Detailed Description

A socket channel that uses the UDP transport on the Internet Protocol.

Constructor & Destructor Documentation

PUDPSocket::PUDPSocket (  WORD    port = 0 )

Create a UDP socket. If a remote machine address or a "listening" socket is specified then the channel is also opened. Parameters: port  Port number to use for the connection.

PUDPSocket::PUDPSocket (  PQoS *    qos, WORD    port = 0 )

Parameters: port  Pointer to a QOS structure for the connection Port number to use for the connection.

PUDPSocket::PUDPSocket (  const PString &    service, PQoS *    qos = NULL )

Parameters: qos  Service name to use for the connection. Pointer to a QOS structure for the connection

PUDPSocket::PUDPSocket (  const PString &    address, WORD    port )

Parameters: port  Address of remote machine to connect to. Port number to use for the connection.

PUDPSocket::PUDPSocket (  const PString &    address, const PString &    service )

Parameters: service  Address of remote machine to connect to. Service name to use for the connection.

Member Function Documentation

virtual BOOL PUDPSocket::ApplyQoS (    )  [protected, virtual]

BOOL PUDPSocket::Connect (  const PString &    address )  [virtual]

Override of PSocket functions to allow connectionless writes Parameters: address  Address of remote machine to connect to. Reimplemented from PIPSocket. Reimplemented in PSocksUDPSocket.

void PUDPSocket::GetLastReceiveAddress (  Address &    address, WORD &    port )

Get the address of the sender in the last connectionless Read(). Note that thsi only applies to the Read() and not the ReadFrom() function. Parameters: port  IP address to send packets. Port to send packets.

virtual const char* PUDPSocket::GetProtocolName (    )  [protected, virtual]

This function returns the protocol name for the socket type. Implements PSocket.

void PUDPSocket::GetSendAddress (  Address &    address, WORD &    port )

Get the address to use for connectionless Write(). Parameters: port  IP address to send packets. Port to send packets.

virtual BOOL PUDPSocket::ModifyQoSSpec (  PQoS *    qos )  [virtual]

Change the QOS spec for the socket and try to apply the changes Parameters: qos  QoS specification to use

virtual BOOL PUDPSocket::OpenSocket (  int    ipAdressFamily )  [protected, virtual]

Implements PIPSocket.

virtual BOOL PUDPSocket::OpenSocket (    )  [protected, virtual]

Implements PSocket.

virtual int PUDPSocket::OpenSocketGQOS (  int    af, int    type, int    proto )  [protected, virtual]

BOOL PUDPSocket::Read (  void *    buf, PINDEX    len )  [virtual]

Override of PChannel functions to allow connectionless reads Parameters: len  Pointer to a block of memory to read. Number of bytes to read. Reimplemented from PSocket.

void PUDPSocket::SetSendAddress (  const Address &    address, WORD    port )

Set the address to use for connectionless Write() or Windows QoS Parameters: port  IP address to send packets. Port to send packets.

BOOL PUDPSocket::Write (  const void *    buf, PINDEX    len )  [virtual]

Override of PChannel functions to allow connectionless writes Parameters: len  Pointer to a block of memory to write. Number of bytes to write. Reimplemented from PChannel.
