cPacket * RealworldApp::decapsulate	(	char *	buf,
		uint32_t	length,
		sockaddr *	addr,
		socklen_t	addrlen
	)			`[protected, virtual]`

Parses data received from the (realworld) network and converts it into a cMessage.

Parameters:

	buf	A pointer to the data to be parsed
	length	The lenght of the buffer in bytes
	addr	Ignored (deleted)
	addrlen	Ignored

Returns:: The parsed message

char * RealworldApp::encapsulate	(	cPacket *	msg,
		unsigned int *	length,
		sockaddr **	addr,
		socklen_t *	addrlen
	)			`[protected, virtual]`

Converts an IP datagram to a data block for sending it to the (realworld) network.

Parameters:

	msg	A pointer to the message to be converted
	length	A pointer to an int that will hold the length of the converted data
	addr	Ignored (set to 0)
	addrlen	Ignored (set to 0)

Returns:: A pointer to the converted data

Implements RealworldConnector.
