The Server Side
For the server side, the programmer writes application routines that implement the operations defined in the IDL file. For example, in the banking application, a database lookup might implement the operation to read an account balance. The server stub, generated by the IDL compiler, is linked with the server application code. The server stub unpacks the arguments and makes the call to the application routine as if the client program had called it directly. The server side of the application contains the bulk of the RPC code that needs to be written by the distributed application programmer.
