DLL Interface Home C: Connect to the Server To connect to the VistA M Server from your C program:

1. Set the server and port to connect to:

// Set the Server and Port properties to determine where to connect. RPCBPropSet(RPCBroker,"Server", "BROKERSERVER"); RPCBPropSet(RPCBroker, "ListenerPort", "9200");

2. Set the Connected property to true; this attempts a connection to the VistA M Server:

// Set the Connected property to True, to connect. RPCBPropSet(RPCBroker, "Connected", "1");

3. Check if you are still connected. If so, you can continue (your connection was made). If not, you should quit or branch accordingly:

// If still connected, can continue. RPCBPropGet(RPCBroker, "Connected", Value); if (atoi(Value) != 1) return false;

4. Attempt to create context for your application's "B"-type option. If you can't create context, you should quit or branch accordingly. If RPCBCreateContext returns True, then you are ready to call all RPCs registered to your application's "B"-type option:

// Create Context for your application's option (in this case, XWB EGCHO). result = RPCBCreateContext(RPCBroker, "XWB EGCHO"); return result;
