virtual void MToTuneComplete(TInt aError)=0;
Description
Tune complete event. This event is asynchronous and is received after a call to the Tune method.
Parameters
TInt aError |
A standard system error
|
|
MToTunerEvent(TEventType,TInt,TAny *)
virtual void MToTunerEvent(TEventType aType, TInt aError, TAny *aAdditionalInfo)=0;
Description
Passes an asychronous event to the tuner client.
Parameters
MMMTunerObserver::TEventType aType |
The type of event. See enumeration MMMTunerObserver::TEventType for more information about when the event types mean.
|
TInt aError |
An error code associated with the event.
|
TAny *aAdditionalInfo |
Any additional information associated with the event, or NULL if no such additional information exists.
|
|
TEventType
Description
The TEvent enumeration is used to indicate which type of event is being sent to the client. Each event will be associated
with an error code and potentially some addition information, and will be passed to the client via method MMMTunerObserver::MToTunerEvent(TEventType,TInt,TAny *)
.
ETunerEvent |
An event relating to the tuner itself. Any error other than KErrNone associated with this event type may indicate that the
tuner cannot be used anymore.
No additional information is associated with this type of event.
|
EControlEvent |
An event arising from the tuner policy. An error of KErrNone associated with this event type indicates that control of the
tuner has been granted to the client, and an error of KErrAccessDenied indicates that control has been denied or revoked from
the client.
Once control of the tuner has been granted via an event of this type, subsequent calls to Tune will succeed. To request an
such event, a client should call NotifyTunerControl.
Control of the tuner is retained until is is released, or pre-empted by a higher priority client. If this client no longer
needs control of the tuner, it must be released to allow other clients access.
No additional information is associated with this type of event.
