DataIn Event

Fired when data is received.

Syntax

mcast.on('DataIn', [callback])

Callback

The 'callback' is called when the 'DataIn' event is emited.

function(e){ }

The argument 'e' has the following properties:

e.datagram (buffer)
e.sourceAddress
e.sourcePort

Remarks

The DataIn event is fired every time a new datagram is received.

Datagram contains the packet as sent by the remote host.

SourceAddress contains the IP number (Internet address) of the remote host, and SourcePort contains the port from which the packet originated.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.
