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
