| BOOL H323TransportUDP::SetRemoteAddress | ( | const H323TransportAddress & | address | ) | [virtual] |
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.
Implements H323Transport.

| BOOL H323TransportUDP::Connect | ( | ) | [virtual] |
Connect to the remote party.

| void H323TransportUDP::SetPromiscuous | ( | PromisciousModes | promiscuous | ) | [virtual] |
Set read to promiscuous mode. Normally only reads from the specifed remote address are accepted. This flag allows packets to be accepted from any remote, provided the underlying protocol can do so.
The Read() call may optionally set the remote address automatically to whatever the sender host of the last received message was.
Default behaviour sets the internal flag, so that Read() operates as described.

| H323TransportAddress H323TransportUDP::GetLastReceivedAddress | ( | ) | const [virtual] |
Get the transport address of the last received PDU.
Default behaviour returns the lastReceivedAddress member variable.

References H323Transport::GetLastReceivedAddress(), and lastReceivedAddress.
| BOOL H323TransportUDP::ReadPDU | ( | PBYTEArray & | pdu | ) | [virtual] |
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.
| pdu | PDU read from transport |

| BOOL H323TransportUDP::ExtractPDU | ( | const PBYTEArray & | pdu, | |
| PINDEX & | len | |||
| ) | [virtual] |
Extract a protocol data unit from the transport
Implements H323Transport.
Definition at line 2025 of file transports.cxx.
| BOOL H323TransportUDP::WritePDU | ( | const PBYTEArray & | pdu | ) | [virtual] |
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.
| pdu | PDU to write |
Implements H323Transport.

| H323RasPDU & | pdu, | |||
| const H323TransportAddress & | address | |||
| ) | [virtual] |
Discover a Gatekeeper on the local network. This locates a gatekeeper on the network and associates this transport object with packet exchange with that gatekeeper. This broadcasts a UDP packet on the local network to find the gatekeeper's IP address.
| gk | Gatekeeper to set on discovery. |
| pdu | GatekeeperRequest PDU |
| address | Address of gatekeeper (if present) |
