2.2.3 EFSRPC Raw Data Format
The EFSRPC raw data format is used by the EFSRPC raw methods. The output of the EfsRpcReadFileRaw method MUST conform to this format. The input to the EfsRpcWriteFileRaw method MUST conform to the EFSRPC Raw Data Format. The details of this format are implementation dependent. An EFSRPC client SHOULD NOT parse this format and SHOULD NOT rely on it having any particular structure. An EFSRPC server MUST validate input data passed to it by the EfsRpcWriteFileRaw method, and SHOULD abort the EfsRpcWriteFileRaw operation with an RPC exception if this data is in an unsupported format.
The EFSRPC Raw Data Format SHOULD be formatted as follows.
