3.1.4.44 RRPC_FWEnumAdapters (Opnum 43)

The RRPC_FWEnumAdapters (Opnum 43) method requests the server to return all the networks interfaces that the host with the firewall and advanced security component has. The only method supported is binary version 0x020A.

 unsigned long RRPC_FWEnumAdapters(
   [in] FW_CONN_HANDLE rpcConnHandle,
   [in] FW_POLICY_STORE_HANDLE hPolicy,
   [out] unsigned long pdwNumAdapters,
   [out, size_is(,*pdwNumAdapters)] 
     PFW_ADAPTER* ppAdapters
 );

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.

pdwNumAdapters: This is an output parameter that, on success, MUST be equal to the number of networks returned.

ppAdapters: This is an output parameter that, on success, contains an array of FW_ADAPTER 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

A 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.
