Detailed Description of Functions

What follows is a detailed look at each request server RPC function call. In the examples provided, the use of the M&C RPC++ library classes is assumed, specifically, the declaration

      RPCclient *CL;
      CL = new RPCclient(ZIYSERVICE, ZIYSERVICEVERS, (char *)RPCHost.c_str());

or one like it should be assumed. Also, note that whenever a parameter structure with a string is used (which is virtually every one of them,) the string needs to be set to the global null_str, which is an empty string (a string of zero length, NOT a NULL pointer!) This is because the XDR library will crash if an actual string object is not provided, regardless of whether the string is used or not.
