Go Systems Programming

An RPC server

This subsection will present an RPC server named RPCserver.go. As you will see in the preamble of the RPCserver.go program, the RPC server imports a package named sharedRPC, which is implemented in the sharedRPC.go file: the name of the package is arbitrary. Its contents are the following:

package sharedRPC 
 
type MyInts struct { 
   A1, A2 uint 
   S1, S2 bool 
} 
type MyInterface interface { 
   Add(arguments *MyInts, reply *int) error 
   Subtract(arguments *MyInts, reply *int) error 
} 

So, here you define a new structure that holds the signs and the values of two unsigned integers and a new interface named MyInterface.

Then, you should install sharedRPC.go, which means that you should execute the following commands before you try to use the ...
