Constructor & Destructor Documentation

UDPTransmit::UDPTransmit (  Family  family = IPV4  )  [protected]

Create a UDP transmitter.

UDPTransmit::UDPTransmit (  const IPV4Address &  bind, tpport_t  port = 5005 )  [protected]

Create a UDP transmitter, bind it to a specific interface and port address so that other UDP sockets on remote machines (or the same host) may find and send UDP messages to it, and associate it with a given port on a peer host. On failure to bind, an exception is thrown. This class is only used to build the UDP Duplex. Parameters: bind  address to bind this socket to. port  number to bind this socket to.

Member Function Documentation

Error UDPTransmit::connect (  const IPV4Multicast &  mgroup, tpport_t  port )  [protected]

Associate this socket with a multicast group. Returns: 0 on success, -1 on error. Parameters: mgroup  address of the multicast group to send to. port  port number

Error UDPTransmit::connect (  const IPV4Broadcast &  subnet, tpport_t  port )  [protected]

Associate this socket with a subnet of peer hosts for subnet broadcasting. The server must be able to assert broadcast permission for the socket. Returns: 0 on success, -1 on error. Parameters: subnet  subnet address to broadcast into. port  transport port to broadcast into.

Error UDPTransmit::connect (  const IPV4Host &  host, tpport_t  port )  [protected]

Associate this socket with a specified peer host. The port number from the constructor will be used. All UDP packets will be sent to and received from the specified host. Returns: 0 on success, -1 on error. Parameters: host  address to connect socket to. port  to connect socket to. Reimplemented from UDPSocket. Reimplemented in UDPDuplex.

void UDPTransmit::endTransmitter (  void   )  [inline, protected]

Stop transmitter.

SOCKET UDPTransmit::getTransmitter (  void   )  [inline, protected]

bool UDPTransmit::isOutputReady (  unsigned long  timeout = 0l  )  [inline]

See if output queue is empty for sending more packets. Returns: true if output available. Parameters: timeout  in milliseconds to wait.

ssize_t UDPTransmit::send (  const void *  buf, size_t  len )  [inline, protected]

Transmit "send" to use "connected" send rather than sendto. Returns: number of bytes sent. Parameters: buf  address of buffer to send. len  of bytes to send. Reimplemented from UDPSocket.

Error UDPTransmit::setBroadcast (  bool  enable  )  [inline]

Reimplemented from Socket.

Error UDPTransmit::setMulticast (  bool  enable  )  [inline, protected]

Reimplemented from UDPSocket.

Error UDPTransmit::setRouting (  bool  enable  )  [inline]

Reimplemented from Socket.

Error UDPTransmit::setTimeToLive (  unsigned char  ttl  )  [inline, protected]

Error UDPTransmit::setTypeOfService (  Tos  tos  )  [inline]

ssize_t UDPTransmit::transmit (  const char *  buffer, size_t  len )  [inline]

Transmit "send" to use "connected" send rather than sendto. Note: Windows does not support MSG_DONTWAIT, so it is defined as 0 on that platform. Returns: number of bytes sent. Parameters: buffer  address of buffer to send. len  of bytes to send.
