This is an example of how to implement an XML-RPC server by registering callbacks to specific methods and how to make xmlrpc calls using the builtin xmlrpc() factory provided by Drupal.

Code

function _xmlrpc_example_server_subtract($num1, $num2) {
  $diference = $num1 - $num2;

  // If result is not within maximum and minimum limits, return corresponding error
  if ($diference > variable_get('xmlrpc_example_server_max', 10)) {
    return xmlrpc_error(10001, t("Result is over the higher limit defined by the server."));
  }
  if ($diference < variable_get('xmlrpc_example_server_min', 0)) {
    return xmlrpc_error(10002, t("Result is under the lower limit defined by the server."));
  }

  // Otherwise return the result.
  return $diference;
}
