Remarks

If the caller supplies a null security descriptor, the system will assign a default security descriptor.

Boot-time objects are added to the Base Filtering Engine (BFE) when the TCP/IP driver starts, and are removed once the BFE finishes initialization. Persistent objects are added when the BFE starts. If a policy provider has a persistent policy that is not intended to be enforced if its associated service is disabled, the caller can specify an optional service name in the FWPM_PROVIDER0 structure. This service then owns the persistent policy object. At start, the BFE only adds the following types of persistent objects to the system.

  • The object is not associated with a provider.
  • The object has an associated provider that does not specify a service name.
  • The object has an associated provider and an associated service set to auto-start.
This function cannot be called from within a read-only transaction. It will fail with FWP_E_INCOMPATIBLE_TXN. See Object Management for more information about transactions.

The caller needs FWPM_ACTRL_ADD access to the provider's container. See Access Control for more information.

FwpmProviderAdd0 is a specific implementation of FwpmProviderAdd. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
