Detailed Description

A peer associated RTP socket pair for physically connected peer hosts.

This has no RTCP and assumes the receiver is connected to a known transmitter, hence no ’foreign’ packets will arrive.

Author:

David Sugar RTP peer host over UDP.

Examples:

rtpduphello.cpp.

Constructor & Destructor Documentation

RTPDuplex::RTPDuplex (const InetAddress & bind, tpport_t local, tpport_tremote)

Parameters:

bind network address this socket is to be bound
local transport port this socket is to be bound
remote peer transpor port

virtual RTPDuplex::˜RTPDuplex () [virtual]

Member Function Documentation

UDPTransmit::Error RTPDuplex::connect (const InetHostAddress & host, tpport_tport = 0)

Parameters:

host peer address
port peer port. If not specified, the same as the local is used

Returns:

socket status

Examples:

rtpduphello.cpp.

size_t RTPDuplex::getNextDataPacketSize () const [inline], [protected],[virtual]

Implements IncomingDataQueue.

SyncSource& RTPDuplex::getPeer () [protected]

Returns:

the associated peer information

bool RTPDuplex::isPendingData (microtimeout_t timeout) [inline],[protected], [virtual]

Parameters:

timeout how much time to wait for new data

Returns:

if there is some new data

Implements RTPDataQueue.

size_t RTPDuplex::recvData (unsigned char * buffer, size_t len,InetHostAddress & na, tpport_t & tp) [inline], [protected], [virtual]

Parameters:

buffer where to store the retrieved data
len how many octets to read
na Source network address.
tp Source transport port.

Returns:

number of octets read

Implements IncomingDataQueue.

size_t RTPDuplex::sendData (const unsigned char *const buffer, size_t len)[inline], [protected], [virtual]

Parameters:

buffer pointer to data to be written
len how many octets to write

Returns:

number of octets written
