title: Returning string from a remote server using rpcgen
body: <p>I am going through RPC tutorial and learn few techniques in rpcgen. I have the idea of adding, multiplying different data types using rpcgen.</p>
  
  <p>But I have not found any clue that how could I declare a function in .x file which will return a string. Actually I am trying to build a procedure which will return a random string(rand string array is in server). </p>
  
  <p>Can any one advise me how to proceed in this issue? It will be helpful if you advise me any tutorial regarding this returning string/pointer issue.</p>
  
  <p>Thank you in advance.</p>
