/* A simple standalone XML-RPC server program written in C. */
/* This server knows one RPC class (besides the system classes):
"sample.add".
The program takes one argument: the HTTP port number on which the server
is to accept connections, in decimal.
You can use the example program 'xmlrpc_sample_add_client' to send an RPC
to this server.
Example:
$ ./xmlrpc_sample_add_server 8080&
$ ./xmlrpc_sample_add_client
For more fun, run client and server in separate terminals and turn on
tracing for each:
$ export XMLRPC_TRACE_XML=1
