/* A simple standalone RPC server based on an Xmlrpc-c packet socket.
|
|
|
|
This program expects the invoker to provide a socket in listen mode
|
|
as Standard Input.
|
|
|
|
This is not an XML-RPC server, because it uses a simple packet socket
|
|
instead of HTTP. See xmlrpc_sample_add_server.cpp for an example of
|
|
an XML-RPC server.
|
|
|
|
The advantage of this example over XML-RPC is that it has a connection
|
|
concept. The client can be connected indefinitely and the server gets
|
|
notified when the client terminates, even if it gets aborted by its OS.
|
|
|
|
Here's an example of running this:
|
|
|
|
$ socketexec -listen -local_port=8080 ./pstream_serial_server
|
|
