TInt DDriver1Channel::RequestUserHandle	(	DThread *	aThread,
		TOwnerType	aType
	)			[virtual]

Called when a user thread requests a handle to this channel.

Parameters:

	aThread	Name of thread
	aType	Determines whether the requested handle is thread or process relative.

Returns:

KErrNone if successful, otherwise one of the other system wide error codes.

TInt DDriver1Channel::DoCreate	(	TInt	aUnit,
		const TDesC8 *	anInfo,
		const TVersion &	aVer
	)			[virtual]

Second stage constructor called by the kernel's device driver framework. This is called in the context of the user thread (client) which requested the creation of a Logical Channel (e.g. through a call to RBusLogicalChannel::DoCreate()). The thread is in a critical section.

Parameters:

	aUnit	The unit argument supplied by the client to RBusLogicalChannel::DoCreate().
	aInfo	The info argument supplied by the client to RBusLogicalChannel::DoCreate().
	aVer	The version argument supplied by the client to RBusLogicalChannel::DoCreate().

Returns:

KErrNone if successful, otherwise one of the other system wide error codes.

void DDriver1Channel::HandleMsg

(

TMessageBase *

aMsg

)

[virtual]

Process a message for this logical channel. This function is called in the context of a DFC thread.

Parameters:

aMsg

The message to process. The iValue member of this distinguishes the message type: iValue==ECloseMsg, channel close message iValue==KMaxTInt, a 'DoCancel' message iValue>=0, a 'DoControl' message with function number equal to iValue iValue<0, a 'DoRequest' message with function number equal to ~iValue

(

TInt

aResult

)

[virtual]

Called by PDD from ISR to indicate that a SendData operation has completed.

Definition at line 445 of file driver1_ldd.cpp.

void DDriver1Channel::ReceiveDataComplete

(

TInt

aResult

)

[virtual]

Called by PDD from ISR to indicate that a ReceiveData operation has completed.
