CPosIntGpsHwStatus Class Reference
The CPosIntGpsHwStatus class is used for updating and checking the current status of integrated GPS HW.
Users who wish to update the HW status and do not wish to receive callbacks should instantiate the interface with the NewL or NewLC methods. Doing so will require WriteDeviceData. Updating HW status is usually performed by the HW integration layer.
Users who wish to be notified of changes to the HW status should use the overloaded NewL or NewLC functions that take MPosIntGpsHwStatusObserver as an argument. Doing so will not require any capabilities. Checking HW status is usually performed by the UI, and applications.
Multiple applications may be notified of HW status updates but only one should change the HW status.

GetStatusL(TIntGpsHwStatus &)
Get the current status of Integrated GPS HW.
- leave
- KErrPermissionDenied, if the caller process doesn't pass the Read Policy. KErrNotFound, if the property has not been defined. Or any other error code.
NewL()
Static constructor. This function is usually used by the Hardware Integration Layer.
- capability
- WriteDeviceData
NewL(MPosIntGpsHwStatusObserver &)
Static constructor. This function is usually used by the UI and applications. It Subscribes to callbacks which fire when the status of Integrated GPS HW changes This is the overload for NewL()
NewLC()
Static constructor, leaves class on the cleanup stack. This function is usually used by the Hardware Integration Layer. This is the overload for
NewL() - capability
- WriteDeviceData
NewLC(MPosIntGpsHwStatusObserver &)
Static constructor, leaves class on the cleanup stack. This function is usually used by the UI and applications. It subscribes to callbacks which fire when the status of Integrated GPS HW changes This is the overload for NewLC()
SetStatusL(TIntGpsHwStatus)
Updates information about current status of Integrated GPS HW.
- capability
- WriteDeviceData
- leave
- KErrArgument, aStatus is not one of the values defined in TTechnologyStatus
operator=(const CPosIntGpsHwStatus &)
