NAME

ost::UDPTransmit -

Representing half of a two-way UDP connection, the UDP transmitter can broadcast data to another selected peer host or to an entire subnet.

SYNOPSIS

#include <socket.h>

Inherits ost::UDPSocket.

Inherited by ost::UDPDuplex.

Public Member Functions

Protected Member Functions

UDPTransmit (Family family=IPV4)
Create a UDP transmitter.
UDPTransmit (const IPV4Address &bind, tpport_t port=5005)
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.

Constructor & Destructor Documentation

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

Create a UDP transmitter.

ost::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.

ost::UDPTransmit::UDPTransmit (const IPV6Address & bind, tpport_t port = 5005) [protected]

Member Function Documentation

Error ost::UDPTransmit::connect (const IPV6Multicast & mgroup, tpport_t port) [protected]

Error ost::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 ost::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 ost::UDPTransmit::connect (const IPV6Address & host, tpport_t port) [protected]

Error ost::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:
