Member Function Documentation

DSAP ( )

TUint8

DSAP

(

)

const [pure virtual]

Returns DSAP address of this connection object.

Return Value: DSAP address of this connection object.

DsapL ( )

TUint8

DsapL

(

)

[pure virtual]

Returns DSAP address of this connection object.

Return Value: DSAP address of this connection object.

Receive ( TRequestStatus &, TDes8 & )

void	Receive	(	TRequestStatus &	aStatus,
			TDes8 &	aBuffer
		)	[pure virtual]

Tries to receive data from remote peer. Maximum size of received data is LLCP MTU and aBuffer should be that size if it is uncertain how big data packets are going to be received.

Parameters
aStatus	Request status
aBuffer	Buffer for received data

Receive ( TDes8 & )

TInt

Receive

(

TDes8 &

aBuffer

)

[pure virtual]

Fetches data received from remote peer. Maximum size of received data is LLCP MTU and aBuffer should be that size if it is uncertain how big packets we are receiving.

Parameters
aBuffer	Buffer for received data

Return Value: System wide error code

ReceiveBufferCount ( )

TInt

ReceiveBufferCount

(

)

const [pure virtual]

Returns the amount of buffered received frames.

Return Value: Amount of buffered frames

ReceiveCancel ( )

void

ReceiveCancel

(

)

[pure virtual]

Cancels asynchronous MLlcpConnection::Receive() request.

SSAP ( )

TUint8

SSAP

(

)

const [pure virtual]

Returns SSAP address of this connection object.

Return Value: SSAP address of this connection object.

SsapL ( )

TUint8

SsapL

(

)

[pure virtual]

Returns SSAP address of this connection object.

Return Value: SSAP address of this connection object.

SupportedDataLength ( )

TInt

SupportedDataLength

(

)

[pure virtual]

Returns maximum amount of bytes that can be received in one MLlcpConnection::Receive() method.

SupportedDataLength ( )

TInt

SupportedDataLength

(

)

const [pure virtual]

Returns maximum amount of bytes that can be sent or received in one MLlcpConnection::Transmit() or MLlcpConnection::Receive() method.

Transmit ( TRequestStatus &, const TDesC8 & )

void	Transmit	(	TRequestStatus &	aStatus,
			const TDesC8 &	aData
		)	[pure virtual]

Transmits data to the remote peer.

Parameters
aData	Data to transmit

TransmitCancel ( )

void

TransmitCancel

(

)

[pure virtual]

Cancels MLlcpConnection::Transmit() request.

TransportType ( )

TLlcpConnectionType

TransportType

(

)

[pure virtual]

Returns the transport type of the connection.

TransportType ( )

TInt

TransportType

(

)

const [pure virtual]

Returns the transport type of the connection.

WaitForData ( TRequestStatus & )

void

WaitForData

(

TRequestStatus &

aStatus

)

[pure virtual]

Requests MLlcpType2Connection object to notify data received event.

Return Value: Return values for aStatus:KErrNone when connection has received atleast one data frame from the remote peer.KErrInUse when new request is issued before previous is completed.KErrNotReady when connection is not connected to the remote peer.KErrEof when remote peer has lost from the near field.

WaitForDataCancel ( )

void

WaitForDataCancel

(

)

[pure virtual]

Cancels MLlcpType2Connection::WaitForData() request.
