3.1.4.45 RRPC_FWGetGlobalConfig2_10 (Opnum 44)

The RRPC_FWGetGlobalConfig2_10 (Opnum 44) method retrieves the value of a global policy configuration option. The client specifies to the server from which store this value MUST be retrieved and in which specific configuration option it is interested. The method is only supported for binary versions 0x020A and 0x0214.

 unsigned long RRPC_FWGetGlobalConfig2_10(
   [in] FW_CONN_HANDLE rpcConnHandle,

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

BinaryVersion: This parameter specifies the RPC interface binary version. This implies versions of the methods and versions of the structures.

StoreType: This parameter specifies the policy store from which the client retrieves the configuration option value.

configID: This parameter specifies the specific global policy configuration option that the client is interested in retrieving.

dwFlags: This parameter is a combination of flags from the FW_CONFIG_FLAGS enumeration, which modifies the behavior of this method, as specified in the definition of the enumeration.

pBuffer: This is an input/output parameter. This parameter is a pointer to the buffer that the client provides to contain the value of the profile configuration option that is being requested.

cbData: This parameter is the size of the buffer to which the pBuffer parameter points.

pcbTransmittedLen: This is a pointer to an input and output parameter that specifies the length of the transmitted data within the buffer.

pcbRequired: This is a pointer to an output parameter that specifies the required minimum buffer size, in octets, for the method to be able to return the configuration value. This output parameter is nonzero only if the buffer (pointed to by pBuffer and whose size is cbData) was not big enough to contain the value.

pOrigin: This field is the origin of the configuration option, as specified in the FW_RULE_ORIGIN_TYPE enumeration. On success, it MUST be filled.

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.
0x00000002 ERROR_FILE_NOT_FOUND	The specific configuration option is not found within the policy. This means that it is not configured. If the option is not configured in any other store, the firewall uses a default value.
0x00000032 ERROR_NOT_SUPPORTED	The specified store type does not support this method.
0x00000057 ERROR_INVALID_PARAMETER	One of the parameters of this method either is incorrect or is required and not specified. This error can be returned because: The specific configuration option is not meant to be available in the specified store. The specified configuration option is not defined. One of the required values is not specified. The buffer is not big enough to hold the specific value.

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.
