Remarks

Some fields in the FWPM_CALLOUT0 structure are assigned by the system, not the caller, and are ignored in the call to FwpmCalloutAdd0. If the caller supplies a null security descriptor, the system will assign a default security descriptor.

This function cannot be called from within a read-only transaction. It will fail with FWP_E_INCOMPATIBLE_TXN.

The caller needs FWPM_ACTRL_ADD access to the callout's container, FWPM_ACTRL_ADD_LINK access to the provider (if any), and FWPM_ACTRL_ADD_LINK access to the applicable layer. See WFP Access Right Identifiers for more information.

To add a filter that references a callout, invoke the functions in the following order.

  1. Call FwpsCalloutRegister (documented in the Windows Driver Kit), to register the callout with the filter engine.
  2. Call FwpmCalloutAdd0 to add the callout to the system.
  3. Call FwpmFilterAdd0 to add the filter that references the callout to the system.

By default, filters that reference callouts that have been added but have not yet registered with the filter engine are treated as Block filters.
