/* A simple standalone XML-RPC server program written in C as an example of
use of the Xmlrpc-c libraries.
This example expects an already bound socket on Standard Input, ready to
be listened on for client connections. Also see xmlrpc_sample_add_server,
which is the same thing, except you tell it a TCP port number and it
creates the socket itself. Also see xmlrpc_inetd_server.c, which is
the same thing except you give it a socket which is already connected
to a client.
Example:
$ socketexec -local_port=8080 ./xmlrpc_socket_server
