Documentation

This class represents a particular H323 transport using TCP/IP

H323TransportTCP( H323EndPoint & endpoint, PIPSocket::Address binding = INADDR_ANY, BOOL listen = FALSE )

Create a new transport channel.

Parameters:

endpoint - H323 End Point object
binding - Local interface to use
listen - Flag for need to wait for remote to connect

~H323TransportTCP()

Destroy transport channel

virtual BOOL SetRemoteAddress( const H323TransportAddress & address )

Set default remote address to connect to. Note that this does not necessarily initiate a transport level connection, but only indicates where to connect to. The actual connection is made by the Connect() function.

virtual BOOL Connect()

Connect to the remote party

virtual BOOL Close()

Close the channel

BOOL ReadPDU( PBYTEArray & pdu )

Read a protocol data unit from the transport. This will read using the transports mechanism for PDU boundaries, for example UDP is a single Read() call, while for TCP there is a TPKT header that indicates the size of the PDU.

Parameters:

pdu - PDU read from transport

BOOL WritePDU( const PBYTEArray & pdu )

Write a protocol data unit from the transport. This will write using the transports mechanism for PDU boundaries, for example UDP is a single Write() call, while for TCP there is a TPKT header that indicates the size of the PDU.

Parameters:

pdu - PDU to write

virtual H323Transport* CreateControlChannel( H323Connection & connection )

Begin the opening of a control channel. This sets up the channel so that the remote endpoint can connect back to this endpoint.

virtual BOOL AcceptControlChannel( H323Connection & connection )

Finish the opening of a control channel. This waits for the connect backfrom the remote endpoint, completing the control channel open sequence.

BOOL IsListening() const

Indicate we are waiting from remote to connect back to us

virtual BOOL OnOpen()

This callback is executed when the Open() function is called with open channels. It may be used by descendent channels to do any handshaking required by the protocol that channel embodies.

The default behaviour is to simply return TRUE.

Returns:

Returns TRUE if the protocol handshaking is successful.

This class has no child classes.
