Detailed Description

This class can be used to access the bundled/monitored UDP sockets using the PChannel API.

Constructor & Destructor Documentation

PMonitoredSocketChannel::PMonitoredSocketChannel	(	const PMonitoredSocketsPtr &	sockets,
		bool	shared
	)

Construct a monitored socket bundle channel.

Parameters:

shared

Monitored socket bundle to use in channel Monitored socket is shared by other channels

PMonitoredSocketChannel::PMonitoredSocketChannel	(	const PMonitoredSocketsPtr &	sockets,
		bool	shared
	)

Construct a monitored socket bundle channel.

Parameters:

shared

Monitored socket bundle to use in channel Monitored socket is shared by other channels

Member Function Documentation

virtual PBoolean PMonitoredSocketChannel::IsOpen ( ) const [virtual]

Determine if the channel is currently open. This indicates that read and write operations can be executed on the channel. For example, in the PFile# class it returns if the file is currently open.

Returns:: PTrue if the channel is open.

Reimplemented from PChannel.

virtual PBoolean PMonitoredSocketChannel::Close ( ) [virtual]

Close the channel, shutting down the link to the data source.

Returns:: PTrue if the channel successfully closed.

Reimplemented from PChannel.

virtual PBoolean PMonitoredSocketChannel::Read	(	void *	buffer,
		PINDEX	length
	)			`[virtual]`

Override of PChannel functions to allow connectionless reads

Reimplemented from PChannel.

virtual PBoolean PMonitoredSocketChannel::Write	(	const void *	buffer,
		PINDEX	length
	)			`[virtual]`

Low level write to the channel. This function will block until the requested number of characters are written or the write timeout is reached. The GetLastWriteCount() function returns the actual number of bytes written.

The GetErrorCode() function should be consulted after Write() returns PFalse to determine what caused the failure.

Returns:: PTrue if at least len bytes were written to the channel.

Parameters:

buffer

Override of PChannel functions to allow connectionless writes

Reimplemented from PChannel.

void PMonitoredSocketChannel::SetInterface ( const PString & iface )

Set the interface descriptor to be used for all reads/writes to this channel. The iface parameter can be a partial descriptor eg "%eth0".

Parameters:

iface

Interface descriptor

const PString& PMonitoredSocketChannel::GetInterface ( )

Get the current interface descriptor being used/.

bool PMonitoredSocketChannel::GetLocal	(	PIPSocket::Address &	address,
		WORD &	port,
		bool	usingNAT
	)

Get the local IP address and port for the currently selected interface.

Parameters:

port	IP address of local interface
usingNAT	Port listening on Require NAT address/port

void PMonitoredSocketChannel::SetRemote	(	const PIPSocket::Address &	address,
		WORD	port
	)

Set the remote address/port for all Write() functions.

Parameters:

port

Remote IP address Remote port number

void PMonitoredSocketChannel::SetRemote ( const PString & hostAndPort )

Set the remote address/port for all Write() functions.

Parameters:

hostAndPort

String of the form host[:port]

void PMonitoredSocketChannel::GetRemote	(	PIPSocket::Address &	addr,
		WORD &	port
	)			const `[inline]`

Get the current remote address/port for all Write() functions.

Parameters:

port

Remote IP address Remote port number

void PMonitoredSocketChannel::SetPromiscuous ( bool flag ) [inline]

Set flag for receiving UDP data from any remote address. If the flag is false then data received from anything other than the configured remote address and port is ignored.

Parameters:

flag

New flag

bool PMonitoredSocketChannel::GetPromiscuous ( ) [inline]

Get flag for receiving UDP data from any remote address.
