Member Function Documentation

virtual void gr::blocks::udp_sink::connect	(	const std::string &	host,
		int	port
	)		[pure virtual]

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.

Implemented in gr::blocks::udp_sink_impl.

virtual void gr::blocks::udp_sink::disconnect

(

)

[pure virtual]

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.

Implemented in gr::blocks::udp_sink_impl.

static sptr gr::blocks::udp_sink::make	(	size_t	itemsize,
		const std::string &	host,
		int	port,
		int	payload_size = 1472,
		bool	eof = true
	)		[static]

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

virtual int gr::blocks::udp_sink::payload_size

(

)

[pure virtual]

return the PAYLOAD_SIZE of the socket

Implemented in gr::blocks::udp_sink_impl.
