a name="options"><h2>OPTIONS</h2> Memory channels created by <b class='cmd'>random</b> provide one additional option to set or query. <dl> <dt><i class='arg'>-delay ?milliseconds?</i><dd> A <b class='cmd'>random</b> channel is always writable and readable. This means that all <b class='cmd'>fileevent</b>-handlers will fire continuously. To avoid starvation of other event sources the events raised by this channel type have a configurable delay. This option is set in milliseconds and defaults to 5. </dl> <a name="seealso"><h2>SEE ALSO</h2> memchan, fifo, fifo2, null, zero <a name="keywords"><h2>KEYWORDS</h2> random, in-memory channel, channel, i/o <a name="copyright"><h2>COPYRIGHT</h2> Copyright (c) 2004 Pat Thoyts <patthoyts@users.sourceforge.net><br> </body></html>
