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.

UDPTransmit (Family family=IPV4)
Create a UDP transmitter.

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:

0 on success, -1 on error.

Parameters:

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

Reimplemented from ost::UDPSocket.

Reimplemented in ost::UDPDuplex.  

void ost::UDPTransmit::endTransmitter (void) [inline, protected]

Stop transmitter.

References ost::Socket::endSocket().  

SOCKET ost::UDPTransmit::getTransmitter (void) [inline, protected]

 

bool ost::UDPTransmit::isOutputReady (unsigned long timeout = 0l) [inline]

See if output queue is empty for sending more packets. Returns:

true if output available.

Parameters:

timeout in milliseconds to wait.

References ost::Socket::isPending(), and ost::Socket::pendingOutput.  

ssize_t ost::UDPTransmit::send (const void * buf, size_t len) [inline, protected]

Transmit 'send' to use 'connected' send rather than sendto. Returns:

number of bytes sent.

Parameters:

buf address of buffer to send.
len of bytes to send.

Reimplemented from ost::UDPSocket.

References MSG_NOSIGNAL.  

Error ost::UDPTransmit::setBroadcast (bool enable) [inline]

Reimplemented from ost::Socket.

References ost::Socket::setBroadcast().  

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

Reimplemented from ost::UDPSocket.

References ost::Socket::setMulticastByFamily().  

Error ost::UDPTransmit::setRouting (bool enable) [inline]

Reimplemented from ost::Socket.

References ost::Socket::setRouting().  

Error ost::UDPTransmit::setTimeToLive (unsigned char ttl) [inline, protected]

References ost::Socket::setTimeToLiveByFamily().  

Error ost::UDPTransmit::setTypeOfService (Tos tos) [inline]

Reimplemented from ost::Socket.

References ost::Socket::setTypeOfService().  

ssize_t ost::UDPTransmit::transmit (const char * buffer, size_t len) [inline]

Transmit 'send' to use 'connected' send rather than sendto. Note:

Windows does not support MSG_DONTWAIT, so it is defined as 0 on that platform.

Returns:

number of bytes sent.

Parameters:

buffer address of buffer to send.
len of bytes to send.
