/* 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
|
|
