2.2 Common Data Types

  • Article

All structures are defined in the Interface Definition Language (IDL) syntax and are marshaled as specified in [C706] Part 3. The IDL is documented in section 6.

Field types in packet diagrams are defined by the packet diagram and the field descriptions. All fields in packet diagrams are marshaled using little-endian byte ordering, unless otherwise specified.

Unless otherwise specified, all extra padding bytes MUST be set to zero (0x00) when sent and MUST be ignored upon receipt.

Note that LPWSTR or WCHAR* types specified in an IDL structure that are annotated with the [string] attribute MUST be null-terminated, as specified in [C706] section 14.3.4.

This protocol MUST indicate to the remote procedure call (RPC) runtime that it is to support the NDR transfer syntax only, as specified in [C706] Part 4. In addition to RPC base types and definitions specified in [C706] and [MS-RPCE], additional data types are defined in this section.
