IFWXLowResourceRecoveryOperation Interface

The IFWXLowResourceRecoveryOperation interface is the application filter interface that you implement to respond when a low resource failure occurs. For a description of the low resource recovery mechanism, see the Remarks section of this topic.

Syntax

interface IFWXLowResourceRecoveryOperation : IUnknown

Methods

The IFWXLowResourceRecoveryOperation interface inherits the methods of the IUnknown interface.

In addition, IFWXLowResourceRecoveryOperation defines the following method.

Method Description

Recover

Implemented so that your application filter responds appropriately to a failure caused by low resources.

Remarks

To use the low resource recovery mechanism, your filter has to register with the Microsoft Firewall service using the IFWXLowResourceRecoverer::RegisterForLowResourceRecovery method so that the filter will handle failures. When a failure occurs, the filter can check the error message to ascertain whether the failure was caused by low resource availability. If so, the filter calls the IFWXLowResourceRecoverer::SignalLowResourceFailure method, providing a cookie identifying the failure, and indicating to the Firewall service that the filter wants to recover from the failure. The Firewall service then calls the IFWXLowResourceRecoveryOperation::Recover method, which can retry the operation periodically until it succeeds.

Server Requires Windows Server 2008 R2 or Windows Server 2008 x64 Edition with SP2.
