<return type="int" enum="Error" />
<param index="0" name="port" type="int" />
<param index="1" name="bind_address" type="String" default=""*"" />
<description>
Listen on the [code]port[/code] binding to [code]bind_address[/code].
If [code]bind_address[/code] is set as [code]"*"[/code] (default), the server will listen on all available addresses (both IPv4 and IPv6).
If [code]bind_address[/code] is set as [code]"0.0.0.0"[/code] (for IPv4) or [code]"::"[/code] (for IPv6), the server will listen on all available addresses matching that IP type.
If [code]bind_address[/code] is set to any valid address (e.g. [code]"192.168.1.101"[/code], [code]"::1"[/code], etc), the server will only listen on the interface with that addresses (or fail if no interface with the given address exists).
</description>

<return type="void" />
<description>
Stops listening.
</description>
