/* A CGI script written in C to effect a simple XML-RPC server.
Example of use:
- Compile this as the executable 'xmlrpc_sample_add_server.cgi'
- Place the .cgi file in web server www.example.com's /cgi-bin
directory.
- Configure the web server to permit CGI scripts in /cgi-bin
(Apache ExecCgi directory option).
- Configure the web server to recognize this .cgi file as a CGI
script (Apache "AddHandler cgi-script ..." or ScriptAlias).
- $ xmlrpc http://www.example.com/cgi-bin/xmlrpc_sample_add_server.cgi \
sample.add i/5 i/7
