DataReceivedNotificationCancel ( )

IMPORT_C TInt

DataReceivedNotificationCancel

(

)

Remove the additional notification that this request would have generated

Returns: KErrNone, or one of the system-wide error codes

DataReceivedNotificationRequest ( TUint, TUint )

IMPORT_C TInt	DataReceivedNotificationRequest	(	TUint	aRequestedGranularity,
			TUint	aRequestedNotificationVolume
		)

Receive a request for a notification after a given volume of data has been received on the sub-connection

Parameter	Description
aRequestedGranularity	The amount of data to be received after which the notification will occur (but see notes); this is relative to the current volume of data received
aRequestedNotificationVolume	The absolute amount of data that should be received before we send a notification; only used if aRequestedGranularity is zero

Returns: KErrNone, or one of the system-wide error codes

DataSentNotificationCancel ( )

IMPORT_C TInt

DataSentNotificationCancel

(

)

Remove the additional notification that this request would have generated

Returns: KErrNone, or one of the system-wide error codes

DataSentNotificationRequest ( TUint, TUint )

IMPORT_C TInt	DataSentNotificationRequest	(	TUint	aRequestedGranularity,
			TUint	aRequestedNotificationVolume
		)

Receive a request for a notification after a given volume of data has been sent on the sub-connection

Parameter	Description
aRequestedGranularity	The amount of data to be sent after which the notification will occur (but see notes); this is relative to the current volume of data sent
aRequestedNotificationVolume	The absolute amount of data that should be sent before we send a notification; only used if aRequestedGranularity is zero

Returns: KErrNone, or one of the system-wide error codes

DataTransferred ( TUint &, TUint & )

IMPORT_C TInt	DataTransferred	(	TUint &	aUplinkVolume,
			TUint &	aDownlinkVolume
		)

Calculate out how much data has been sent and received on the sub-connection

Parameter	Description
aUplinkVolume	On return, contains the amount of data sent on this subconnection
aDownlinkVolume	On return, contains the amount of data received on this subconnection

Returns: KErrNone if successful, otherwise one of the system-wide error codes

DataTransferredCancel ( )

IMPORT_C TInt

DataTransferredCancel

(

)

Cancel a request for data transfer information

Returns: ETrue to indicate that the operation is completed here

DeRegisterClient ( MConnDataTransferNotify & )

IMPORT_C void

DeRegisterClient

(

MConnDataTransferNotify &

aClient

)

De-register a client

Parameter	Description
aClient	Reference to the MConnDataTransferNotify derived class as the client
