2.2 Common Data Types
This section specifies the syntax of EFSRPC data types. In addition to the RPC base types and definitions specified in [C706] and [MS-DTYP], the additional data types described in the following sections are defined in the Microsoft Interface Definition Language (MIDL) specification for this RPC interface. This protocol MUST indicate to the RPC runtime that it is to support the NDR20 transfer syntax only, as specified in [C706] Part 4.
This specification uses GUID structures as specified in [MS-DTYP] section 184.108.40.206.
