Detailed Description¶
Representing half of a two-way UDP connection, the UDP receiver can receive data from another peer host or subnet. This class is used exclusivily to derive the UDPDuplex. Author:David Sugar dyfet@ostel.com Unreliable Datagram Peer

Constructor & Destructor Documentation¶
ost::UDPReceive::UDPReceive (const IPV4Address &bind, tpport_tport) [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.
ost::UDPReceive::UDPReceive (const IPV6Address &bind, tpport_tport) [protected]¶
Member Function Documentation¶
Error ost::UDPReceive::connect (const IPV4Host &host, tpport_tport) [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.

End receiver. References ost::Socket::endSocket().SOCKET ost::UDPReceive::getReceiver (void) const [inline], [protected]¶
bool ost::UDPReceive::isInputReady ( timeout_ttimeout = 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_ttimeout) [inline], [protected]¶
Check for pending data. Returns:true if data is waiting.
Parameters:
timeout in milliseconds.

Error ost::UDPReceive::join (const IPV4Multicast &ia) [inline], [protected]¶
References ost::Socket::join().Error ost::UDPReceive::join (const IPV6Multicast &ia) [inline], [protected]¶
References ost::Socket::join().ssize_t ost::UDPReceive::receive (void *buf, size_tlen) [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.
