Here is a quick look at the functions most commonly used from CP's RPC library.

• public static Bool amIMaster()
  - returns true if the client is master, false otherwise
• public static void sendApplSpecificMsgWithDist (SFNode obj, string methodName, string argument, int distrMethod);
  - sends a request to other clients to call a method locally
  Parameters :
  • SFNode obj : the shared object
  • string methodName : the name of the method which will be invoked locally on a client receiving this call
  • string "argument" : set of parameters encoded as a String. The receiver must decode this.
  • int distrMethod : a flag which specifies the clients who get this message
