@values = $session->getfMultipleProperties( $object, 
       \@propNames,
       $freshness );

The getfMultipleProperties() function is like getMultipleProperties(), but refreshes values that are staler than $freshness seconds and need re-polling. The section “$freshness” on page 73 provides additional information.

The propNames argument must be a reference to an array of property names. For example,

 @props = qw(Vendor Model Type);
 ($v,$m,$t) =
  $session->getfMultipleProperties($obj, \@props, 30);
