Data Representation

Data representation describes the format used for parameters and results as they are passed between processes. To function on a variety of system architectures, RPC 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 the byte orders or structure layout conventions of the different hosts. For a detailed discussion of XDR, see Appendix A, XDR Technical Note and Appendix C, XDR Protocol Specification.
