The IFWXLowResourceRecoverer interface is the application filter interface that registers and unregisters an application filter for low resource recovery operations, and signals when a low resource recovery failure occurs. For a description of the low resource recovery process, see the Remarks section of this topic.
interface IFWXLowResourceRecoverer : IUnknown
The IFWXLowResourceRecoverer interface inherits the methods of the IUnknown interface.
In addition, IFWXLowResourceRecoverer defines the following methods.
| Method | Description |
|---|---|
|
Registers an application filter for low resource recovery operations. |
|
|
Unregisters an application filter from a low resource recovery operation. |
|
|
Signals the Microsoft Firewall service that a failure related to low resources has occurred. |
To use the low resource recovery mechanism, your filter has to register with the 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 has to call 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.
