In this case example, the client enumerates rules in the current profile and filters by FW_RULE_STATUS_CLASS_OK and FW_RULE_STATUS_CLASS_PARTIALLY_IGNORED.

 PFW_RULE pRules = NULL;
 DWORD dwNumRules = 0;
  
     DWORD 
     RRPC_FWEnumFirewallRules(
         [in] FW_CONN_HANDLE          rpcConnHandle = rpcBinding ,
         [in] FW_POLICY_STORE_HANDLE  hPolicyStore = hStore, 
         [in] DWORD                   dwFilteredByStatus =
  FW_RULE_STATUS_CLASS_OK | FW_RULE_STATUS_CLASS_PARTIALLY_IGNORED,
         [in] DWORD                   dwProfileFilter = FW_PROFILE_TYPE_CURRENT,
         [in] WORD                    wFlags = 0
         [out, ref] DWORD            *pdwNumRules = &dwNumRules,
         [out] PFW_RULE         *ppRules = &pRules
         );
