GR_CORE_API gr_udp_sink_sptr | gr_make_udp_sink (size_t itemsize, const char *host, unsigned short port, int payload_size, bool eof) |
Write stream to an UDP socket.
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 |

void gr_udp_sink::connect | ( | const char * | host, |

) |
Change the connection to a new destination.
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.
