Remarks

Some fields in the FWPM_PROVIDER_CONTEXT2 structure are assigned by the system, not the caller, and are ignored in the call to FwpmProviderContextAdd2.

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. See Object Management for more information about transactions.

The caller needs FWPM_ACTRL_ADD access to the provider context's container and FWPM_ACTRL_ADD_LINK access to the provider (if any). See Access Control for more information.
