Programming with Remote Procedure Calls (RPC)

Timeout changes

After sending a request to the server, a client program waits for a default amount of time (25 seconds) to receive a reply. This timeout may be changed using the clnt_control routine. (See rpc(3rpc).)

NOTE: When considering timeout periods, be sure to allow for the minimal amount of time required for ``round trip'' communications over the network.

This is a small code fragment to illustrate the use of clnt_control:

   struct timeval tv;
   CLIENT *cl;
   
   cl = clnt_create("somehost", SOMEPROG, SOMEVERS, "visible");
   if (cl == NULL) {
   	exit(1);
   }
   tv.tv_sec = 60;	/* change timeout to 1 minute */
   tv.tv_usec = 0;
   clnt_control(cl, CLSET_TIMEOUT, &tv);
