Detailed Description

Write stream to an UDP socket.

Parameters:

	itemsize	The size (in bytes) of the item datatype
	host	The name or IP address of the receiving host; use NULL or None for no connection
	port	Destination port to connect to on receiving host
	payload_size	UDP payload size by default set to 1472 = (1500 MTU - (8 byte UDP header) - (20 byte IP header))
	eof	Send zero-length packet on disconnect

Constructor & Destructor Documentation

gr_udp_sink::gr_udp_sink	(	size_t	itemsize,
		const char *	host,
		unsigned short	port,
		int	payload_size,
		bool	eof
	)			`[protected]`

UDP Sink Constructor.

Parameters:

	itemsize	The size (in bytes) of the item datatype
	host	The name or IP address of the receiving host; use NULL or None for no connection
	port	Destination port to connect to on receiving host
	payload_size	UDP payload size by default set to 1472 = (1500 MTU - (8 byte UDP header) - (20 byte IP header))
	eof	Send zero-length packet on disconnect

gr_udp_sink::~gr_udp_sink ( )

Member Function Documentation

void gr_udp_sink::connect	(	const char *	host,
		unsigned short	port
	)

Change the connection to a new destination.

Parameters:

	host	The name or IP address of the receiving host; use NULL or None to break the connection without closing
	port	Destination port to connect to on receiving host

Calls disconnect() to terminate any current connection first.

void gr_udp_sink::disconnect ( )

Send zero-length packet (if eof is requested) then stop sending.

Zero-byte packets can be interpreted as EOF by gr_udp_source. Note that disconnect occurs automatically when the sink is destroyed, but not when its top_block stops.

int gr_udp_sink::payload_size ( ) [inline]

return the PAYLOAD_SIZE of the socket
