Call an RPC to a specific client

hello everyone, i'd like to ask what parameters should put in the RPC to call to a specific client?

Im using the server to call an RPC on each client to send them their unique integer ID.

the code is somewhat like this, this is a server code:

for(i=0 ; i<Network.connections.length ; i++) 
{
    networkView.RPC("SetID", *specific client* , i );
}

client code:

[RPC]
SetID(int id)
{
    myID = id;
}
