Member Function Documentation

virtual std::string uhd::transport::udp_simple::get_recv_addr ( void  )

pure virtual

Get the last IP address as seen by recv(). Only use this with the broadcast socket.

static sptr uhd::transport::udp_simple::make_broadcast ( const std::string &  addr, const std::string &  port  )

static

Make a new broadcasting udp transport: This transport can send udp broadcast datagrams and receive datagrams from multiple sources. The primary usage for this transport will be to discover devices.

The address will be resolved, it can be a host name or ipv4. The port will be resolved, it can be a port type or number.

Parameters

addr	a string representing the destination address
port	a string representing the destination port

static sptr uhd::transport::udp_simple::make_connected ( const std::string &  addr, const std::string &  port  )

static

Make a new connected udp transport: This transport is for sending and receiving between this host and a single endpoint. The primary usage for this transport will be control transactions. The underlying implementation is simple and portable (not fast).

The address will be resolved, it can be a host name or ipv4. The port will be resolved, it can be a port type or number.

Parameters

addr	a string representing the destination address
port	a string representing the destination port

static uart_iface::sptr uhd::transport::udp_simple::make_uart ( sptr  udp )

static

Make a UART interface from a UDP transport.

Parameters

udp	the UDP transport object

Returns

a new UART interface

virtual size_t uhd::transport::udp_simple::recv ( const boost::asio::mutable_buffer &  buff, double  timeout = 0.1  )

pure virtual

Receive into the provided buffer. Blocks until data is received or a timeout occurs.

Parameters

buff	a mutable buffer to receive into
timeout	the timeout in seconds

Returns

the number of bytes received or zero on timeout

virtual size_t uhd::transport::udp_simple::send ( const boost::asio::const_buffer &  buff )

pure virtual

Send a single buffer. Blocks until the data is sent.

Parameters

buff	single asio buffer

Returns

the number of bytes sent

const size_t uhd::transport::udp_simple::mtu = 1500 - 20 - 8
