Protected Member Functions

UDPReceive (const IPV4Address &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.

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.

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.
