To write a new C server
Use the C Wrapper to generate a C server skeleton and a C server interface object. Write your C server and proceed as described under Using the C Wrapper for the Server Side (z/OS, Linux, Windows, BS2000).
Build an EntireX RPC client using any EntireX wrapper. See EntireX Wrappers. For a quick test you can:
use the IDL Tester; see EntireX IDL Tester in the Designer documentation
generate an XML mapping file (XMM) and use the XML Tester for verification; see EntireX XML Tester in the XML/SOAP Wrapper documentation
