| 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.
