<h1>The shout command</h1>



<b>shout</b> ?<i>options</i>? <i>host</i> <i>port</i> <i>password</i>



The <b>shout</b> command opens a network socket to an icecast or shoutcast audio streaming server. The command returns a channel identifier that may be used in future invocations of commands like <b>puts</b> and <b>flush</b>.

The library takes care of stream synchronization. If data is provided too quickly, a <b>puts</b> or <b>flush</b> command will block as required. To avoid blocking, an application may make use of the <i>writable</i> fileevent. That event fires whenever the stream is ready to handle more data.

The following options may also be present before <u>host</u> to specify additional information about the connection:
