Public Methods
int	receive (void *buf, size_t len)
	Receive a data packet from the connected peer host.
bool	isInputReady (timeout_t timeout=TIMEOUT_INF)
	See if input queue has data packets available.
Protected Methods
	UDPReceive (const InetAddress &bind, tpport_t port)
	Create a UDP receiver, 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.
Error	connect (const InetHostAddress &host, tpport_t port)
	Associate this socket with a specified peer host.
Error	disconnect (void)
	Disassociate this socket from any host connection.
bool	isPendingReceive (timeout_t timeout)
	Check for pending data.
void	endReceiver (void)
	End receiver.
SOCKET	getReceiver (void)
Error	setRouting (bool enable)
Error	setMulticast (bool enable)
Error	join (const InetMcastAddress &ia)
Error	drop (const InetMcastAddress &ia)

Constructor & Destructor Documentation

ost::UDPReceive::UDPReceive (  const InetAddress &    bind, tpport_t    port )  [protected]

Create a UDP receiver, 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. Parameters: bind  address to bind this socket to. port  number to bind this socket to.

Member Function Documentation

Error ost::UDPReceive::connect (  const InetHostAddress &    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 received from the specified host. Returns: 0 on success, -1 on error. Parameters: host  host network address to connect socket to. port  host transport port to connect socket to. Reimplemented in ost::UDPDuplex.

Error ost::UDPReceive::disconnect (  void    )  [protected]

Disassociate this socket from any host connection. No data should be read or written until a connection is established. Reimplemented in ost::UDPDuplex.

Error ost::UDPReceive::drop (  const InetMcastAddress &    ia )  [inline, protected]

Reimplemented from ost::Socket.

void ost::UDPReceive::endReceiver (  void    )  [inline, protected]

End receiver.

SOCKET ost::UDPReceive::getReceiver (  void    )  [inline, protected]

bool ost::UDPReceive::isInputReady (  timeout_t    timeout = TIMEOUT_INF )  [inline]

See if input queue has data packets available. Returns: true if data packets available. Parameters: timeout  in milliseconds.

bool ost::UDPReceive::isPendingReceive (  timeout_t    timeout )  [inline, protected]

Check for pending data. Returns: true if data is waiting. Parameters: timeout  in milliseconds.

Error ost::UDPReceive::join (  const InetMcastAddress &    ia )  [inline, protected]

Reimplemented from ost::Socket.

int ost::UDPReceive::receive (  void *    buf, size_t    len )  [inline]

Receive a data packet from the connected peer host. Returns: num of bytes actually received. Parameters: buf  address of data receive buffer. len  size of data receive buffer. Reimplemented from ost::UDPSocket.

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

Reimplemented from ost::Socket.

Error ost::UDPReceive::setRouting (  bool    enable )  [inline, protected]

Reimplemented from ost::Socket.
