SunRPC is not then a suitable analogy. There is no socket interface that provides SunRPC as far as I know, so your example is invalid. Yes, SunRPC is built on top of something else, SOCK_DGRAM, SOCK_STREAM or whatever, but that's like saying TCP is a datagram service rather than a stream service because it's built on a datagram service (IP). What a protocol uses out the back is pretty much irrelevant - what is relevant is what the protocol in question actually appears to provide to anyone using it. > > I have made my client sockets use connect(), but that's just a > > convenience and I need to make it possible to avoid doing that to > > make it useful to the kernel.
