Data Representation

Data representation describes the format used for parameters and results as they are passed between processes. For RPC to function on a variety of system architectures requires a standard data representation. TI-RPC uses external data representation (XDR). XDR is a machine-independent data description and encoding protocol. Using XDR, RPC can handle arbitrary data structures, regardless of different hosts' byte orders or structure layout conventions. For a detailed discussion of XDR, see Appendix C, XDR Protocol Specification, and Appendix A, XDR Technical Note.
