ost::UDPDuplex - UDP duplex connections impliment a bi-directional point-to-point UDP session between two peer hosts.

#include <socket.h>

Inherits ost::UDPTransmit, and ost::UDPReceive.


UDPDuplex (const IPV4Address &bind, tpport_t port)
Create a UDP duplex as a pair of UDP simplex objects bound to alternating and interconnected port addresses. UDPDuplex (const IPV6Address &bind, tpport_t port)
Error connect (const IPV4Host &host, tpport_t port)
Associate the duplex with a specified peer host. Error connect (const IPV6Host &host, tpport_t port)
Error disconnect (void)
Disassociate this duplex from any host connection.

UDP duplex connections impliment a bi-directional point-to-point UDP session between two peer hosts.

Two UDP sockets are typically used on alternating port addresses to assure that sender and receiver data does not collide or echo back. A UDP Duplex is commonly used for full duplex real-time streaming of UDP data between hosts.

ost::UDPDuplex::UDPDuplex (const IPV4Address & bind, tpport_t port)

Create a UDP duplex as a pair of UDP simplex objects bound to alternating and interconnected port addresses.

Parameters

bind address to bind this socket to.
port number to bind sender.

ost::UDPDuplex::UDPDuplex (const IPV6Address & bind, tpport_t port)

Error ost::UDPDuplex::connect (const IPV4Host & host, tpport_t port)

Associate the duplex with a specified peer host. Both the sender and receiver will be interconnected with the remote host.

Returns

0 on success, error code on error.

Parameters

host address to connect socket to.
port number to connect socket to.

Error ost::UDPDuplex::connect (const IPV6Host & host, tpport_t port)

Error ost::UDPDuplex::disconnect (void)

Disassociate this duplex from any host connection. No data should be read or written until a connection is established.

Returns

0 on success, error code on error.
