Example 1 with RPCReturnValue

use of inputport.rpc.duplex.RPCReturnValue in project GIPC by pdewan.

// need to worry about return values to rpc calls
// they should not be sent back
// must put the system in a special mode where these values
// are not sent
// need to synchronize this so that new messages and processed later
// bu then return values will not be trapped as they are generated
// maybe we count the number and then
// do not send back those number of them
// need to synchronize the receive call also
// could also not send calls with return values
// the only issue was that the server and count wsa not updating atomically
// leading to server not thinking it was a latecomer and sending spurious messages
