Responding -to Requests and Cancelling Requests

Responding to a request

The code below -shows how the observer class can respond to privacy requests by calling CLbsPrivacyController::RespondNetworkLocationRequest().

// Send a privacy response to the LBS subsystem -void CMyLbsPrivacyControllerObserver::SendResponse(TUint aRequestId, - CLbsPrivacyController::TRequestVerificationResult aResult) - { - // aRequestId is the ID of a privacy request that was previously received - iController->RespondNetworkLocationRequest(aRequestId, aResult); - }

Cancelling a privacy verification request

The code -below shows how the observer class can cancel privacy verification requests -by calling CLbsPrivacyController::CancelNetworkLocationRequest().

There -is no guarantee that a privacy request will be cancelled by calling CLbsPrivacyController::CancelNetworkLocationRequest(). -If a privacy request was first accepted and then later cancelled by a Privacy -Controller, the network may accept the request before the cancel message is -processed. The sequence diagrams in LBS Privacy -Controllerr describe this situation in more detail.

// Cancel a privacy response -void CMyLbsPrivacyControllerObserver::CancelRequest(TUint aRequestId) - { - // aRequestId is the ID of a privacy request that was previously received - iController->CancelNetworkLocationRequest(aRequestId); - }

+ + + + + +Responding +to Requests and Cancelling RequestsAs shown in the previous Privacy Controller API code examples, +a Privacy Controller has a pointer to a CLbsPrivacyController class. +The Privacy Controller uses this pointer to respond to privacy requests and +to cancel them. The simple outline code in this section shows how a Privacy +Controller calls these functions. +
