Microsoft RPC
Microsoft RPC (Microsoft Remote Procedure Call) is a modified version of DCE/RPC. Additions include partial support for UCS-2 (but not Unicode) strings, implicit handles, and complex calculations in the variable-length string and structure paradigms already present in DCE/RPC. == Example == The DCE 1.0 reference implementation only allows such constructs as size_is(len), or possibly size_is(len-1). MSRPC allows much more complex constructs such as size_is(len / 2 - 1) and even length_is ((max & ~0x7) + 0x7), a common expression in DCOM IDL files.
