3.1.4.37 RRPC_FWEnumMainModeRules (Opnum 36)

  • Article

The RRPC_FWEnumMainModeRules (Opnum 36) method requests the server to return all the main mode rules contained in the store referenced by the hPolicy handle. The method returns a linked list of all the main mode rule objects. The only method supported is binary version 0x020A.

 unsigned long RRPC_FWEnumMainModeRules(
   [in] FW_CONN_HANDLE rpcConnHandle,
   [in] FW_POLICY_STORE_HANDLE hPolicy,
   [in] unsigned long dwFilteredByStatus,
   [in] unsigned long dwProfileFilter,
   [in] unsigned short wFlags,
   [out, ref] unsigned long* pdwNumRules,
   [out] PFW_MM_RULE* ppMMRules
 );

rpcConnHandle: This parameter is an RPC binding handle that connects to the RPC interface of the Firewall and Advanced Security Protocol.

hPolicy: This input parameter is an FW_POLICY_STORE_HANDLE data type. The data type MUST contain an opened policy store handle, successfully opened with the RRPC_FWOpenPolicyStore (Opnum 0) method. This handle MUST be of the FW_STORE_TYPE_DYNAMIC store.

dwFilteredByStatus: This parameter is a combination of flags from the FW_RULE_STATUS_CLASS enumeration. This method uses this bitmask to determine which rules will be returned. Rules that contain a status code of the class specified by this parameter will be returned in the linked list.

dwProfileFilter: This parameter is a combination of flags from the FW_PROFILE_TYPE enumeration. This method also uses this parameter to determine which rules will be returned. Rules that contain a profile specified by this parameter will be returned in the linked list.

wFlags: This parameter is a combination of flags from the FW_ENUM_RULES_FLAGS enumeration, which modifies the behavior of the method and performs operations on the rules before returning them in the linked list.

pdwNumRules: This is an output parameter that on success MUST be equal to the number of rules returned.

ppMMRules: This is an output parameter that on success contains a linked list of FW_MM_RULE data types.

Return Values: The method returns 0 if successful; if it fails, it returns a nonzero error code. The field can take any specific error code value, as specified in [MS-ERREF]. The following return values are common.

Return value/code

Description

0x00000005

ERROR_ACCESS_DENIED

The client does not have the required credentials to call the method.

0x00000057

ERROR_INVALID_PARAMETER

One of the parameters for this method is incorrect, or is required but not specified. This error can be returned in the following cases:

- One of the parameters did not meet the required constraints.

- The dwProfileFilter parameter contains invalid profiles.

Exceptions Thrown: No exceptions are thrown beyond those thrown by the underlying RPC protocol, as specified in [MS-RPCE]. If any lower-layer errors are reported by RPC exception, this exception is converted to an error code and reported to higher-layer protocols via the return value.

The server MUST validate that the client is authorized to perform the requested operation (as defined in section 3.1.4) before executing this method.
